The Mayans developed great dental skills most likely for ritual, or religious purposes. It is believed that dental modifications were used to identify with a polity, ruler, region, or lineage. The Mayans placed carved stone inlays into prepared cavities on the front teeth. Minerals like jadeite, sepentine, pyrite, cinnabar, turquoise, hematite, and iron pyrites imbedded in these cavities can be observed in person at the Mexico City museum. To make the cavity on the enamel, the Mayans used a copper tube. The tube was spun between the hands, and powered quartz in water was incorporated as a means of making it abrasive. This action leads to the creation of a round hole on the tooth enamel. The stone inlays were grounded to fit exactly into the cavity. Younger children teeth have not been found with these modifications.

Star Wars histology from top left, clockwise:
1. The Graafian follicle Death Star
In a galaxy far, far away an intergalactic superweapon is halted in metaphase II of meiosis amid a surge in Luteinizing Hormone.
2. Jabba the Corpus Albicans
“makingsa lee ka bok pateesa… beeska chata wnow kong bantha poodoo”
(translation) “you may have been a good friend..but now you are bantha fodder”
The corpus albicans is a structure in the ovary that is formed when the corpus luteum regresses.
3. Tusken Raider in the Liver
Despite what you see here, Tusken Raiders are not native to the human liver. If you think that, then you are making a wookie mistake.
The image is actually a portal triad and demonstrates the major structures that enter and leave the liver: hepatic artery, hepatic portal vein and bile duct.
4. The Empire Strikes Back (at the Liver)
Liver histology is definitely where it’s At-At!
A region of connective tissue among the hepatocytes in the liver.

Grumpy Cord
A transverse slice through a spinal cord that looks like Grumpy Cat.
Being the center of the nervous system, transmitting neural signals between the brain and the entire body and controlling independent neural reflexes…is just so awful .
The pale central face is the ‘grey matter’ and is home to the many neuron cell bodies that run through the spinal cord. The surrounding darker region is composed of the axons of these neurons as the exit, enter, ascend and descend through the spinal cord on their way to innervate muscles, or returning information about pain back from the skin, or relaying information about body position back to the brain.

Jurassic Pork
The pork tapeworm Taenia solium or a brachiosaurus?
i♡histo
This image shows the tapeworm T. solium, a parasite found in the bowels of humans who eat under-cooked pork.
You can see the proglottid segments of the worm’s neck/body and its terrifying scolex (head) complete with a hooked rostellum which it uses to attach itself onto your intestinal wall so that you don’t poop it out easily.
Fully grown worms can expand to around 2-3 meters in length and are composed of numerous segments each of which form their own reproductive unit.
The life cycle of the parasite begins when pigs ingest the T. solium eggs (from fecal contamination). The eggs develop into larvae inside the pig & then migrate through the intestinal wall to form cysts in their muscles & tissues.
Once slaughtered for meat, the larvae can be ingested by humans if the pork is eaten raw or under-cooked. Once in the human small intestine the larvae grow into large adult worms where they persist often unnoticed due to the lack of symptoms associated with their existence. The worms lay eggs into the intestines which are released during defecation thus continuing the life cycle.
“Life finds a way” - Dr. Ian Malcolm, Jurassic Park
A major complication of infection with T. solium is Cysticercosis. This is a parasitic tissue infection caused by the larval cysts of the tapeworm. These larval cysts infect brain, muscle, or other tissue, and are a cause of adult onset seizures. A person only gets cysticercosis by swallowing the eggs found in the feces of a person who has an intestinal tapeworm NOT from contracting a tapeworm by eating under-cooked pork itself. So people living in the same household with someone who has a tapeworm have a much higher risk of getting cysticercosis than people who don’t because they can be exposed to the eggs released in the stool.

SpongyBone SquarePants
Who lives in a bony medullary cavity?
Cancellous and yellow and porous is he.
Spongy bone!
Spongy bone is so named because its morphology (interconnected bony trabeculae/rods surrounding marrow spaces) resembles that of a sponge!
You can find spongy bone within flat bones (it forms the diplöe) and in long bones where it is located in the epiphyses (the ends of the bone) and diaphysis (the shaft of the bone).
Don’t be deceived by its name though. Spongy bone is not soft and spongy - it is still very strong, mature bone. It’s meshwork of trabeculae gives the inside of your bones strength and structure but at the same time, the space makes them more lightweight.
Spongy bone is always surrounded by a layer of compact bone (aka cortical bone).
Compact/cortical bone is different from spongy bone. It is named after the fact that it is more dense (i.e it isn’t made of rods and doesn’t have large spaces in it) and forms the outer aspect of a bone. If your bones were made entirely of compact bone than they would be much heavier and there would be no room for your bone marrow which is essential for making red and white blood cells.
Other names for spongy bone include ‘cancellous’ or 'trabecular’ bone.
A Pacinian Fingerprint at the Scene of the Crime
With all of this criminal activity it’s not surprising the body is full of cells!
A Pacinian or lamellar corpuscle is a mechanoreceptor that is most frequently found at the junction of the dermis/hypodermis in the skin. They are particularly prominent in the skin of the fingers and palms. In addition to the skin they are also found in other organs (e.g. mesentery, pancreas).
These very unique fingerprint-like structures have characteristic whorls formed from concentric lamella. Each lamella is separated from the next by a fluid filled space. And each lamella is lined on its inner and outer surface by connective tissue synthesized by the fibroblasts also in this region (you can see the nuclei of the fibroblasts in these lamellae in this image).
A nerve runs from the inner core of the corpuscle and is responsible for the transduction of mechanical forces applied to the skin into electrical signals that are conveyed to the central nervous system via the dorsal root ganglion.
This organization of fluid filled lamella and a central nerve are highly sensitive to pressure, particularly vibrational forces generated during tasks that involve a manipulative or tactile nature, like sensing the texture of a surface that is touched.
In fact, the screen of the phone/tablet you are using right now has been designed with the specific intention of stimulating the Pacinian corpuscles in your finger as you scroll.
So why not test out the Pacinians of your index finger for a moment by liking this post and following!! :-)

Easter Bunny Blood Cell
This monocyte is declaring a warren germs!
And doesn’t carrot all about what he phagocytoses.
He’ll just hop right to it.
Original source of histology is unknown
Which came first?
A seasonal conundrum in some keratin debris within a benign lymphoepithelial cyst.
Happy Spring & Happy Easter everyone!
The image shows a swirl of keratin debris (the chicken) in a small epithelial cell nest (the egg). The salivary gland is packed full of lymphocytes (the many, many purple nuclei surrounding the epithelial nest) which are a type of white blood cell.
Salivary gland lymphoepithelial cyst like this are rare and benign. Once the cyst is removed surgically from the gland it rarely recurs.
The Ro-lung Stones
The Stones’ ‘Hot Lips’ logo formed from a blood vessel filled with erythrocytes within a congested zone around a focal pneumonia of the lung.
During the first stages of focal/lobar pneumonia macrophages (the larger cells that are visible in the white alveolar space) respond to phagocytose (eat) any pathogens in the lung.
Additionally, the small blood vessels within the lung tissue begin to engorge (you can see all the erythrocytes in the dilated vessels not only in the large 'hot lips’ vessel but the smaller vessels in the interalveolar septa between adjacent alveoli). This is the congestion phase.
With this dilation of vessels come more white blood cells, you can see numerous neutrophils (they are the small cells that look like they have multiple lobes to their purple nuclei) have migrated out of the vessels (a process called extravasation) into the surround tissue and alveolar spaces. These cells are signs of an additional immune response and they help the macrophages destroy pathogens in the airway.

Blobfish-face
A coronal section through a developing jaw (when flipped upside down) looks like poor old blobfish!
The blobfish eyes are formed from Meckel’s cartilage. A component of the first pharyngeal arch that runs the length of the developing mandible. It degenerates as the fetus develops leaving only two small components on each side of the head. These ossify (become bone) to form the incus & malleus (ear ossicles) of the middle ear.
The blobfish nose is the developing tongue. It is composed of developing skeletal muscle fibers. Skeletal muscle forms from myoblasts that line up & fuse to form long myotubes. These will then synthesize actin/myosin which will allow them to contract & form the intrinsic skeletal muscle of the tongue.
The blobfish chin is formed by the developing maxilla. Two regions of tissue (the palatine shelves) grow together & fuse in the midline to form the posterior hard palate. You can see the midline suture forming & feel it in your own mouth by running your tongue along the roof of your mouth. Failure of these to fuse results in a variety of cleft lip and palate combinations.
The blobfish head is formed from a developing mandible. You can see small islands of bone forming within the mesenchymal tissue of the head. This type of bone development is called intramembranous ossification.
The blobfish is native to coastal waters off mainland Australia and Tasmania where it lives way deep down in the darkest depths of the ocean. Its gelatinous body is ideal for withstanding the pressure down there but when brought to the surface it looks like a sad melted pink crayon.

The Creepiest Fibroblast You Will Ever See
With a nucleus straight from the fiery depths of hell*
*Note: Fibroblasts do not come from hell. They are actually derived from embryonic mesoderm and the creepiest thing they do is secrete the collagen and ground substance of connective tissue. Not very creepy at all really when you think about it.

This image showing dental work on a mummy from ancient Egypt is evidence of ancient dentistry. Archaeologists believe this mummy was from around 200 BCE.

The earliest evidence of ancient dentistry we have is an amazingly detailed dental work on a mummy from ancient Egypt that archaeologists have dated to 2000 BCE. The work shows intricate gold work around the teeth. This mummy was found with two donor teeth that had holes drilled into them. Wires were strung through the holes and then around the neighboring teeth.

Hello Tumblr! Update: I started my summer classes two weeks ago at a new uni. As some of you may know, I left my old school and chose to study at a bigger university. After all inquiries and deliberations, I got accepted at Centro Escolar University-Makati School of Dentistry! Quite a leap for me but I’m trying not to get too anxious

This semester started as a blur. We had four months of summer vacation since the school year adjusted from June-November to August-December (First semester). That was a long period to enjoy all that summer has to offer but believe me, it was a rush and it came by like the wind. I spent my days slouching around, watching Korean dramas, movies, American TV series and made a little bit of art.
August came. We’re all super excited for the subjects ahead because finally, we can be able to buy cool stuff like typodonts, new handpieces, burs, and micromotor. We’ve been peeking around our seniors doing their works at the simulator. Dental materials, instruments, and supplies are too expensive. By the first and second week, we already had the list of things that we need to buy. I think we spent around 20,000 to 30,000 pesos on one trip to Quiapo Manila alone. Take note, as the months progressed we need to buy more.
Aside from major dental subjects like Restorative Dentistry I, Prosthodontics I, Oral Radiology and Oral Physiology and Occlusion, we’re left with medical subjects like Pharmacology and General Pathology. Those two subjects took most of my studying time for the reason that our professors in those subjects are medical doctors, so what can you expect? We were taught like MDs and that was very grueling for us.
My class schedules were 7 am to 7 pm on Mondays to Fridays. I arrived home at around 8 pm. My one hour journey home was stressful because of the traffic and heat in the Philippines, luckily, I easily fell asleep on my commute. Yehey for power naps! When I got home, I slept first for 2 hours or so and then studied the whole night/morning. I slept again at around 4:30 am and woke up at 5:30 am and repeated the whole cycle again and again for 5 months.
Prelim came. Midterm came. Finals came. I passed all my subjects! I can’t wait to share some more of my school stories, works, notes, and planner spread in this blog.
To dentistry & everything in between,

Hello guys! Help me decide. To which dental school should I transfer? Enlighten me. Thank you! (Btw, I’m from the Philippines, Cavite specifically)

Sorry for not posting for a while, I’ve been dealing with an art/blog/instagram crisis lately. Posting some content had been terrifying and stressful, I don’t know why. I hope I’ll get better with everything because I can’t wait to write about my last semester, organizing, journaling, my subjects and all.
Since I’m transferring schools, I have plenty of leisure time to do so. Most days, I just sit around and browse the web. But lately, I’ve been reading novels. The last one I read was Aristotle and Dante discover the secrets of the universe by Benjamin Alire Saenz, my TBR this month are We are okay by Nina LaCour, Looking for Alaska by John Green (reread), Perks of being a wallflower by Stephen Chbosky (reread), Harry Potter and the sorcerer’s stone (sorry for reading it just now, I just got stuck) Got all my books from Fullybooked. I’m so thrilled to do all my plans! Wish me luck.

Made the boldest decision in my life so far. I’ve decided to transfer to another school for my 2nd year dental proper. It’ll take another year for me to graduate but I know this will work for the better.
For now, I’m having 4-5 months of vacation. Yey for me.
