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.

Santa Larvae
Hurry down my cecum tonight!
A nematode larva (Contracaecum) in the digestive tract of a seal. The eggs of this parasitic nematode use fish as an intermediate host before infecting piscivorous mammals, including humans who may forget to clean their holiday salmon!

Happy holidays everyone!

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.
Histology is from the microscope of the ‘fiancee of ned4spd8834’

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,
Camille

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.
