Esoph-egg-us
✅Non-keratinized stratified squamous epithelium
✅Circumscribing muscularis mucosae
✅Submucosal glands
✅Dual layered muscularis externa
It’s just not Spring until you have painted your very own Esoph-egg-us
So get cracking and I don’t want to hear any eggscuses

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.
☘️Shamrock Gloms ☘️
For each petal on the shamrock,
This brings a wish your way.
Good health. Good luck. Happiness.
For today and every day.
Happy St. Patrick’s Day!
Three renal corpuscles (glomerulus + their surrounding Bowman’s capsules) floating in a sea of distal and proximal convoluted tubules within the cortex of the kidney.
These three small structures are knotted balls of capillaries (glomeruli) surrounded by a specialized epithelium (Bowman’s capsule) that is composed of cells called podocytes. These cells have tiny interlocking legs that form a small slit between them.
This structural organization is responsible for filtering your blood to produce a fluid that then travels within tubes continuous with the Bowman’s capsule called nephrons. In these nephrons the tubular fluid is modified by reabsorbing and secreting ions and conserving water to produce urine for excretion.

Dividing pyrotechnics!
Don’t forget to review the stages of mitosis while watching the fireworks this weekend!
It looks like this one is in metaphase!
Happy 4th of July!
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.
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.

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.

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