This is the 97th post. 97 posts on a blog, none of which holding true value. Then again, this is a blog. Blogs don't typically hold value.
So, to make this post mean something, I'm going to teach you all some shit I've learned in anatomy!
(insert feeble "yay")
The Five Layers of the Epidermis:
Stratum Corneum - 20-30 cell layers thick, provides protection from external environment, dead cells. Thicker in thick skin.
Stratum Lucidum (only found in thick skin) - Clear layer.
Stratum Granulosum - 2-5 cell layers thick, contains keratohyaline, granules and lamellated bodies.
Stratum Spinosum - Several layers thick, lots of desmosomes (gives spiky appearance).
Stratum Basale - Deepest layer, one layer thick, mitosis occurs here.
Dermis: Below the epidermis. Connective tissue layer of skin. Richly supplied with nerves, blood vessels, lymphatics, oil & sweat glands.
Divided into two regions: Papillary layer, reticular layer.
Papillary layer: Superficial layer of the dermis, composed of connected issue, has projections called dermal papillae which indent the epidermis.
Reticular layer: Under papillary layer, composed of connective tissue. Separation of Papillary layer and epidermis results in blister.
Hypodermis: attaches skin to organs and tissues. Not part of skin. Connective tissue and adipose tissue for “insulation”. Infants and elderly have less, are more sensitive to cold.
That's all I'll provide today.
Congratulations, you might have learned something new today!
