SKIN DIAGRAM Let’s Label it Up!

SKIN Diagram - LEFT Epidermis Dermis Hypodermis (subcutaneous)

SKIN Diagram - RIGHT Hair shaft

SKIN Diagram - RIGHT Stratum corneum S. lucidum S. granulosum Stratum spinosum Stratum basale

SKIN Diagram - RIGHT Sebaceous (oil) gland

SKIN Diagram - RIGHT Arrector pili muscle Nerves

SKIN Diagram - RIGHT Hair follicle Papilla of hair bulb Adipose

SKIN Diagram - RIGHT Sudoriferous (sweat) glands

Why is this a “mutant” section of skin? Stratum lucidum is only present in hairless areas of skin

How does the skin do it? In lower layers of the epidermis cells are dividing because they are close to the blood supply of the dermis. As cells are pushed up to surface they die off and gain more keratin.

NAIL DIAGRAMS Let’s Label it Up!

TOP Nail Diagram – on LEFT Lunula Cuticle

TOP Nail Diagram – on RIGHT nail body/plate lateral nail fold

Sagittal View Nail Diagram – on LEFT Nail root Nail matrix

Sagittal View Nail Diagram – on RIGHT cuticle nail body/plate free edge bone/osseous tissue stratum basale

Why do nails look pink? Nails look pink due to the blood supply of the dermis

What area of the nail is responsible for nail growth? The nail matrix is responsible for nail growth. -> The lunula appears white due to the thickened stratum basale underneath
