This diagram shows a cross-section of human skin with its various layers and structures. Here are the labels corresponding to the letters in the image, moving generally from top to bottom and left to right:
Top Layer (Epidermis & Surface):
*
A: Epidermis (the outermost layer of skin)
*
B: Hair shaft (the part of the hair visible above the skin)
*
C: Pore (opening of the sweat gland duct)
Middle Layer (Dermis):
*
D: Arrector pili muscle (tiny muscle that makes hair stand up)
*
E: Dermis (the thick middle layer containing blood vessels and nerves)
*
F: Nerve endings (sensory receptors)
*
G: Hair follicle (the structure surrounding the hair root)
*
H: Sebaceous gland (oil gland attached to the hair follicle)
*
I: Sweat gland duct (tube carrying sweat to the surface)
*
J: Sweat gland (coiled structure that produces sweat)
*
K: Vein (blood vessel carrying blood back to the heart)
*
L: Artery (blood vessel carrying blood to the skin)
*
M: Pacinian corpuscle (pressure sensor deep in the skin)
Bottom Layer (Hypodermis/Subcutaneous):
*
N: Hypodermis or Subcutaneous tissue (fatty layer under the dermis)
*
O: Adipose tissue (fat cells)
Hair Structure Details:
*
P: Root sheath (inner lining of the hair follicle)
*
Q: Hair root (part of the hair below the surface)
*
R: Dermal papilla (base of the follicle supplying nutrients)
*
S: Blood capillaries (tiny blood vessels)
*
T: Stratum basale (deepest layer of the epidermis where new cells form)

M: Pacinian Corpuscle
N: Hypodermis (Subcutaneous Layer)
O: Adipose (Fat) Tissue
P: Root Sheath
Q: Hair Root
R: Dermal Papilla
S: Capillaries
T: Stratum Basale
