The hair follicle wall is part dermis, part epidermis

The root hair plexus allows the hair to assist in touch sensation

The arrector pili muscle is attached to the follicle

The hair root contains only 2 layers

Nails are scale-like modifications of the epidermis

Nails, like hair, can provide information on your health

Nails contribute to the skin's function of water regulation

eccrine & sebaceous

eccrine & apocrine

apocrine & sebaceous

apocrine & mammary

Eccrine glands are found in the armpits & pubic regions, secrete sticky, cloudy "sweat" that bacteria like to "eat" & are hormonally controlled

Eccrine glands secrete sebum into hair follicles or directly onto the skin in certain regions of the body, & provides lubrication to hair shafts

Eccrine glands are located all over the body, release sweat directly onto the skin surface & play a major role in thermoregulation

Eccrine glands produce a "modified" sweat product called cerumen (earwax) that prevents foreign particles from entering the ear

water

salts

metabolic waste

microbe-killing peptides

antibodies

Apocrine glands are found in the armpits & pubic regions, secrete sticky, cloudy "sweat" that bacteria like to "eat" & are hormonally controlled

Apocrine glands secrete sebum into hair follicles or directly onto the skin in certain regions of the body, & provides lubrication to hair shafts

Apocrine glands are located all over the body, release sweat directly onto the skin surface & play a major role in thermoregulation

All apocrine glands produce a "modified" sweat product called cerumen (earwax) that prevents foreign particles from entering the ear

Consists of sweat, proteins, & fatty substances

It's viscous; usually milky or yellowish

It's odorless - until bacteria interacts with it

These secretions are hypothesized to be a sexual scent

Sebaceous glands are found in the armpits & pubic regions, secrete sticky, cloudy "sweat" that bacteria like to "eat" & are hormonally controlled

Sebaceous glands secrete sebum into hair follicles or directly onto the skin in certain regions of the body, & provides lubrication to hair shafts

Sebaceous glands are located all over the body, release sweat directly onto the skin surface & play a major role in thermoregulation

Sebaceous glands produce a "modified" sweat product called cerumen (earwax) that prevents foreign particles from entering the ear
