Study Notes
- The dermal-epidermal junction supports the epidermis and acts as a barrier.
- Basal keratinocytes are important components of the junction.
- Skin adnexa are ectodermally derived appendages.
- Eccrine sweat glands regulate heat and are most abundant on the soles of the feet.
- Apocrine sweat glands are involved in scent release and are found in the axillae and perineum.
- Apoeccrine sweat glands develop during puberty and open directly unto the skin.
- All adnexal structures are capable of re-epithelialization after injury.
- The secretory coil of the eccrine unit is composed of glycogen-rich clear secretory cells, dark mucoidal cells, and myoepithelial cells.
- The proteinaceous, viscous secretion of apocrine glands has a distinct odor and can function as a territorial marker, warning signal, and sexual attractant.
- AEG is found in the adult axillae and its relative frequency varies from person to person.
