COMBINED
Portion of the skin that
contains:
- Hair follicles What is the adnexa? Where is it found?
- Sebaceous glands
- Apocrine glands
Adnexa is embedded in
the dermis.

Basement membrane
scaffold for migrating keratinocytes during wound
(BM)
healing?
What kind of healing occurs if the basement
Heals by scarring
membrane of the epidermis is damaged?
Stratum basale Which layer of the epidermis houses stem cells for
keratinocyte proliferation?
Terminal differentiation of What is cornification?
keratinocytes
Shedding of cornified What is desquamation?
keratinocytes
(corneocytes)
How long does migration of skin cells from the
stratum basale to stratum corneum take?
22 days
(Essentially, how long does it take for complete
skin turnover?
Which cells in the epidermis are antigen-
Langerhans cells presenting cells with immunesurveillance
functions?
Merkel cells Which cells in the epidermis serve as
mechanoreceptors?
Collagen What substance provides strength in the dermis?
