ANSWERS-melanocytes
active

The ________ plays a viral role in maintaining the body's temperature and homeostasis. -
ANSWERS-skin
_________________ are dendritic cells in the epidermis that have an immunologic function -
ANSWERS-Langerhans cells
Langerhan cells are identical to ________ ________________ and present antigens to
lymphocytes with which they interact via specific surface receptors. - ANSWERS-tissue
macrophages
The interface between the epidermis and dermis is called - ANSWERS-Basement membrane
zone (BMZ)
Electron microscopic examination reveals 3 layers: - ANSWERS-1. lamina lucida
2. basal lamina
3. anchoring fibrils
Lamina lucida - ANSWERS-relatively lucid zone transversed by delicate anchoring filaments that
connect the cell membrane of the basal cell with the basal lamina
Basal lamina - ANSWERS-the basal lamina an electron- dense zone composed primarily of type
IV collagen derived from epidermal cells and anchoring fibrils
Anchoring fibrils - ANSWERS-which are thick fibrous strands, composed primarily of type VII
collagen, that complete the connection with the dermis
, The BMZ - ANSWERS-serves as the "glue" between the epidermis and dermis and is the site of
blister formation in a number of diseases.

The matrix and papilla house the - ANSWERS-bulge and the bulb

In the scalp, androgens cause hair to change from _______ to _____________. - ANSWERS-
vellus to terminal
Once _________ hair has been transformed into terminal hair, it cannot change back even if
