Deep, coarse, bulbous terminal hair (as on chins) - correct answer-5 to 6 weeks
Average time of hair, reappearance after tweezing or waxing:
Medium depth, terminal hair (as on side of face and body) - correct answer-6 to 7 weeks
Average time of hair, reappearance after tweezing or waxing:
Medium depth intermediate or accelerated vellus hair - correct answer-7 to 9 weeks
Average time of hair, reappearance after tweezing or waxing:
Shallow vellus hair (downy, general face) - correct answer-8 to 10 weeks*
Ultraviolet rays from sunlight react with the amino acid ____________ found in the
melanocytes and produce melanin - correct answer-tyrosine
Generally, people of different races have approximately the same number of
______________.
People with dark skin have melanocytes that are more _________ and produce more
melanin. - correct answer-melanocytes
active
The follicle _________ to about a third of its anagen size. - correct answer-shrinks
The ________ plays a viral role in maintaining the body's temperature and homeostasis. -
correct answer-skin
_________________ are dendritic cells in the epidermis that have an immunologic function -
correct answer-Langerhans cells
Langerhan cells are identical to ________ ________________ and present antigens to
lymphocytes with which they interact via specific surface receptors. - correct answer-tissue
macrophages
The interface between the epidermis and dermis is called - correct answer-Basement
membrane zone (BMZ)
Electron microscopic examination reveals 3 layers: - correct answer-1. lamina lucida
2. basal lamina
3. anchoring fibrils
, Lamina lucida - correct answer-relatively lucid zone transversed by delicate anchoring
filaments that connect the cell membrane of the basal cell with the basal lamina
Basal lamina - correct answer-the basal lamina an electron- dense zone composed primarily
of type IV collagen derived from epidermal cells and anchoring fibrils
Anchoring fibrils - correct answer-which are thick fibrous strands, composed primarily of type
VII collagen, that complete the connection with the dermis
The BMZ - correct answer-serves as the "glue" between the epidermis and dermis and is the
site of blister formation in a number of diseases.
It appears that there are two areas of target: - correct answer-the bulge and the bulb
The matrix and papilla house the - correct answer-bulge and the bulb
The total number of follicles is approximately _________ in men and women, and appears to
be the same in all races. - correct answer-equal
It is the activity of the ____ _______, rather than their number which determines the amount
of growing hair. - correct answer-hair follicles
The most important hormone controlling growth are "____________" commonly known as
"male" hormones - correct answer-androgens
The most important hormone is - correct answer-testosterone
In the scalp, androgens cause hair to change from _______ to _____________. - correct
answer-vellus to terminal
Once _________ hair has been transformed into terminal hair, it cannot change back even if
androgen disappear.
Therefore, ____________ must be treated promptly to minimize the number of terminal hairs
induced by the excess androgens. - correct answer-vellus
hirsutism
Electrolysis should not be performed until hormonal therapy has been used fir at least.
Otherwise, it will result in an endless "chasing" of new coarse hairs throughout the body -
correct answer-6 months.
Sexual hair i.e,, facial, ear, chest, abdominal, pubic and axillary, is ______________
dependent and this hormone is primarily ______________, which is converted to
dihydrotestosterone before it becomes effective. - correct answer-hormone dependent
testosterone
