True

False


Question 3 2 pts

Stratum corneum

Stratum granulosum

Stratum spinosum

Stratum basale


Question 4 2 pts

A. True

B. False

Answer 1

1.A piece of hair is forcibly removed from the scalp. If any connective tissue remained attached to the follicle cells, what type of connective tissue would you find?

Mostly dense irregular

(Hair follicles are located in the reticular layer of dermis which is mostly composed of dense irregular connective tissue)

2.Eccrine glands (not including the duct) are typically found in the stratum granulosum layer.

False

(Eccrine glands or sweat glands are mostly located deep in the dermis)

3.One cause of human albinism is a defect in the tyrosinase protein, an enzyme that helps to control melanin production. In what epidermal layer is tyrosinase functioning?

Stratum basale

(Tyrosinase is an enzyme which produces melanin of melanocytes found between cells of stratum basale.)

4.The papillary layer of the dermis is most closely associated with which layer of the epidermis?

Stratum basale

(The papillary dermis is the uppermost layer of the dermis while stratum basale

 Is the lowest layer of epidermis)

 

5.The stratum lucidum is present in both thick and thin skin.

False

(The stratum lucidum is found only in thick skin of palms of the hands and the soles of the feet.)
