Question

question 2
the nerve fibers in the dermis stimulate:
a blood vessels in the epidermis
b muscles and glands in the dermis
c fat cells in the subcutaneous layer
d melanocytes in the epidermis

Explanation:

The dermis contains nerve fibers that are associated with muscles (like arrector pili muscles) and glands (such as sweat glands and sebaceous glands). The epidermis has no blood vessels (so A is wrong). Fat cells in the subcutaneous layer (hypodermis) are not directly stimulated by dermis nerve fibers in the way the question implies (C is wrong). Melanocytes in the epidermis are mainly involved in pigment production and not directly stimulated by dermis nerve fibers for their main function (D is wrong).

Answer:

B. muscles and glands in the dermis
