Merocrine (eccrine) sweat glands
A
usually are associated with hair follicles
B
respond primarily to elevated body temperature
C
respond primarily to emotional stress
D
usually are associated with hair follicles
Explanation: 

Detailed explanation-1: -Temperature regulation: If the body temperature begins to rise for any reason, the merocrine sweat glands produce sweat to cool the surface of the skin in order to help cool the temperature of the body.

Detailed explanation-2: -Eccrine sweat glands help to maintain homoeostasis, primarily by stabilizing body temperature.

Detailed explanation-3: -The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Detailed explanation-4: -Eccrine sweat glands receive sympathetic innervation via cholinergic fibers that send impulses in response to changes in core body temperature.
