Eccrine sweat glands: distributed all over the body and are utilized primarily for cooling via sweating
Secretion from eccrine sweat glands is triggered by muscarinic receptor stimulation.
Apocrine sweat glands: limited to the armpits and perianal areas in humans.
Secretion from apocrine sweat glands is triggered by alpha-1 receptor stimulation.
Both eccrine and apocrine sweat glands are innervated by postganglionic sympathetic fibers. Eccrine sweat glands are responsible for the majority of sweat gland secretion and use ACh as the neurotransmitter (acts on muscarinic receptors).
a) Apocrine sweat glands secrete primarily for cooling
b) Eccrine sweat glands are found only in specific areas of the body
c) Eccrine sweat glands use alpha-1 receptor stimulation
d) Eccrine sweat glands are primarily responsible for sweat secretion
