What are the functions of the holocrine gland?
Holocrine is a term used to classify the mode of secretion in exocrine glands in the study of histology. Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.
What is true regarding apocrine sweat glands?
apocrine sweat gland. n.

What do eccrine sweat glands respond to?
Whereas all eccrine sweat glands respond to cognitive activity, emotion, and temperature, palmar and plantar sweat glands appear more responsive to emotional stimuli because of their higher density (about 1,000 glands per cm2, compared with 100–200 per cm2 on the trunk and limbs).
