Apocrine sweat gland. An apocrine sweat gland (/ËÃ¦pÉkrÉn/, /ËÃ¦pÉËkraÉªn/, or /ËÃ¦pÉËkrin/, from Greek apoâ away and krinein to separate) is composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle.
Sweat comes from exocrine glands. The pituitary gland is an endocrine gland that produces hormones. The endocrine system regulates the body's organ function using hormone-based signals. The pineal gland secretes melatonin, which promotes sleep.ndocrine glands secrete substances directly into the bloodstream. Exocrine glands tend to be relatively simple and have local effects, while endocrine ones release hormones that travel throughout the body. Most glands form in the embryo from epithelial tissue.
