Explanation:
Detailed explanation-1: -The ceruminous glands in the skin of the human external auditory canal are modified apocrine glands, which, together with sebaceous glands, produce the cerumen, the ear wax.
Detailed explanation-2: -Apocrine sweat glands, which are usually associated with hair follicles, continuously secrete a fatty sweat into the gland tubule. Emotional stress causes the tubule wall to contract, expelling the fatty secretion to the skin, where local bacteria break it down into odorous fatty acids.
Detailed explanation-3: -Modified apocrine sweat glands include the wax-producing ceruminous glands of the external auditory meatus, the Moll glands found at the free margins of the eyelids, and the mammary glands of the breast.
