The sudoriferous glands and the sebaceous glands have different secretions, structures, and purposes. Which pairing is correct?
Explanation
Sudoriferous (sweat) glands are coiled tubular structures in the dermis that secrete a thin watery fluid of water, sodium chloride, and urea directly onto the skin surface through their own pores; their main job is thermoregulation, with apocrine variants in the axilla and groin contributing to body odor. Sebaceous (oil) glands are saclike, holocrine, attached to nearly every hair follicle except palms and soles; they secrete sebum (a lipid mixture from the breakdown of the gland's own cells) into the upper portion of the hair follicle, lubricating skin and hair. Neither secretes melanin. Cosmetologists rely on this anatomy under Bus. & Prof. Code §7320.
