Ceruminous glands are simple, coiled, tubular glands made up of an inner secretory layer of cells and an outer myoepithelial layer of cells. [1] They are classed as apocrine glands. The glands drain into larger ducts, which then drain into the guard hairs that reside in the external auditory canal. [2]
It is a mixture of secretions from sebaceous glands and less-viscous ones from modified apocrine sweat glands. [4] The primary components of both wet and dry earwax are shed layers of skin, with, on average, 60% of the earwax consisting of keratin, 12–20% saturated and unsaturated long-chain fatty acids, alcohols, squalene and 6–9% ...

sweat gland. Skin secretions are those substances and materials that are secreted by the skin and the external mucous membranes. Some skin secretions are associated with body hair. Skin secretions originate from glands that in dermal layer of the epidermis. Sweat, a physiological aid to body temperature regulation, is secreted by eccrine glands.
The ear canal ends at the external surface of the eardrum, while the surrounding skin contains ceruminous and sebaceous glands that produce protective earwax. [3] Earwax naturally migrates outward through ear canal, constituting a self-cleaning system.

Eccrine glands on their foot pads, like those on palms and soles of humans, did not evolve to cool either but rather increase friction and enhance grip. Dogs and cats have apocrine glands that are specialized in both structure and function located at the eyelids (Moll's glands), ears (ceruminous glands), anal sac, clitoral hood, and circumanal ...
