Uberon Structure note : Ceruminous glands are simple, coiled, tubular glands made up of an inner secretory
layer of cells and an outer myoepithelial layer of cells. The glands drain into larger
ducts, which then drain into the guard hairs that reside in the external auditory
canal. Here they produce cerumen, or earwax, by mixing their secretion with sebum
and dead epidermal cells;
