This image shows the
wall of the anal canal near the anal orifice. This portion of the anal canal
is covered by hairless skin, consisting of epidermis
(Ep) and its underlying dermis (De). The
epidermis is a typical keratinizing stratified squamous
epithelium (KSSE) with a prominent stratum corneum
(SC). The dermis is loose connective tissue in the papillary
layer (PL) closest to the epidermis, from which dermal
papillae (DP) arise. The deeper, reticular layer
(RL) , is dense irregular connective tissue.
