block8_25.jpg - Fig.14 93W7130, Urinary bladder human (cs), HE. Thetransitional epithelium (Ep) lining the bladder is seen on theleft. Beneath the epithelium is a relatively thick layer ofconnective tissue (CT) containing blood vessels of varioussizes. The epithelium and connective tissue constitute themucosa (Muc) of the bladder. The transitional epithelium isoften characterized by the presence of surface cells thatexhibit a "dome" shape. In addition, many of these surfacecells are binucleate (arrows). The muscularis (Mus) consistsof smooth muscle arranged as an inner longitudinal layer, amiddle circular layer, and an outer longitudinal layer, but it isless regularly arranged than the description indicates.

The muscularis (Mus) consists of smooth muscle arranged as an inner longitudinal layer, a middle circular layer, and an outer longitudinal layer, but it is less regularly arranged than the description indicates.
