block8_21.jpg - Fig.12 93W7125, Ureter (cs) , HE. The thick epitheliai liningis the transitional epithelium (Ep). The remainder of the wall ismade up of connective tissue (CT) and smooth muscle. Thetransitional epithelium and its supporting connective tissueconstitute the mucosa (Muc). A distinct submucosa is notpresent. The muscularis (Mus) is arranged as an innerlongitudinal layer (SM(l)), a middle circular layer (SM(c)), andan outer longitudinal layer (SM(l)). However, the outerlongitudinal layer is present only at the lower end of the ureter.By the way, there are blood vessels (BV) and lymphaticnodule (LN) in the serosa (Ser).
