Block8/Fig.11 93W7125, Ureter (cs) , HE.

block8_19.jpg - Fig.11 93W7125, Ureter (cs) , HE. As shown in this low-power orientation micrograph, the wall of the ureter consistsof a mucosa (Muc), a muscularis (Mus), and an adventitia(Adv). Note that the ureters are located behind theperitoneum of the abdominal cavity in their course to thebladder. Thus, a serosa (Ser) may be found covering aportion of the circumference of the tube. Also, because ofcontraction of the smooth muscle of the muscularis, theluminal surface is characteristically folded, thus creating astar-shaped lumen.
