This is due to the convoluted mucosa. The new cells migrate to the lumen. An inner epithelium lining of mucosa membrane or tunica mucosa.

This is a transverse section through the ureter. The basal cell layer renews the urothelium by cell division. Mudassar Ali Roomi MBBS MPhil Ureter The wall of ureter is composed of following three coats.

The nephron is a microscopic structure that is made of blood capillaries. The function of the ureter is to transport urine from the renal pelvis toward the bladder and to protect the renal parenchyma from distally generated backflow and back pressure. Notice the transitional epithelium of the mucosal lining the smooth muscle in the.

Middle smooth muscles layers two or three muscle layers or tunica muscularis. The ureter truly commands a rather unique position in anatomic studies owing chiefly to its ever-changing internal lining and its highly specialized muscular coatings 416.
