Document Summary
Urinary systems 2 ureter, urinary bladder & urethra. Objectives: describe the course of the ureter. Where are kidney stones most likely to lodge: describe the urinary bladder, with special reference to the trigone, describe the structures and neural mechanisms which regulate micturition. Compare the urethra of the male with that of the female. Expandable muscular tubes: begin at level l2. Convey urine from kidney to bladder: recall that kidneys are t12-l3. Enters pelvis at bifurcation of common iliac artery: ureteropelvic junction, pelvic brim/inlet as the ureters pass over the common iliac arteries, as ureters enters into the bladder wall. Stones can form in kidney and travel through ureter: may get lodged along the way. Bladder: urachus (in embryo) = median umbilical ligament (in adult, hooks up the apex of the bladder to the anterior abdominal wall (near belly button) Posterolateral angles (two) contain the insertion point for ureters: this side of the bladder is known as the base.
