BIOM20002 Lecture Notes - Lecture 62: Perineal Membrane, Pelvic Floor, Pelvic Brim
Document Summary
During development kidneys appear to move up because different growth rates makes it look like its moving. It develops in pelvis so it takes the accessory renal artery from pelvis. May directly enter hilum or may pierce surface of kidney to get in. Uretopelvic junction: just after renal pelvis becomes ureter. Traversing bladder wall (a functional sphincter preventing urine reflex) When bladder contracts, urine may go backwards however the functional sphincter prevents this. Small kidney stones can pass out of urine. But usually kidney stones situate at each constriction. The bladder is relatively free except for its neck. Bladder neck is the most inferior part and held firmly by ligaments which surround the bladder inferiorly. Limits ascent of bladder as it gets full. Full bladder goes up into abdomen, can push abdominal contents up to diaphragm. 2 top openings (ureteric orifices) are for ureters to come in.
