![]() True ligaments: Are condensations of pelvic fascia. Posterior surface: also called base of urinary bladder.ĭescribe in brief the supports of urinary bladder.įollowing are the Supports of urinary bladder :.Two inferolateral surfaces: Are related to pubic bone, retropubic fat and levator ani.Superior : Is triangular in shape and is related to coils of ileum and pelvic colon.It is pierced by internal urethral meatus.īorders: There are four borders – Anterior, Posterior, and two lateral. behind the lower part of pubic symphysis. In males it is related to prostate gland & in females to pelvic fascia. Neck: Is the lowest and most fixed part.In males it is related to ampulla of vas deferens and seminal vesicle. In females it is related to anterior vag vaginal wall. Base/Fundus/Posterior surface: Is triangular in shape.It is connected to the umbilicus by median umbilical ligament ( remnant of urachus). ![]() An apex: Lies at the level of upper border of pubic symphysis.Įmpty urinary bladder presents the following parts: Shape: It is tetrahedral in shape when empty and ovoid when distended. In infants: Urinary bladder is located in the abdominal cavity.In adults: Empty bladder lies in the pelvic cavity and the distended bladder rises above the pubic symphysis and reaches the hypogastric region of abdominal cavity.U rinary bladder is a hollow muscular viscus that acts as a reservoir of urine. 6 Describe briefly the nerve supply of urinary bladder.ĭescribe the location, shape and gross features of urinary bladder.5 Name the arteries supplying and the lymph nodes into which lymph drains from the urinary bladder.3 Describe briefly the trigone of bladder.2 Describe in brief the supports of urinary bladder.1 Describe the location, shape and gross features of urinary bladder.This area usually contains the fundus of the distended urinary bladder and can be clinically significant owing to the fact that the supravesical hernias can arise here.Īs previously mentioned, the main function of the median umbilical ligament in postnatal life is to provide support for the urinary bladder. ![]() The median and medial umbilical ligaments form a peritoneal depression on each side of the urinary bladder referred to as the supravesical fossae. median umbilical ligaments the medial umbilical ligaments are paired structures related to the umbilical arteries found either side of the median umbilical ligament. It is important to distinguish between the medial vs. The parietal peritoneum drapes over the median umbilical ligament, forming a peritoneal ridge known as the median umbilical fold. It is located roughly along the midline, between the two medial umbilical ligaments. The median umbilical ligament extends from the apex of the urinary bladder to the umbilicus. In some cases, due to incomplete closure, it may persist as different variants, some regarded as normal, others as pathologic. In the postnatal period, it usually completely involutes, becoming part of the median umbilical ligament. This duct becomes progressively obliterated during fetal life. ![]() It contains the urachus, which is an embryonic remnant resulting from involution of the allantoic duct that connects the fetal urinary bladder to the umbilicus. The median umbilical ligament is a fibrous band located in the anterior portion of the abdomen, anterior to the urinary bladder. ![]()
