Vesical Veins
The vesical veins are veins in the pelvis that drain blood from the urinary bladder. The vesical veins receive blood from the vesical venous plexus and are tributaries of the internal iliac vein The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to for ...s.

Pelvis
The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and ...

Urinary Bladder
The bladder () is a hollow organ in humans and other vertebrates that stores urine from the Kidney (vertebrates), kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. In humans, the bladder is a distensible organ that sits on the pelvic floor. The typical adult human bladder will hold between 300 and (10 and ) before the urge to empty occurs, but can hold considerably more. The Latin phrase for "urinary bladder" is ''vesica urinaria'', and the term ''vesical'' or prefix ''vesico-'' appear in connection with associated structures such as vesical veins. The modern Latin word for "bladder" – ''cystis'' – appears in associated terms such as cystitis (inflammation of the bladder). Structure In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad (base), a body, an apex, and a neck. The apex (also called the vertex) is directed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesical Venous Plexus
The vesical venous plexus is a venous plexus situated at the fundus of the urinary bladder. It collects venous blood from the urinary bladder in both sexes, from the accessory sex glands in males, and from the corpora cavernosa of clitoris in females (via the v. dorsalis profunda clitoridis). It drains into the internal iliac veins via several vesical veins. Structure The vesical venous plexus envelops the inferior part of the bladder and the base of the prostate The prostate is an male accessory gland, accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male mammals. It differs between species anatomically, chemica .... Anastomoses It communicates with the pudendal and prostatic plexuses.

Internal Iliac Vein
The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein. Structure Several veins unite above the greater sciatic foramen to form the internal iliac vein. It does not have the predictable branches of the internal iliac artery but its tributaries drain the same regions. The internal iliac vein emerges from above the level of the greater sciatic notch It runs backwards, upwards and towards the midline to join the external iliac vein in forming the common iliac vein in front of the sacroiliac joint. It usually lies lateral to the internal iliac artery. It is wide and 3 cm long. Tributaries Originating outside the pelvis, its tributaries are the gluteal, internal pudendal and obturator veins. Running from the anterior surface of the sacrum are the lateral sacral veins. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superior Vesical Artery
The superior vesical artery supplies numerous branches to the upper part of the bladder. This artery often also gives branches to the vas deferens and can provide minor collateral circulation for the testicles. Structure The superior vesical artery, a vital component of the pelvic vascular system, stems from the umbilical artery, which serves as a conduit for oxygenated blood during fetal development. Emerging typically as a single vessel, the superior vesical artery exhibits consistent anatomical features across individuals. Its trajectory leads it towards the superior aspect of the bladder, where it branches intricately to supply blood to this organ and surrounding structures. In males, a noteworthy branch arising from the superior vesical artery is the vesiculo-prostatic artery. This branch extends its reach to the prostate gland, contributing to its vascularization. The consistent presence of this arterial branch underscores its significance in male pelvic anatomy and physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Vesical Artery
The inferior vesical artery (or inferior vesical artery) is an artery of the pelvis which arises from the internal iliac artery and supplies parts of the urinary bladder as well as other structures of the urinary system and structures of the male reproductive system. Some sources consider this vessel to be present only in males, and cite the vaginal artery as the homologous structure in females; others consider it to be present in both sexes, with the vessel taking the form of a small branch of a vaginal artery in females. Structure Origin The inferior vesical artery is a branch of the anterior division of the internal iliac artery. It frequently has a common origin with the middle rectal artery. Course The inferior vesical artery passes medially across the pelvic floor. Distribution The inferior vesical artery is distributed to the trigone and inferior portion of the urinary bladder, the ureter, prostate, vas deferens, and seminal vesicles.vas deferens The vas ...
