Dorsal Artery Of Clitoris
The internal pudendal artery is one of the three pudendal arteries. It branches off the internal iliac artery, and provides blood to the external genitalia. Structure The internal pudendal artery is the terminal branch of the anterior trunk of the internal iliac artery. It is smaller in the female than in the male. Path It arises from the anterior division of internal iliac artery. It runs on the lateral pelvic wall. It exits the pelvic cavity through the greater sciatic foramen, inferior to the piriformis muscle, to enter the gluteal region. It then curves around the sacrospinous ligament to enter the perineum through the lesser sciatic foramen. It travels through the pudendal canal with the internal pudendal veins and the pudendal nerve. Branches The internal pudendal artery gives off the following branches: The deep artery of clitoris is a branch of the internal pudendal artery and supplies the clitoral crura. Another branch of the internal pudendal artery is the dor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Internal Iliac Artery
The internal iliac artery (formerly known as the hypogastric artery) is the main artery of the pelvis. Structure The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. The vesicular branches of the internal iliac arteries supply the bladder. It is a short, thick vessel, smaller than the external iliac artery, and about 3 to 4 cm in length. Course The internal iliac artery arises at the bifurcation of the common iliac artery, opposite the lumbosacral articulation, and, passing downward to the upper margin of the greater sciatic foramen, divides into two large trunks, an anterior and a posterior. It is posterior to the ureter, anterior to the internal iliac vein, anterior to the lumbosacral trunk, and anterior to the piriformis muscle. Near its origin, it is medial to the external iliac vein, which lies between it and the psoas major muscle. It is above the obturator ...

Pudendal Canal
The pudendal canal (also called Alcock's canal) is an anatomical structure formed by the obturator fascia (fascia of the obturator internus muscle) lining the lateral wall of the ischioanal fossa. The internal pudendal artery and veins, and pudendal nerve pass through the pudendal canal, and the perineal nerve arises within it. Clinical significance Pudendal nerve entrapment can occur when the pudendal nerve is compressed while it passes through the pudendal canal. History The pudendal canal is also known as Alcock's canal, named after Benjamin Alcock. Additional images Image:Gray542.png , The superficial branches of the internal pudendal artery.

Dorsal Artery Of The Penis
The dorsal artery of the penis is a bilaterally paired terminal branch of the internal pudendal artery which passes upon the dorsum of the penis to the base of the glans penis, where it unites with its contralateral partner and supply the glans and foreskin. The dorsal artery of the penis provides blood supply to the skin and fascia of the penis (including the foreskin), and the erective tissues of the penis (especially the glans penis). The dorsal artery of the penis may be damaged in traumatic amputation of the penis and repairing the dorsal artery surgically prevents skin loss, but it is not essential for sexual and urinary function. Its hemodynamics and blood pressure can be assessed to test for sexual impairment. Structure The homologous artery in the female is the dorsal artery of clitoris. Origin The dorsal artery of the penis is a terminal branch of the internal pudendal artery, arising at the inferior border of the symphysis pubis. Course and relations It ...

Bulb Of Penis
The bulb of penis is the proximal/posterior bulged end of the (unpaired median) corpus spongiosum penis. Together with the two crura (one crus on each side of the bulb), it constitutes the root of the penis. It is covered by the bulbospongiosus. Proximally/posteriorly, the bulb of penis extends towards the perineal body The perineum (: perineums or perinea) in placental mammals is the space between the anus and the genitals. The human perineum is between the anus and scrotum in the male or between the anus and vulva in the female. The perineum is the regio .... The bulb exhibits a slight yet palpable midline notch upon its inferior aspect. The male urethra enters the penis at the superior aspect of the anterior part of the bulb (most of the bulb is thus situated inferoposteriorly to the urethra), and the arteries of bulb of penis enter near the urethra. The bulb of penis is homologous to the vestibular bulbs in females. Additional images File:Gray1142.png, Male ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bulb Of Vestibule
In female anatomy, the vestibular bulbs, bulbs of the vestibule or clitoral bulbs are two elongated masses of erectile tissue typically described as being situated on either side of the vaginal opening. They are united to each other in front by a narrow median band. Some research indicates that they do not surround the vaginal opening, and are more closely related to the clitoris than to the vestibule. They constitute the root of the clitoris along with the crura. Structure Research indicates that the vestibular bulbs are more closely related to the clitoris than to the vestibule because of the similarity of the trabecular and erectile tissue within the clitoris and bulbs, and the absence of trabecular tissue in other genital organs, with the erectile tissue's trabecular nature allowing engorgement and expansion during sexual arousal. Ginger et al. state that although a number of texts report that they surround the vaginal opening, this does not appear to be the case and tunica ...

Artery Of Bulb Of Penis
The artery of bulb of penis (artery of the urethral bulb or bulbourethral artery) is a short artery of large caliber which arises from the internal pudendal artery between the two layers of fascia (the superior and inferior) of the urogenital diaphragm. It passes medialward, pierces the inferior fascia of the urogenital diaphragm and gives off branches which ramify in the bulb of the urethra and in the posterior part of the corpus spongiosum The corpus spongiosum is the mass of spongy tissue surrounding the male urethra within the penis. It is also called the corpus cavernosum urethrae in older texts. Structure The proximal part of the corpus spongiosum is expanded to form the ....

Transversus Perinei Superficialis Muscle
The transverse perineal muscles (transversus perinei) are the superficial and the deep transverse perineal muscles. Superficial transverse perineal The superficial transverse perineal muscle (transversus superficialis perinei or Lloyd-Beanie muscle) is a narrow muscular slip, which passes more or less transversely across the perineal space in front of the anus. It arises by tendinous fibers from the inner and forepart of the ischial tuberosity and, running medially, is inserted into the central tendinous point of the perineum (perineal body), joining in this situation with the muscle of the opposite side, with the external anal sphincter muscle behind, and with the bulbospongiosus muscle in front. In some cases, the fibers of the deeper layer of the external anal sphincter cross over in front of the anus and are continued into this mu ...

Perineal Artery
The perineal artery (superficial perineal artery) arises from the internal pudendal artery, and turns upward, crossing either over or under the superficial transverse perineal muscle, and runs forward, parallel to the pubic arch, in the interspace between the bulbospongiosus and ischiocavernosus muscles, both of which it supplies, and finally divides into several posterior scrotal branches which are distributed to the skin and dartos tunic of the scrotum. As it crosses the superficial transverse perineal muscle it gives off the ''transverse perineal artery'' which runs transversely on the cutaneous surface of the muscle, and anastomoses with the corresponding vessel of the opposite side and with the perineal and inferior hemorrhoidal arteries. It supplies the transverse perineal muscles and the structures between the anus In mammals, invertebrates and most fish, the anus (: anuses or ani; from Latin, 'ring' or 'circle') is the external body orifice at the ''exit'' end ...
