Deep Artery Of The Penis

	Deep Artery Of The Penis The deep artery of the penis (artery to the corpus cavernosum) is a small collateral branch of the internal pudendal artery that supplies the corpus cavernosum. The artery enters the crus of penis at the crus' anterior extremity. Anatomy Origin The deep artery of the penis one of the terminal branches of the internal pudendal artery. It arises from the internal pudendal artery posterior to the inferior edge of the symphysis pubis while the internal pudendal artery is situated between the two fasciæ of the urogenital diaphragm (deep perineal pouch). Course and fate It traverses the pelvic floor, then immediately enters the corpus cavernosum penis A corpus cavernosum penis (singular) (from Latin, characterised by "cavities/ hollows" of the penis, : corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis of several animal .... It runs anterior-ward in the center of the corpus cavernosum penis, to whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon]
	Internal Pudendal Artery 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon]
picture info	Penis A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation (zoology), copulation, and through which male placental mammals and marsupials also Urination, urinate. The term ''penis'' applies to many intromittent organs of vertebrates and invertebrates, but not to all. As an example, the intromittent organ of most Cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata, there are morphological variants with specific terminology, such as Hemipenis, hemipenes. Etymology The word "penis" is taken from the Latin word for "Latin profanity#Synonyms and metaphors, tail". Some derive that from Proto-Indo-European language, Indo-European ''pesnis'', and the Greek word πέος = "penis" from Indo-European ''pesos''. Prior to the adoption of the Latin word in English, the penis was referred to as a "yard". The Oxford English Dictionary cites an example of the w ...

	Corpus Cavernosum Penis A corpus cavernosum penis (singular) (from Latin, characterised by "cavities/ hollows" of the penis, : corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis of several animals during an erection. It is homologous to the corpus cavernosum clitoridis in the female. Structure The corpora cavernosa are two expandable erectile tissues along the length of the penis, which fill with blood during penile erection. The two corpora cavernosa lie along the penile shaft, from the pubic bones to the head of the penis, where they join. These formations are made of a sponge-like tissue containing trabeculae, irregular blood-filled spaces lined by endothelium and separated by septum of the penis. The male anatomy has no vestibular bulbs, but instead a corpus spongiosum, a smaller region of erectile tissue along the bottom of the penis, which contains the urethra and forms the glans penis.

	Crus Of Penis The two crura of penis (one crus on each side) constitute the root of penis along with the bulb of penis. The two crura flank the bulb – one to each side of the bulb. Each crus is attached at the angle between the perineal membrane and ischiopubic ramus. The deep artery of the penis enters the anterior portion of the crus. Distally, each crus transitions into either corpus cavernosum of the body of the penis. Structure Each crus represents the tapering, posterior fourth of each corpora cavernosa penis; the two corpora cavernosa are situated alongside each other along the length of the body of penis while the two crura diverge laterally in the root of penis before attaching firmly onto either ischial ramus at their proximal end. Each crus begins proximally as a blunt-pointed process in anterior to the tuberosity of the ischium The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, or as a pai ...

	Urogenital Diaphragm Older texts have asserted the existence of a urogenital diaphragm, also called the triangular ligament, which was described as a layer of the pelvis that separates the deep perineal sac from the upper pelvis, lying between the inferior fascia of the urogenital diaphragm (perineal membrane) and superior fascia of the urogenital diaphragm. While this term is used to refer to a layer of the pelvis that separates the deep perineal sac from the upper pelvis, such a discrete border of the sac probably does not exist. While it has no official entry in Terminologia Anatomica, the term is still used occasionally to describe the muscular components of the deep perineal pouch. The urethra and the vagina, though part of the pouch, are usually said to be passing through the urogenital diaphragm, rather than part of the diaphragm itself. Some researchers still assert that such a diaphragm exists, and the term is still used in the literature. The urethral diaphragm is an anatomic landmark ...

picture info	Arteries Of The Abdomen An artery () is a blood vessel in humans and most other animals that takes oxygenated blood away from the heart in the systemic circulation to one or more parts of the body. Exceptions that carry deoxygenated blood are the pulmonary arteries in the pulmonary circulation that carry blood to the lungs for oxygenation, and the umbilical arteries in the fetal circulation that carry deoxygenated blood to the placenta. It consists of a multi-layered artery wall wrapped into a tube-shaped channel. Arteries contrast with veins, which carry deoxygenated blood back towards the heart; or in the pulmonary and fetal circulations carry oxygenated blood to the lungs and fetus respectively. Structure The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with a microscope. The arterial system of the human body is divided into systemic arteries, carrying blood from the heart to the whole body, and pulmonary arteries, c ...
