Crus Penis
For their anterior three-fourths the corpora cavernosa penis lie in intimate apposition with one another, but behind they diverge in the form of two tapering processes, known as the crura, which are firmly connected to the ischial rami. Traced from behind forward, each crus begins by a blunt-pointed process in front of 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 pair the sitting bones, is a large swelling posteriorly on the superior ramus of the ischium. It marks ..., along the perineal surface of the conjoined (ischiopubic) ramus. Just before it meets its fellow it presents a slight enlargement, named by Georg Ludwig Kobelt (1804–1857) the bulb of the corpus cavernosum penis. Beyond this point the crus undergoes a constriction and merges into the corpus cavernosum proper, which retains a uniform diameter to its anterior end. Additional image ...

Superficial Inguinal Lymph Nodes
Inguinal lymph nodes are lymph nodes in the human groin. Located in the femoral triangle of the inguinal region, they are grouped into superficial and deep lymph nodes. The superficial have three divisions: the superomedial, superolateral, and inferior superficial. Superficial inguinal lymph nodes * The superficial inguinal lymph nodes are the inguinal lymph nodes that form a chain immediately below the inguinal ligament. They lie deep to the fascia of Camper that overlies the femoral vessels at the medial aspect of the thigh. They are bounded superiorly by the inguinal ligament in the femoral triangle; laterally by the border of the sartorius muscle, and medially by the adductor longus muscle. They are divided into three groups: * inferior – inferior of the saphenous opening of the leg, receive drainage from lower legs * superolateral – on the side of the saphenous opening, receive drainage from the side buttocks and the lower abdominal wall. * superomedial – located at ...

Corpora Cavernosa Penis
A corpus cavernosum penis (singular) (literally "cave-like body" of the penis, plural corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis during an erection. Such a corpus is homologous to the corpus cavernosum clitoridis in the female; the body of the clitoris that contains erectile tissue in a pair of corpora cavernosa with a recognisably similar structure. Anatomy The two corpora cavernosa and corpus spongiosum (also known as the ''corpus cavernosum urethrae'' in older texts and in the adjacent diagram) are three expandable erectile tissues along the length of the penis, which fill with blood during penile erection. The two corpora cavernosa lie along the penis 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 anat ...

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 pair the sitting bones, is a large swelling posteriorly on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet. When sitting, the weight is frequently placed upon the ischial tuberosity. The gluteus maximus provides cover in the upright posture, but leaves it free in the seated position.Platzer (2004), p 236 The distance between a cyclist's ischial tuberosities is one of the factors in the choice of a bicycle saddle. Divisions The tuberosity is divided into two portions: a lower, rough, somewhat triangular part, and an upper, smooth, quadrilateral portion. * The ''lower portion'' is subdivided by a prominent longitudinal ridge, passing from base to apex, into two parts: ** The outer gives attachment to the adductor magnus ** The inner to the sacrotuberous ligament * The ''upper portion'' is subdivided into ...

Georg Ludwig Kobelt
Georg Ludwig Kobelt (March 12, 1804 in Kehl – May 18, 1857) was a German anatomist. He studied medicine at the University of Heidelberg, where he was a student of Friedrich Tiedemann (1781–1861). He received his medical doctorate in 1833, later working as a prosector at Heidelberg. From 1841 he was a prosector at the University of Freiburg, subsequently becoming an associate professor (1844), followed by a full professorship in anatomy a few years later (1847). Kobelt is remembered for his studies in sexual anatomy. In 1844, he published the influential ''Die männlichen und weiblichen Wollust-Organe des Menschen und einiger Säugetiere'' ("The Male and Female Organs of Sexual Arousal in Man and some other Mammals"). Kobelt is credited for providing a comprehensive and accurate description of the function of the clitoris. * ] The eponymous "Kobelt's tubules" are named after him, which are remnants of mesonephric ducts in the paroophoron. These remnants are sometimes referr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulb Of The Corpus Cavernosum Penis
Just before each crus of the penis meets its fellow, it presents a slight enlargement, which Georg Ludwig Kobelt named the bulb of the corpus cavernosum penis. The bulb of penis is also known as the urethral bulb. The bulb is homologous to the vestibular bulbs 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 ... in females. Additional images File:Gray1142.png, Male urethra. File:Gray1158.png, Diagram of the arteries of the penis.

Mammal Male Reproductive System
Most mammals are viviparous, giving birth to live young. However, the five species of monotreme, the platypuses and the echidnas, lay eggs. The monotremes have a sex determination system different from that of most other mammals. In particular, the sex chromosomes of a platypus are more like those of a chicken than those of a therian mammal. The mammary glands of mammals are specialized to produce milk, a liquid used by newborns as their primary source of nutrition. The monotremes branched early from other mammals and do not have the teats seen in most mammals, but they do have mammary glands. The young lick the milk from a mammary patch on the mother's belly. Viviparous mammals are in the subclass Theria; those living today are in the Marsupialia and Placentalia infraclasses. A marsupial has a short gestation period, typically shorter than its estrous cycle, and gives birth to an underdeveloped (altricial) newborn that then undergoes further development; in many species, this ta ...
