Buck's Fascia
Buck's fascia (deep fascia of the penis, Gallaudet's fascia or fascia of the penis) is a layer of deep fascia covering the three erectile bodies of the penis. Structure Buck's fascia is continuous with the external spermatic fascia in the scrotum and the suspensory ligament of the penis. On its ventral aspect, it splits to envelop corpus spongiosum in a separate compartment from the tunica albuginea and corporal bodies. Variation Sources differ on its proximal extent. Some state that it is a ''continuation'' of the deep perineal fascia, whereas others state that it fuses with the tunica albuginea. Function The deep dorsal vein of the penis, the cavernosal veins of the penis, and the para-arterial veins of the penis are inside Buck's fascia, but the superficial dorsal veins of the penis are in the superficial (dartos) fascia immediately under the skin. History Etymology The name Buck's fascia is named after Gurdon Buck, an American plastic surgeon. Additional images ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Penis
The human penis is an external male intromittent organ that additionally serves as the urinary duct. The main parts are the root (radix); the body (corpus); and the epithelium of the penis including the shaft skin and the foreskin (prepuce) covering the glans penis. The body of the penis is made up of three columns of tissue: two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The human male urethra passes through the prostate gland, where it is joined by the ejaculatory duct, and then through the penis. The urethra traverses the corpus spongiosum, and its opening, the meatus (), lies on the tip of the glans penis. It is a passage both for urination and ejaculation of semen (''see'' male reproductive system.) Most of the penis develops from the same embryonic tissue as the clitoris in females. The skin around the penis and the urethra share the same embryonic origin as the labia minora in females. An erection is the stiffening e ...

Deep Fascia
Deep fascia (or investing fascia) is a fascia, a layer of dense connective tissue that can surround individual muscles and groups of muscles to separate into fascial compartments. This fibrous connective tissue interpenetrates and surrounds the muscles, bones, nerves, and blood vessels of the body. It provides connection and communication in the form of aponeuroses, ligaments, tendons, retinacula, joint capsules, and septa. The deep fasciae envelop all bone (periosteum and endosteum); cartilage (perichondrium), and blood vessels (tunica externa) and become specialized in muscles (epimysium, perimysium, and endomysium) and nerves (epineurium, perineurium, and endoneurium). The high density of collagen fibers gives the deep fascia its strength and integrity. The amount of elastin fiber determines how much extensibility and resilience it will have. Examples Examples include: * Fascia lata * Deep fascia of leg * Brachial fascia * Buck's fascia Fascial dynamics Deep fascia is l ...

Penis
A penis (plural ''penises'' or ''penes'' () is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penises in the various species are not necessarily homologous. The term ''penis'' applies to many intromittent organs, 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. In most species of animals in which there is an organ that might reasonably be described as a penis, it has no major function other than intromission, or at least conveying the sperm to the female, but in the Eutheria, placental mammals the peni ...

External Spermatic Fascia
The external spermatic fascia (intercrural or intercolumnar fascia) is a thin membrane, prolonged downward around the surface of the spermatic cord and testis. It is separated from the dartos tunic by loose areolar tissue. It is occasionally referred to as 'Le Fascia de Webster' after an anatomist who once described it. Structure The external spermatic fascia is derived from the aponeurosis of the abdominal external oblique muscle. It is acquired by the spermatic cord at the superficial inguinal ring. References External links * - "The inguinal canal and derivation of the layers of the spermatic cord The spermatic cord is the cord-like structure in males formed by the vas deferens (''ductus deferens'') and surrounding tissue that runs from the deep inguinal ring down to each testicle.

Scrotum
The scrotum or scrotal sac is an anatomical male reproductive structure located at the base of the penis that consists of a suspended dual-chambered sac of skin and smooth muscle. It is present in most terrestrial male mammals. The scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens. It is a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and pampiniform plexus. The perineal raphe is a small, vertical, slightly raised ridge of scrotal skin under which is found the scrotal septum. It appears as a thin longitudinal line that runs front to back over the entire scrotum. In humans and some other mammals the scrotum becomes covered with pubic hair at puberty. The scrotum will usually tighten during penile erection and when exposed to cold temperatures. One testis is typically lower than the other to avoid compression in the event of an impact. The scrotum is biologicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspensory Ligament Of The Penis
The suspensory ligament of the penis is attached to the pubic symphysis, which holds the penis close to the pubic bone and supports it when erect. The ligament does not directly connect to the Corpus cavernosum penis, but may still play a role in erectile dysfunction. The ligament can be surgically lengthened in a procedure known as ligamentolysis, which is a form of penis enlargement. Gallery File:Slide4Nemo.JPG, Anterior abdominal wall. Intermediate dissection.

Deep Perineal Fascia
The fascia of perineum (deep perineal fascia, superficial investing fascia of perineum or Gallaudet fascia) is the fascia which covers the muscles of the superficial perineal pouch. The muscles surrounded by the deep perineal fascia are the bulbospongiosus, ischiocavernosus, and superficial transverse perineal. The fascia is attached laterally to the ischiopubic rami and fused anteriorly with the suspensory ligament of the penis The suspensory ligament of the penis is attached to the pubic symphysis, which holds the penis close to the pubic bone and supports it when erect.

Tunica Albuginea (penis)
The tunica albuginea is the fibrous envelope that extends the length of the corpora cavernosa penis (containing erectile tissue) and corpus spongiosum penis (containing the male urethra). It is a bi-layered structure that includes an outer longitudinal layer and an inner circular layer. It consists of approximately 5% elastin, with the remainder mostly consisting of collagen. The tunica albuginea is directly involved in maintaining an erection; that is due to Buck's fascia constricting the erection veins of the penis, preventing blood from leaving and thus sustaining the erect state. The erection veins include the deep dorsal vein, two cavernosal veins, and four para-arterial veins. The trabeculae of the tunica albuginea are more delicate, nearly uniform in size, and the meshes between them smaller than in the corpora cavernosa penis: their long diameters, for the most part, corresponding with that of the penis. The external envelope or outer coat of the corpus spongiosum is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Superficial Dorsal Veins Of The Penis
In human anatomy, the dorsal veins of the penis comprise the superficial dorsal vein of the penis and the deep dorsal vein of the penis. Superficial dorsal vein The ''superficial dorsal vein of the penis'' drains the prepuce and skin of the penis, and, running backward in the subcutaneous tissue, inclines to the right or left, and opens into the corresponding superficial external pudendal vein, a tributary of the great saphenous vein. In contrast to the deep dorsal vein, it lies ''outside'' Buck's fascia. It is possible for the vein to rupture, which presents in a manner similar to penile fracture. Deep dorsal vein The ''deep dorsal vein of the penis'' lies beneath the deep fascia of the penis; it receives the blood from the glans penis and corpora cavernosa penis and courses backward in the middle line between the dorsal arteries; near the root of the penis it passes between the two parts of the suspensory ligament and then through an aperture between the arcuate pubic ...

Dartos
The dartos fascia or simply dartos is a layer of connective tissue found in the penile shaft, foreskin, scrotum and labia. The penile portion is referred to as the superficial fascia of penis or the subcutaneous tissue of penis, while the scrotal part is the dartos proper. In addition to being continuous with itself between the scrotum and the penis, it is also continuous with Colles fascia of the perineum and Scarpa's fascia of the abdomen. The dartos lies just below the skin, which places it just superficial to the external spermatic fascia in the scrotum and to Buck's fascia in the penile shaft. In the scrotum, it consists mostly of smooth muscle. The tone of this smooth muscle is responsible for the wrinkled (rugose) appearance of the scrotum. In females, the same muscle fibers are less well developed and termed ''dartos muliebris,'' lying beneath the skin of the labia majora. The dartos fascia receives innervation from postganglionic sympathetic nerve fibers arriving via the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gurdon Buck
Gurdon Buck (May 4, 1807 – March 6, 1877) was a pioneering military plastic surgeon during the Civil War. He is known for being the first doctor to incorporate pre- and post-operative photographs into his publications. Buck's fascia and Buck's extension are both named after him. Biography Education Buck graduated from the Columbia University College of Physicians and Surgeons in 1830 and interned at New York Hospital. He also studied in Paris, Berlin and Vienna. He was appointed visiting surgeon to the New York Hospital in 1837 which he held the rest of his life. He was also appointed to the New York Eye and Ear Infirmary. Advances in medicine In 1845, Buck took the first clinical photograph and used an engraving of it in "The Knee Joint Anchylosed at a Right Angle". This was the first known published illustration of a medical photograph. Dr. Buck was a founding fellow of The New York Academy of Medicine in 1847. He wrote ''Contributions to Reparative Surgery'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
