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. Addition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Penis
In Human body, human anatomy, the penis (; : penises or penes; from the Latin ''pēnis'', initially 'tail') is an external sex organ (intromittent organ) through which males urination, urinate and ejaculation, ejaculate, as Penis, on other animals. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system. The main parts of the penis are the Root of penis, root, Body of penis, body, the epithelium of the penis, including the shaft skin, and the foreskin covering the glans penis, glans. The body of the penis is made up of three columns of tissue (biology), tissue: two Corpus cavernosum penis, corpora cavernosa on the dorsal side and corpus spongiosum penis, corpus spongiosum between them on the ventral side. The Urethra#Male, urethra passes through the prostate gland, where it is joined by the ejaculatory ducts, and then through the penis. The urethra goes across the corpus spongiosum and ends at the tip of the glans as the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, retinaculum, retinacula, joint capsules, and septum, 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 D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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
In most terrestrial mammals, the scrotum (: scrotums or scrota; possibly from Latin ''scortum'', meaning "hide" or "skin") or scrotal sac is a part of the external male genitalia located at the base of the penis. It consists of a sac of skin containing the external spermatic fascia, testicles, epididymides, and vasa deferentia. The scrotum will usually tighten when exposed to cold temperatures. The scrotum is homologous to the labia majora in females. Structure In regards to humans, the scrotum is a suspended two-chambered sac of skin and muscular tissue containing the testicles and the lower part of the spermatic cords. It is located behind the penis and above the perineum. The perineal raphe is a small, vertical ridge of skin that expands from the anus and runs through the middle of the scrotum front to back. The scrotum is also a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and ...

Suspensory Ligament Of The Penis
The suspensory ligament of the penis is a triangular midline structure anchoring the penis to the pubic symphysis, holding the penis close to the pubic bone and supporting it during erection. 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. Anatomy Structure The ligament is composed of a midline lamina, and two lateral laminae. Some of the fibres of the ligament come to constitute the fundiform ligament of the penis, extending into the scrotal septum. Attachments The ligament attaches by its apex onto the symphysis pubis and linea alba, and by its base onto the dorsal and lateral aspects of the corpora cavernosa penis. The midline lamina splits inferiorly/distally to attach onto each corpus cavernosus penis lateral to the groove of the deep dorsal vein of penis, whereas each ...

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 or clitoris. It is continuous anteriorly with the deep investing fascia of the abdominal wall muscles, and in males, it is continuous with 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.

Tunica Albuginea (penis)
The tunica albuginea is the fibrous envelope that extends the length of the corpus cavernosum penis and corpus spongiosum penis. It is a bi-layered structure that includes an outer longitudinal layer and an inner circular layer. Structure Microstructure 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 formed partly of unstriped muscular fibers, and a layer of the same tissue immediately surrounds the canal of the urethra. It consists of approximately 5% elastin, with the remainder mostly consisting of collagen. Function 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 stat ...

Superficial Dorsal Veins Of The Penis
In human male anatomy, the dorsal veins of the penis are blood vessels that drain the shaft ( corpora cavernosa, corpus spongiosum), the skin and the glans of the human penis. They are typically located in the midline on the dorsal aspect of the penis and they comprise the superficial dorsal vein of the penis, that lies in the subcutaneous tissue of the shaft, and the deep dorsal vein of the penis, that lies beneath the deep fascia. Superficial dorsal vein The ''superficial dorsal vein of the penis'' belongs to the superficial drainage system. It is located within the superficial dartos fascia, a continuation of the Colles' fascia, on the dorsal surface of the penis and, in contrast to the deep dorsal vein, it lies outside the deeper Buck's fascia. It is formed by smaller superficial veins that merge on the dorsolateral aspect of the penis. It drains the prepuce and the skin of the shaft, and, running backward in the subcutaneous tissue, inclines to the right or left, and ope ...

Dartos Fascia
The dartos fascia, dartos tunic or simply dartos is a layer of connective tissue found in the penile shaft, foreskin and scrotum. 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 arr ... [...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] |
