Fascia Of Colles
The membranous layer of the superficial fascia of the perineum (Colles' fascia) is the deeper layer (membranous layer) of the superficial perineal fascia. It is thin, aponeurotic in structure, and of considerable strength, serving to bind down the muscles of the root of the penis. Colles' fascia emerges from the perineal membrane, which divides the base of the penis from the prostate. Colles' fascia emerges from the inferior side of the perineal membrane and continues along the ventral (inferior) penis without covering the scrotum. It separates the skin and subcutaneous fat from the superficial perineal pouch. Relations ''In front'', it is continuous with the dartos fascia of the penis and Scarpa's fascia upon the anterior wall of the abdomen; ''On either side'' it is firmly attached to the margins of the rami of the pubis and ischium, lateral to the crus penis and as far back as the tuberosity of the ischium. ''Posteriorly'', it curves around the superficial transverse perine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Membranous Layer
The membranous layer or stratum membranosum is the deepest layer of subcutaneous tissue. It is a fusion of fibres into a homogeneous layer below the adipose tissue, for example, superficial to muscular fascias. It is considered a fascia by some sources, but not by others. However, prominent areas of the membranous layer are called fascias; these include the fascia of Scarpa in the abdomen and the fascia of Colles in the perineum.

Scarpa's Fascia
The fascia of Scarpa is the deep membranous layer ''(stratum membranosum)'' of the superficial fascia of the abdomen. It is a layer of the anterior abdominal wall. It is found ''deep'' to the fascia of Camper and ''superficial'' to the external oblique muscle. Structure It is thinner and more membranous in character than the superficial fascia of Camper, and contains a considerable quantity of orange elastic fibers. It is loosely connected by areolar tissue to the aponeurosis of the external oblique muscle, but in the midline it is more intimately adherent to the linea alba and the pubic symphysis, and is prolonged on to the dorsum of the penis, forming the fundiform ligament; above, it is continuous with the superficial fascia over the rest of the trunk; inferiorly, it is continuous with the fascia of Colles of the perineum; however, it does not extend into the thigh as it just attaches to its fascia, which is known as fascia lata; medially and below, it is continued over the ...

Superficial Fascia
A fascia (; plural fasciae or fascias; adjective fascial; from Latin: "band") is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs. Fascia is classified by layer, as superficial fascia, deep fascia, and ''visceral'' or ''parietal'' fascia, or by its function and anatomical location. Like ligaments, aponeuroses, and tendons, fascia is made up of fibrous connective tissue containing closely packed bundles of collagen fibers oriented in a wavy pattern parallel to the direction of pull. Fascia is consequently flexible and able to resist great unidirectional tension forces until the wavy pattern of fibers has been straightened out by the pulling force. These collagen fibers are produced by fibroblasts located within the fascia. Fasciae are similar to ligaments and tendons as they have collagen as their major component. They differ in their location and function: li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Fascia Of The Urogenital Diaphragm
The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane. It is the superior border of the superficial perineal pouch, and the inferior border of the deep perineal pouch. Structure The perineal membrane is triangular in shape. It attaches to both ischiopubic rami of the pelvis. It also attaches to the perineal body. It is about 4 cm. in depth. Its apex is directed forward, and is separated from the arcuate pubic ligament by an oval opening for the transmission of the deep dorsal vein of the penis or the deep dorsal vein of the clitoris. Its lateral margins are attached on either side to the inferior rami of the pubis and ischium, above the crus penis. Its base is directed toward the rectum, and connected to the central tendinous point of the perineum. The base is fused with both the pelvic fascia and Colle's fascia. ...

Superficial Transverse Perineal 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 mus ...

Ischium
The ischium () forms the lower and back region of the (''os coxae''). Situated below the ilium and behind the pubis, it is one of three regions whose fusion creates the . The superior portion of this region forms approximately one-third of the acetabulum. |
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 ...

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 ...

Rami Of The Pubis And Ischium
The ischiopubic ramus is a compound structure consisting of the following two structures: * from the pubis, the inferior pubic ramus * from the ischium, the inferior ramus of the ischium It forms the inferior border of the obturator foramen and serves as part of the origin for the obturator internus and externus muscles. Also, most adductors originate at the ischiopubic ramus.

Anterior Wall Of The Abdomen
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity. The abdominal wall is split into the anterolateral and posterior walls. There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum- which covers the visceral peritoneum below it, the extraperitoneal fat, the transversalis fascia, the internal and external oblique and transversus abdominis aponeurosis, and a layer of fascia, which has different names according to what it covers (e.g., transversalis, psoas fascia). In medical vernacular, the term 'abdominal wall' most commonly refers to the layers composing the anterior abdominal wall which, in addition to the layers mentioned above, includes the three layers of muscle: the transversus abdominis (transverse abdominal muscle), the internal (obliquus internus) and the external obl ...

Dartos Fascia
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] |
Subcutaneous Tissue Of Perineum
The subcutaneous tissue of perineum (or superficial perineal fascia) is a layer of subcutaneous tissue surrounding the region of the perineal body. The superficial fascia of this region consists of two layers, superficial and deep. * The superficial layer is thick, loose, areolar in texture, and contains in its meshes much adipose tissue, the amount of which varies in different subjects. In front, it is continuous with the dartos tunic of the scrotum; behind, with the subcutaneous areolar tissue surrounding the anus; and, on either side, with the same fascia on the inner sides of the thighs. In the middle line, it is adherent to the skin on the raphe and to the deep layer of the superficial fascia. * The deep layer of superficial fascia (fascia of Colles The membranous layer of the superficial fascia of the perineum (Colles' fascia) is the deeper layer (membranous layer) of the superficial perineal fascia.
