Scrotal Septum
The septum of the scrotum is a vertical layer of fibrous tissue that divides the two compartments of the scrotum. It consists of flexible connective tissue. Its structure extends to the skin surface of the scrotum as the scrotal raphe. It is an incomplete wall of connective tissue and nonstriated muscle (dartos fascia) dividing the scrotum into two sacs, each containing a testis. Histological septa are seen throughout most tissues of the body, particularly where they are needed to stiffen soft cellular tissue, and they also provide planes of ingress for small blood vessels. Because the dense collagen fibres of a septum usually extend out into the softer adjacent tissues. A septum is a cross-wall. Thus it divides a structure into smaller parts. The scrotal septum is used in reconstructive surgery to restore tissue and or reproductive organs injured or severed by trauma.Male Sexual Dysfunction: Pathophysiology and Treatment, edited by Fouad R.

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...

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] |
Connective Tissue
Connective tissue is one of the four primary types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesenchyme derived from the mesoderm the middle embryonic germ layer. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three meninges, membranes that envelop the brain and spinal cord are composed of connective tissue. Most types of connective tissue consists of three main components: elastic and collagen fibers, ground substance, and cells. Blood, and lymph are classed as specialized fluid connective tissues that do not contain fiber. All are immersed in the body water. The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes. The term "connective tissue" (in German, ''Bindegewebe'') was introduced in 1830 by Johannes Peter Müller. The tissue was already recognized as a distinct class in the 18th century. ...

Sebileau's Muscle
Sebileau's muscle is the deep muscle fibres of the dartos tunic which pass into the scrotal septum. It is named after French anatomist Pierre Sebileau Pierre Sebileau (18 October 1860 – 4 October 1953) was a French surgeon born in Saint-Fort-sur-Gironde, a commune in Charente-Maritime. He was father-in-law to plastic surgeon Léon Dufourmentel (1884–1957). He served as an interne in hosp ... (1860–1953). References Muscles of the torso Scrotum Connective tissue {{Muscle-stub ...

Pierre Sebileau
Pierre Sebileau (18 October 1860 – 4 October 1953) was a French surgeon born in Saint-Fort-sur-Gironde, a commune in Charente-Maritime. He was father-in-law to plastic surgeon Léon Dufourmentel (1884–1957). He served as an interne in hospitals of Bordeaux (from 1879) and Paris (from 1884), where he later worked as an anatomical prosector (1888). Subsequently, he became a surgeon at Hôpital Lariboisière, specializing in the field of otorhinolaryngology. In 1893, he became an associate to the Faculty of Medicine in Paris. In addition to his work with ear, nose and throat concerns, Sebileau made contributions in his investigations involving diseases of the genitourinary system and the kidneys. His name is associated with "Sebileau's muscle", described as deep fibres of the dartos tunic which pass into the scrotal septum.

Perineal Raphe
The perineal raphe is a visible line or ridge of tissue on the body that extends from the anus through the perineum to scrotum (male) or labia majora (female). It is found in both males and females, arises from the fusion of the urogenital folds, and is visible running medial through anteroposterior, to the anus where it resolves in a small knot of skin of varying size. In males, this structure continues through the midline of the scrotum (scrotal raphe) and upwards through the posterior midline aspect of the penis (penile raphe). It also exists deeper through the scrotum where it is called the scrotal septum. It is the result of a fetal developmental phenomenon whereby the scrotum and penis close toward the midline and fuse. See also * Raphe * Linea nigra * Embryonic and prenatal development of the male reproductive system in humans * Frenulum of prepuce of penis The frenulum of prepuce of penis, often known simply as the frenulum, is a highly erogenous elastic band of tissu ...

Linea Nigra
Linea nigra (Latin for "black line"), often referred to as a pregnancy line, is a linear hyperpigmentation that commonly appears on the abdomen. The brownish streak is usually about a centimeter (0.4 in) in width. The line runs vertically along the midline of the abdomen from the pubis to the umbilicus, but can also run from the pubis to the top of the abdomen. For pregnant women, linea nigra is attributed to increased melanocyte-stimulating hormone made by the placenta, which also causes melasma and darkened nipples. Fair-skinned women show this phenomenon less often than women with darker pigmentation. Linea nigra typically disappears within a few months after delivery. Although linea nigra is rarely discussed outside pregnancy, males and females of all ages may have it. Except in pregnancy, both sexes have highest and equal prevalence of linea nigra from age 11 to 15. This increase in prevalence could be the result of hormonal changes during puberty. After age 15, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
