Urogenital Hiatus
The urogenital hiatus is a large midline opening in the anteromedial part of the pelvic floor (more precisely, the Pubococcygeal (PC) muscles, pubococcygeal muscle), extending between the pubis (anteriorly), and rectum (posteriorly). Each Levator ani, levator ani muscle forms either lateral border of the hiatus. The hiatus acccomodates the apex of the prostate in males, and gives passage to the urethra in both sexes, the vagina in females, the deep dorsal vein of clitoris (females) or Deep dorsal vein of penis, penis (males), and nerves of the penis in males. __TOC__ Clinical significance The urogenital hiatus has been linked to urinary stress incontinence.

Pelvic Floor
The pelvic floor or pelvic diaphragm is an anatomical location in the human body which has an important role in urinary and anal continence, sexual function, and support of the pelvic organs. The pelvic floor includes muscles, both skeletal and smooth, ligaments, and fascia and separates between the pelvic cavity from above, and the perineum from below. It is formed by the levator ani, levator ani muscle and coccygeus muscle, and associated connective tissue. The pelvic floor has two hiatus (anatomy), hiatuses (gaps): (anteriorly) the urogenital hiatus through which urethra and vagina pass, and (posteriorly) the rectal hiatus through which the anal canal passes. Structure Definition Some sources do not consider "pelvic floor" and "pelvic diaphragm" to be identical, with the "diaphragm" consisting of only the levator ani and coccygeus, while the "floor" also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pubococcygeal (PC) Muscles
The levator ani is a broad, thin muscle group, situated on either side of the pelvis. It is formed from three muscle components: the pubococcygeus, the iliococcygeus, and the puborectalis. It is attached to the inner surface of each side of the lesser pelvis, and these unite to form the greater part of the pelvic floor. The coccygeus muscle completes the pelvic floor, which is also called the ''pelvic diaphragm''. It supports the viscera in the pelvic cavity, and surrounds the various structures that pass through it. The levator ani is the main pelvic floor muscle and contracts rhythmically during female orgasm, and painfully during vaginismus. Structure The levator ani is made up of 3 parts: * Iliococcygeus muscle * Pubococcygeus muscle * Puborectalis muscle The iliococcygeus arises from the inner side of the ischium (the lower and back part of the hip bone) and from the posterior part of the tendinous arch of the obturator fascia, and is attached to the coccyx and anococcy ...

Urethra
The urethra (: urethras or urethrae) is the tube that connects the urinary bladder to the urinary meatus, through which Placentalia, placental mammals Urination, urinate and Ejaculation, ejaculate. The external urethral sphincter is a striated muscle that allows voluntary control over urination. The Internal urethral sphincter, internal sphincter, formed by the involuntary smooth muscles lining the bladder neck and urethra, receives its nerve supply by the Sympathetic nervous system, sympathetic division of the autonomic nervous system. The internal sphincter is present both in males and females. Structure The urethra is a fibrous and muscular tube which connects the urinary bladder to the external urethral meatus. Its length differs between the sexes, because it passes through the penis in males. Male In the human male, the urethra is on average long and opens at the end of the external urethral meatus. The urethra is divided into four parts in men, named after the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deep Dorsal Vein Of 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 ...

Coccyx
The coccyx (: coccyges or coccyxes), commonly referred to as the tailbone, is the final segment of the vertebral column in all apes, and analogous structures in certain other mammals such as horse anatomy, horses. In tailless primates (e.g. humans and other great apes) since ''Nacholapithecus'' (a Miocene hominoid),Nakatsukasa 2004, ''Acquisition of bipedalism'' (SeFig. 5entitled ''First coccygeal/caudal vertebra in short-tailed or tailless primates.''.) the coccyx is the remnant of a Human vestigiality#Coccyx, vestigial tail. In animals with bony tails, it is known as Rump (animal), ''tailhead'' or ''dock'', in bird anatomy as ''tailfan''. It comprises three to five separate or fused coccygeal vertebrae below the sacrum, attached to the sacrum by a fibrocartilaginous joint, the sacrococcygeal symphysis, which permits limited movement between the sacrum and the coccyx. Structure The coccyx is formed of three, four or five rudimentary vertebrae. It articulates superiorly with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pelvic Floor Dysfunction
Pelvic floor dysfunction is a term used for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. The condition affects up to 50 percent of women who have given birth. Although this condition predominantly affects women, up to 16 percent of men are affected as well. Symptoms can include pelvic pain, pressure, pain during sex, urinary incontinence (UI), overactive bladder, bowel incontinence, incomplete emptying of feces, constipation, myofascial pelvic pain and pelvic organ prolapse. When pelvic organ prolapse occurs, there may be visible organ protrusion or a lump felt in the vagina or anus. Research carried out in the UK has shown that symptoms can restrict everyday life for women. However, many people found it difficult to talk about it and to seek care, as they experienced embarrassment and stigma. Common treatments for pelvic floor dysfunction are surgery, medication, physical therapy and lifestyle modifications. The term "pelvic floor dys ...

Perineology
Perineology is a speciality dealing with the functional troubles of the three axes ( urological, gynaecological and coloproctological) of the female perineum. The perineologist takes a holistic approach, using defect-specific and mini-invasive treatments. History of the term The word perineology represents a neologism. It was invented for the occasion of the 1st International Symposium on Perineology, held in Venice in 1990 to reflect an integrated view of the anatomy, physiology and pathology of the pelvic floor. It was popularized by the Italian journal Rivista Italiana di Colon-Proctologia. Some physicians in France and Italy prefer to use the broader term “pelviperineology”, which reflect a broader multidisciplinary approach to all the aspects of the management of the pelvic floor. In 2010, an International Society for Pelviperineology was formed. References {{reflist External links European Perineology Group - GEPUp to date information about this new speciality by ...

Perineal Hernia
Perineal hernia is a hernia involving the perineum (pelvic floor). The hernia may contain fluid, fat, any part of the intestine, the rectum, or the urinary bladder, bladder. It is known to occur in humans, dogs, and other mammals, and often appears as a sudden swelling to one side (sometimes both sides) of the anus. A common cause of perineal hernia is surgery involving the perineum. Perineal hernia can be caused also by excessive straining to defecate. Atrophy of the levator ani muscle and disease of the pudendal nerve may also contribute to a perineal hernia. In humans In humans, a major cause of perineal hernia is perineal surgery without adequate reconstruction. In some cases, particularly surgeries to remove the coccyx and distal sacrum, adequate reconstruction is very difficult to achieve. The posterior perineum is a preferred point of access for surgery in the pelvic cavity, particularly in the presacral space. Surgeries here include repair of rectal prolapse and anteri ...

Female Genital Prolapse
Pelvic organ prolapse (POP) is characterized by descent of pelvic organs from their normal positions into the vagina. In women, the condition usually occurs when the pelvic floor collapses after gynecological cancer treatment, childbirth or heavy lifting. Injury incurred to fascia membranes and other connective structures can result in cystocele, rectocele or both. Treatment can involve dietary and lifestyle changes, physical therapy, or surgery. Types * Anterior vaginal wall prolapse ** Cystocele (bladder into vagina) ** Urethrocele (urethra into vagina) ** Cystourethrocele (both bladder and urethra) * Posterior vaginal wall prolapse ** Enterocele (small intestine into vagina) ** Rectocele (rectum into vagina) ** Sigmoidocele * Apical vaginal prolapse ** Uterine prolapse (uterus into vagina) ** Vaginal vault prolapse (descent of the roof of vagina) – after surgical removal of the uterus hysterectomy Grading Pelvic organ prolapses are graded either via the Baden–W ...
