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] |
Pelvic Muscles (Female Side)
The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and ...

Anal Triangle
The anal triangle is the posterior part of the perineum. It contains the anus in mammals. Structure The anal triangle can be defined either by its vertices or its sides. * ''Vertices'' ** one vertex at the coccyx bone ** the two ischial tuberosities of the pelvic bone * ''Sides'' ** perineal membrane (posterior border of perineal membrane forms anterior border of anal triangle) ** the two sacrotuberous ligaments Contents Some components of the anal triangle include:Daftary, Shirish; Chakravarti, Sudip (2011).

Rectocele
In gynecology, a rectocele ( ) or posterior vaginal wall prolapse results when the rectum bulges ( herniates) into the vagina. Two common causes of this defect are childbirth and hysterectomy. Rectocele also tends to occur with other forms of pelvic organ prolapse, such as enterocele, sigmoidocele and cystocele. Although the term applies most often to this condition in females, males can also develop it. Rectoceles in men are uncommon, and associated with prostatectomy. Signs and symptoms Mild cases may simply produce a sense of pressure or protrusion within the vagina, and the occasional feeling that the rectum has not been completely emptied after a bowel movement. Moderate cases may involve difficulty passing stool (because the attempt to evacuate pushes the stool into the rectocele instead of out through the anus), discomfort or pain during evacuation or intercourse, constipation, and a general sensation that something is "falling down" or "falling out" within the p ...

Enterocele
An enterocele is a herniation of a peritoneum-lined sac containing small intestine through the pelvic floor, between the rectum and the vagina (in females). Enterocele is significantly more common in females, especially after hysterectomy. It has been suggested that the terms enterocele and sigmoidocele are inaccurate, since hernias are usually named according to location and not according to contents. However, the terms are in widespread use. As such, enterocele, peritoneocele, sigmoidocele, and omentocele could be considered as types of cul-de-sac hernia. Classification * Posterior enterocele (develops in the rectovaginal space, also termed the pouch of Douglas or the cul-de-sac). * Anterior enterocele (develops in the vesicovaginal space). ** Retains the full thickness of the anterior vaginal wall. ** Lacks vaginal wall (or very thin and ulcerated vaginal wall). Anterior enterocele is rare. It may occur after cystectomy or hysterectomy. In these cases, the anterior wall of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urethrocele
A urethrocele is the prolapse of the female urethra into the vagina. Weakening of the tissues that hold the urethra in place may cause it to protrude into the vagina. Urethroceles often occur with cystoceles (involving the urinary bladder as well as the urethra). In this case, the term used is cystourethrocele. Signs and symptoms There are often no symptoms associated with a urethrocele. When present, symptoms include stress incontinence, increased urinary frequency, and urinary retention (difficulty in emptying the bladder). Pain during sexual intercourse may also occur. Complications Where a urethrocele causes difficulty in urinating, this can lead to cystitis. Cause Urethroceles can often result as a result of damage to the supporting structures of the pelvic floor. Urethroceles can form after treatment for gynecological cancers. Urethroceles are often caused by childbirth, the movement of the baby through the vagina causing damage to the surrounding tissues. When they occur i ...

Cystocele
A cystocele, also known as a prolapsed bladder, is a medical condition in which a woman's bladder bulges into her vagina. Some may have no symptoms. Others may have trouble starting urination, urinary incontinence, or frequent urination. Complications may include recurrent urinary tract infections and urinary retention. Cystocele and a prolapsed urethra often occur together and is called a cystourethrocele. Cystocele can negatively affect quality of life. Causes include childbirth, constipation, chronic cough, heavy lifting, hysterectomy, genetics, and being overweight. The underlying mechanism involves weakening of muscles and connective tissue between the bladder and vagina. Diagnosis is often based on symptoms and examination. If the cystocele causes few symptoms, avoiding heavy lifting or straining may be all that is recommended. In those with more significant symptoms a vaginal pessary, pelvic muscle exercises, or surgery may be recommended. The type of surgery typical ...

1116 Muscle Of The Male Perineum
Year 1116 ( MCXVI) was a leap year starting on Saturday of the Julian calendar. Events By place Byzantine Empire * Autumn – Battle of Philomelion: Emperor Alexios I Komnenos leads an expedition into Anatolia and meets the Seljuk army under Sultan Malik Shah (near Philomelium). The Byzantines introduce a new battle formation of Alexios' devising, the ''parataxis'' (a defensive formation, consisting of a hollow square, with the baggage in the centre). During the battle, the Seljuk Turks mount several attacks on the formations, but all are repulsed. The Byzantine cavalry makes two counterattacks; the first is unsuccessful. But a second attack, led by Nikephoros Bryennios the Younger, breaks the Seljuk forces, who then turn to flight. The following day Malik Shah again attacks, his army completely surrounding the Byzantines from all sides. The Seljuk Turks are once more repulsed, with many losses.

Human Anus
In humans, the anus (: anuses or ani; from Latin ''ānus'', "ring", "circle") is the external opening of the rectum located inside the intergluteal cleft. Two sphincters control the exit of Human feces, feces from the body during an act of defecation, which is the primary function of the anus. These are the internal anal sphincter and the external anal sphincter, which are circular muscles that normally maintain constriction of the orifice and which relax as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. Above the anus is the perineum, which is also located beneath the vulva or scrotum. In part owing to its exposure to feces, a number of medical conditions may affect the anus, such as hemorrhoids. The anus is the site of potential infections and other conditions, including cancer (see anal cancer). With anal sex, the anus can play a role in Human sexuality, sexuality. Attitudes toward anal sex vary, and it is illeg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urethral Sphincter
The urethral sphincters are two muscles used to control the exit of urine in the urinary bladder through the urethra. The two muscles are either the external sphincter muscle of male urethra, male or external sphincter muscle of female urethra, female external urethral sphincter and the internal urethral sphincter. When either of these muscles contracts, the urethra is sealed shut. The external urethral sphincter originates at the ischiopubic ramus and inserts into the intermeshing muscle fibers from the other side. It is controlled by the deep perineal branch of the pudendal nerve. Activity in the nerve fibers constricts the urethra. * The internal sphincter muscle of urethra: located at the bladder's inferior end and the urethra's proximal end at the junction of the urethra with the urinary bladder. The internal sphincter is a continuation of the detrusor muscle and is made of smooth muscle, therefore it is under Smooth muscle tissue, involuntary or autonomic nervous system, a ...

Uterus
The uterus (from Latin ''uterus'', : uteri or uteruses) or womb () is the hollow organ, organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic development, embryonic and prenatal development, fetal development of one or more Fertilized egg, fertilized eggs until birth. The uterus is a hormone-responsive sex organ that contains uterine gland, glands in its endometrium, lining that secrete uterine milk for embryonic nourishment. (The term ''uterus'' is also applied to analogous structures in some non-mammalian animals.) In humans, the lower end of the uterus is a narrow part known as the Uterine isthmus, isthmus that connects to the cervix, the anterior gateway leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes at the uterine horns; the rounded part, the fundus, is above the openings to the fallopian tubes. The connection of the uterine cavity with a fallopian tube is called the utero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
