The external anal sphincter (or sphincter ani externus) is an oval tube of skeletal muscle fibers. [1] Distally, it is adherent to the skin surrounding the margin of the anus . [ 2 ] It exhibits a resting state of tonical contraction [ 1 ] and also contracts during the bulbospongiosus reflex .
The pudendal nerve that branches to supply the external anal sphincter also branches to the dorsal nerve of the clitoris and the dorsal nerve of the penis. [14] In addition to nerve endings, pleasure from anal intercourse may be aided by the close proximity between the anus and the prostate for males, and vagina, clitoral legs and anal area for ...
Surgeons noticed that during intersphincteric plane dissection if the internal sphincter was damaged and the anal mucosa breached, failure was common despite meticulous repair. [ 2 ] Researchers of the procedure agree that the LIFT technique may cause some injury to internal sphincter, but theoretically LIFT causes less trauma of the internal ...
Enter: anal fingering, which involves using a finger (or two or five) to penetrate, thrust into, or apply pressure to the anus for the sake of pleasure. According to certified sex educator Alicia ...
The sphincter has a plethora of nerve endings— specifically, the pudendal nerve that branches to supply the external anal sphincter also branches to the dorsal nerve of the clitoris and the ...
The internal anal sphincter forms the walls of the anal canal. The internal anal sphincter is not under voluntary control, and in normal persons it is contracted at all times except when there is a need to defecate. This means that the internal anal sphincter contributes more to the resting tone of the anal canal than the external anal ...
The anal wink, anal reflex, perineal reflex, or anocutaneous reflex is the reflexive contraction of the external anal sphincter upon stroking of the skin around the anus. [ 1 ] A noxious or tactile stimulus will cause a wink contraction of the anal sphincter muscles and also flexion.
This neurological problem can also result in reduced sensation of rectal filling and weakness of the anal sphincter because of weak muscular contraction so can cause stool leakage. [12] In patients with multiple sclerosis, constipation and fecal incontinence often coexist, and they can be acute, chronic or intermittent due to the fluctuating ...
