	Hemorrhoid.net - Anal Fissure
		An anal fissure (AY-nul FISH-er) is a tear in the anus causing a painful linear ulcer at the margin of the anus.
		Because of an associated anal crypt infection, causing cryptitis, a fissure, an ulcer, or possibly even an abscess may occur at the superior aspect of the anal canal where it attaches to the lower rectal mucosa.
		Since anal fissures are characterized by spasm of the internal anal sphincter and a reduction in mucosal blood flow, the aim of treatment is to relieve ischemia by reducing resting anal pressure and improving mucosal perfusion.

		For the internal anal sphincters, the needle electrode was introduced 0.5 cm lateral to the anal orifice to a depth of 1.0-1.5 cm.
		The needle electrode for the external anal sphincters was inserted into the muscle 0.75-1.00 cm lateral to the anal orifice and contralateral to the internal anal sphincter’s electrode to a depth of 1.0-1.5 cm.
		Anal sphincteric contraction upon cavernosus muscles’contraction during sexual intercourse presumably acts to close the anal canal to prevent flatus or fecal leak during coitus.

	anal glands
		The anal sacs are normally expressed (emptied) by rectal pressure during defecation.
		This involuntary contraction can be due to the dog being upset, frightened or under pressure, or the contractions can be triggered by the dog to leave its mark upon territory.
		Anal gland impaction is treated by manual emptying of the glands.

	Enemagra UK (Site not responding. Last check: 2007-10-16)
		Since the Enemagra is driven by the anal sphincter's contraction alone, the pressure given to the prostate is safe and adequate, and gradually increases as the exercise progresses.
		The contraction and the relaxation of the anal sphincter muscle is proven to be a good exercise for toning the genitourinary tracts of the human body.
		Because the Enemagra is suspended unstably within the anal canal, the slightest muscular action and even the pulsing of blood vessels infiltrating the anal canal and surrounding the prostate is picked up by the Enemagra and directly reflected upon the anal canal, prostate and the perineum acupressure point.

	Aneros [Instructions]
		Holding this level of contraction is difficult - anal muscles will quiver and may spasm causing a vibration that corresponds to the muscle’s involuntary movements.
		Because the Aneros Massager is suspended unstably within the anal canal, the slightest muscular action and even the pulsing of blood vessels infiltrating the anal canal and surrounding the prostate is detected by the Aneros and directly transmitted to the anal canal, prostate and the perineum acupressure point.
		Gentle anal contraction is more likely to cause anal orgasms, whereas stronger contractions will lead to prostate-generated orgasms or a combination of sensations.

		The anal depressor is a sexually dimorphic muscle, present in both sexes but specialized in the male to function as an auxillary spicule muscle (Sulston et al., 1980; see MUSCLES OF THE MALE - Part I).
		Contraction of the protractors therefore has the opposite affect to retractor contraction and causes the spicules to extrude from the body.
		Contraction of the gubernacular muscles may serve to lift the proctodeal roof, allowing spicules to move more freely or alternatively deflect them towards the cloaca.

	yahooyoga: Horse Gesture
		Contract the sphincter muscles of the anus for a few seconds without straining, then relax them for a few seconds.
		This practice strengthens the anal muscles and alleviates disorders of the rectum such as constipation, piles and prolapsed of the uterus or rectum.
		The practice is so-called because the anal contraction resembles the movement a horse makes with its sphincter immediately after evacuation of the bowels.

	Aneros Detailed Instructions
		Note: This exercise strengthens the anal sphincter and increases the blood circulation to the region.
		Because the Aneros massager is suspended unstably within the anal canal, the slightest muscular action and even the pulsing of blood vessels infiltrating the anal canal and surrounding the prostate is picked up by the Aneros massager and directly reflected upon the anal canal, prostate and the perineum acupressure point.
		As you increase the strength of the contraction, the Aneros massager will be drawn deeper toward the prostate as it moves in a stroking motion with increasing pressure.

		It contracts almost simultaneously with the other two types of enteric muscles to either further squeeze the intestine during expulsion of gut contents to outside or to restrict the outflow.
		Finally by contraction of the enteric muscles the expulsion of gut contents to outside is achieved and the intercycle period starts.
		During larval stages the anal structures of the male is identical to those of the hermaphrodite.

	New study seeks to establish mechanism between areas of the brain and continence
		What is known mostly addresses its contraction response to experimental electrical or magnetic stimulation of the motor cortex, the region of the cerebral cortex most nearly immediately influencing movements of the face, neck and trunk, and arm and leg.
		Past studies have shown that the contracting of the EAS or pelvic floor to direct stimulation of the motor cortex, the cerebral cortical activity map related to voluntary contraction of this sphincter, could be quite different from the cortical topography of its control determined by direct stimulation of the cerebral cortex.
		Stage 2: Self-reported maximum EAS contraction without the presence of a measurement device resulted in changes in cerebral cortical blood oxygenation level in four distinctive areas of the brain, similar to studies conducted with the presence of the manometric device.

	Go Ask Alice!: Anal sex and waste products
		An enema prior to anal sex is not a necessary procedure, and it is uncommon.
		The anal sphincter responds to the initial penetration attempt with a spastic contraction, which is usually felt by the male penetrating the anus.
		Anal bacteria from waste products can be on the penis following anal intercourse, so it is critical to thoroughly clean the penis afterwards, especially before engaging in vaginal intercourse or receiving oral sex.

	Human sexual response cycle - Wikipedia, the free encyclopedia
		During this phase, the male urinary bladder closes (so as to prevent urine from mixing with semen) and muscles at the base of the penis begin a steady rhythmic contraction.
		Both males and females experience quick cycles (typically 0.8 seconds apart) of muscle contraction of the anus and lower pelvic muscles, with women also experiencing uterine and vaginal contractions.
		Males ejaculate approximately 2-5ml of semen, with the volume varying considerably depending on the period of abstinence and degree of sustained arousal prior to ejaculation.

	Proctoptosis
		It is necessary to observe the contraction of the anus and judge the effectiveness of the treatment.
		If the contraction of the anus is fast and when it stops con tract, the anus is not easy pulled apart, it shows that the injection is successful and the fixation is also firm.
		If the contraction the anus is easy to be pulled apart, this shows that the fixation is not firm enough but is still does not prove that the injection is a failure.

		Among the 12 patients with anal atresia, 6 (50 percent) were treated successfully, which is the lowest success rate out of the study, 22 out of 24 patients with incontinence due to trauma (94 percent) had successful outcomes.
		Patients with anal atresia scored very well preoperatively on all questionnaires (with scores similar to those of healthy persons) compared to people who had a short history of incontinence.
		Unfortunately replacing the anal sphincter is not enough of a treatment for the majority of imperforate anus patients.

		Stay with this contraction for several minutes before introducing any harder contractions, just so you can become accustomed to what it feels like (it may feel different later when you return to it from a higher magnitude contraction and you want to be able to recognize that).
		Anal and rectal contractions work antagonistically, one pushing in the other pushing out, very often interesting sensations can be developed by working these techniques simultaneously.
		OR bear down (rectal contraction) with a slight anal contraction while executing some short panting (quick inhalation and exhalation but with very little air exchanged so you are neither hyperventilating or becoming anoxic, while doing this expand your lower abdomen as if filling with air.

	[Frontiers in Bioscience, 4, b9-13, October 1, 1999]
		To investigate the reason why, during a mass contraction, the stool moving from the colon to the sigmoid colon stops short of the rectosigmoid junction (RSJ) instead of passing directly to the rectum, and whether the sigmoid colon and RSJ share in the anorectal continent mechanism, 12 mongrel dogs were studied.
		The EMG activity of the external anal sphincter was studied by means of a concentric needle electrode (Type 13L 49, Disa, Copenhagen, Denmark), 30 mm in length and 0.45 mm in diameter.
		The momentary external anal sphincter contraction upon rectal distension is considered to be a spinal reflex (14,15).

		At the beginning of defecation, the subject voluntarily raises intra-abdominal pressure by muscular contraction of the quadratus lumborum, rectus abdominis, external and internal obliques, transversus abdominis and diaphragm.
		As feces emerges from the anus, the longitudinal muscles of the rectum and levator ani bring the anal canal back up, the feces is expelled, and the anus and rectum rise back up and forward to return to their normal position.
		In the video, when the patient performs the squeeze maneuver, the anal canal can be seen tightly closed between the anorectal junction and the external anal orifice.

		Notably, the internal anal sphincter (IAS) of patients with hemorrhoids demonstrates an abnormal rhythm of contraction and also exerts a greater force of contraction than in individuals without hemorrhoids.
		However, an overactive sphincter might contribute to venous congestion, expose the anal cushions to greater shear forces, or do both by constricting the anal canal.
		Nitroglycerin is known to relax the internal anal sphincter, and smooth muscle in general, by acting as a nitric oxide donor.
