Anatomical terminology

Anal columns (Columns of Morgagni or less commonly Morgagni's columns) are a number of vertical folds, produced by an infolding of the mucous membrane and some of the muscular tissue in the upper half of the lumen of the anal canal. They are named after Giovanni Battista Morgagni, who has several other eponyms named after him.

<span class="mw-page-title-main">Levator ani</span> Broad, thin muscle group, situated on either side of the pelvis

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.

<span class="mw-page-title-main">Sigmoid colon</span> Section of the large intestine closest to the rectum and anus

The sigmoid colon is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 35–40 centimetres (14–16 in) in length. The loop is typically shaped like a Greek letter sigma (ς) or Latin letter S. This part of the colon normally lies within the pelvis, but due to its freedom of movement it is liable to be displaced into the abdominal cavity.

<span class="mw-page-title-main">Pelvic floor</span> Anatomical structure

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 muscle and coccygeus muscle, and associated connective tissue.

<span class="mw-page-title-main">Anal canal</span> Functional segment of the large intestine

The anal canal is the part that connects the rectum to the anus, located below the level of the pelvic diaphragm. It is located within the anal triangle of the perineum, between the right and left ischioanal fossa. As the final functional segment of the bowel, it functions to regulate release of excrement by two muscular sphincter complexes. The anus is the aperture at the terminal portion of the anal canal.

<span class="mw-page-title-main">External anal sphincter</span> Flat plane of skeletal muscle fibers

The external anal sphincter is an oval tube skeletal muscle fibers. Distally, it is adherent to the skin surrounding the margin of the anus. The sphincter exhibits a resting state of tonical contraction.

<span class="mw-page-title-main">Internal anal sphincter</span> Ring of smooth muscle that surrounds part of the anal canal

The internal anal sphincter, IAS, is a ring of smooth muscle that surrounds about 2.5–4.0 cm of the anal canal. It is about 5 mm thick, and is formed by an aggregation of the smooth (involuntary) circular muscle fibers of the rectum. it terminates distally about 6 mm from the anal orifice.

<span class="mw-page-title-main">Pelvic cavity</span> Body cavity bounded by the pelvic bones

The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet. Its lower boundary is the pelvic floor.

<span class="mw-page-title-main">Superior rectal artery</span>

The superior rectal artery is an artery that descends into the pelvis to supply blood to the rectum.

<span class="mw-page-title-main">Urogenital triangle</span> Anterior part of the perineum

The urogenital triangle is the anterior part of the perineum. In female mammals, it contains the vagina and associated parts of the internal genitalia.

<span class="mw-page-title-main">Anal triangle</span> Posterior part of the perineum

The anal triangle is the posterior part of the perineum. It contains the anal canal.

<span class="mw-page-title-main">Transverse folds of rectum</span>

The transverse folds of rectum are semi-lunar transverse folds of the rectal wall that protrude into the rectum, not the anal canal as that lies below the rectum. Their use seems to be to support the weight of fecal matter, and prevent its urging toward the anus, which would produce a strong urge to defecate. Although the term rectum means straight, these transverse folds overlap each other during the empty state of the intestine to such an extent that, as Houston remarked, they require considerable maneuvering to conduct an instrument along the canal, as often occurs in sigmoidoscopy and colonoscopy.

<span class="mw-page-title-main">Pelvic fascia</span>

The pelvic fasciae are the fascia of the pelvis and can be divided into:

<span class="mw-page-title-main">Anal sinuses</span>

An anal sinus is a furrow formed between any two adjacent anal columns of the anal canal. An anal sinus is limited inferiorly by an anal valve. The anal glands open into the anal sinuses.

<span class="mw-page-title-main">Anal valves</span>

An anal valve is a small horizontal fold uniting the inferior ends of any two adjacent anal columns of the anal canal. An anal valve forms the inferior boundary of an anal sinus. The anal valves demarcate the level of the pectinate line.

<span class="mw-page-title-main">Pectinate line</span> Line dividing the upper two-thirds and the lower third of the anal canal

The pectinate line is a line which divides the upper two-thirds and lower third of the anal canal. Developmentally, this line represents the hindgut-proctodeum junction.

<span class="mw-page-title-main">Rectum</span> Final portion of the large intestine

The rectum is the final straight portion of the large intestine in humans and some other mammals, and the gut in others. The adult human rectum is about 12 centimetres (4.7 in) long, and begins at the rectosigmoid junction at the level of the third sacral vertebra or the sacral promontory depending upon what definition is used. Its diameter is similar to that of the sigmoid colon at its commencement, but it is dilated near its termination, forming the rectal ampulla. It terminates at the level of the anorectal ring or the dentate line, again depending upon which definition is used. In humans, the rectum is followed by the anal canal which is about 4 centimetres (1.6 in) long, before the gastrointestinal tract terminates at the anal verge. The word rectum comes from the Latin rectumintestinum, meaning straight intestine.

<span class="mw-page-title-main">Pelvis</span> Lower part of the trunk of the human body between the abdomen and the thighs

The pelvis is the lower part of the trunk, between the abdomen and the thighs, together with its embedded skeleton.

<span class="mw-page-title-main">Rectococcygeal muscle</span>

The rectococcygeal muscles are two bands of smooth muscle tissue arising from the 2nd and 3rd coccygeal vertebrae, and passing downward and forward to blend with the rectal longitudinal smooth muscle fibers on the posterior wall of the anal canal.

<span class="mw-page-title-main">Vaginal support structures</span> Structures that maintain the position of the vagina within the pelvic cavity

The vaginal support structures are those muscles, bones, ligaments, tendons, membranes and fascia, of the pelvic floor that maintain the position of the vagina within the pelvic cavity and allow the normal functioning of the vagina and other reproductive structures in the female. Defects or injuries to these support structures in the pelvic floor leads to pelvic organ prolapse. Anatomical and congenital variations of vaginal support structures can predispose a woman to further dysfunction and prolapse later in life. The urethra is part of the anterior wall of the vagina and damage to the support structures there can lead to incontinence and urinary retention.

The conjoint longitudinal muscle is a muscle layer in the wall of the anal canal between the internal anal sphincter and external anal sphincter. It is continuous proximally with the longitudinal (outer) smooth muscle layer of the rectum. It receives autonomic innervation in common with the internal anal sphincter.
