	Sphincter ani internus muscle - Wikipedia, the free encyclopedia
		The Sphincter ani internus (or internal anal sphincter) is a muscular ring which surrounds about 2.5 cm.
		of the anal canal; its inferior border is in contact with, but quite separate from, the Sphincter ani externus.
		It helps the Sphincter ani externus to occlude the anal aperture and aids in the expulsion of the feces.

		The muscles within the pelvis may be divided into two groups: (1) the Obturator internus and the Piriformis, which are muscles of the lower extremity, and will be described with these (pages 476 and 477); (2) the Levator ani and the Coccygeus, which together form the pelvic diaphragm and are associated with the pelvic viscera.
		In the female the anterior fibers of the Levator ani descend upon the side of the vagina.
		—The Levator ani is supplied by a branch from the fourth sacral nerve and by a branch which is sometimes derived from the perineal, sometimes from the inferior hemorrhoidal division of the pudendal nerve.

		The longest bone in the body is the femur and the smallest is the stapes bone in the middle ear.
		Occasionally one of these processes deviates a little from the median line — a fact to be remembered in practice, as irregularities of this sort are attendant also on fractures or displacements of the vertebral column.
		On either side of the spinous processes is the vertebral groove formed by the laminae in the cervical and lumbar regions, where it is shallow, and by the laminae and transverse processes in the thoracic region, where it is deep and broad; these grooves lodge the deep muscles of the back.

		In the anatomy of mammals, the diaphragm is a shelf of muscle extending across the bottom of the ribcage.
		It is critically important in respiration: in order to draw air into the lungs, the diaphragm contracts, thus enlarging the thoracic cavity and reducing intra-thoracic pressure.
		(The muscles between the ribs also participate in this enlargement.) When the diaphragm relaxes, air is exhaled by elastic recoil of the lung and the tissues lining the thoracic cavity.
