Not illustrated. 1897 Excerpt: ...interval formed by the union of the Levator ani muscles of each side, and just above the coccygeal attachment of the Sphincter ani, is a small conglobate body about as large as a lentil or a pea, first described by Luschka,1 and named by him the coccygeal gland. Its most obvious connections are with the arteries of the part. Structure.--It consists of a congeries of small arteries with little aneurismal dilatations derived from the middle sacral and freely communicating with each 1 Der Himanhanq und die Steisadriise den Menschen, Berlin, 1800; Anatomte del Menschen, Tubingen, 1864, vol. ii. pt. 2, p.' 187. other. These vessels are enclosed in one or more layers of polyhedral granular cells, and the whole structure is invested in a capsule of connective tissue which sends in trabecuhe, dividing the interior into a number of spaces in which the vessels and cells are contained. Nerves pass into this little body from the sympathetic, but their mode of termination is unknown. Macalister believes the glomerulus of vessels " consists of the condensed and convoluted metameric dorsal arteries of the caudal segments imbedded in tissue which is possibly a small persisting fragment of the neurenteric canal." THE COMMON ILIAC ARTERIES. The abdominal aorta divides into the two common iliac arteries. The bifurcation usually takes place on the left side of the body of the fourth lumbar vertebra. This point corresponds to the left side of the umbilicus, and is on a level with a line drawn from the highest point of one iliac crest to the other. The common iliac arteries are about two inches in length; diverging from the termination of the aorta, they pass downward and outward to the margin of the pelvis, and divide opposite the intervertebral substance, between the...Read Less
