Obturator foramen - Greater sciatic foramen/Greater sciatic notch - Lesser sciatic foramen This article is about the skeletal organs. ... The pelvis (pl. ... The Pelvic cavity is a body cavity that is bounded by the bones of the pelvis and which primarily contains reproductive organs. ... For the record label, see Sacrum Torch. ... The coccyx is formed of up to five vertebrae. ... The hip bone (or innominate bone) is a large, flattened, irregularly shaped bone, constricted in the center and expanded above and below. ... The ilium of the pelvis is divisible into two parts, the body and the ala; the separation is indicated on the internal surface by a curved line, the arcuate line, and on the external surface by the margin of the acetabulum. ... For other arcuate lines, see arcuate line. ... The wing of ilium (or ala) is the large expanded portion which bounds the greater pelvis laterally. ... The posterior gluteal line (superior curved line), the shortest of the three gluteal lines, begins at the crest, about 5 cm. ... The anterior gluteal line (middle curved line), the longest of the three gluteal lines, begins at the crest, about 4 cm. ... The inferior gluteal line (inferior curved line), the least distinct of the three gluteal lines, begins in front at the notch on the anterior border, and, curving backward and downward, ends near the middle of the greater sciatic notch. ... The internal surface of the ala is bounded above by the crest, below, by the arcuate line; in front and behind, by the anterior and posterior borders. ... The anterior superior iliac spine (ASIS) is an important landmark of surface anatomy. ... Below the Sartorius notch of the anterior border of the ala of the ilium is the anterior inferior iliac spine, which ends in the upper lip of the acetabulum; it gives attachment to the straight tendon of the Rectus femoris and to the iliofemoral ligament of the hip-joint. ... The posterior border of the ala, shorter than the anterior, also presents two projections separated by a notch, the posterior superior iliac spine and the posterior inferior iliac spine. ... The posterior border of the ala, shorter than the anterior, also presents two projections separated by a notch, the posterior superior iliac spine and the posterior inferior iliac spine. ... Human male pelvis, viewed from front Human female pelvis, viewed from front The pelvis is the bony structure located at the base of the spine (properly known as the caudal end). ... Behind the iliac fossa is a rough surface, divided into two portions, an anterior and a posterior. ... Human male pelvis, viewed from front Human female pelvis, viewed from front The pelvis is the bony structure located at the base of the spine (properly known as the caudal end). ... The body of the ischium enters into and constitutes a little more than two-fifths of the acetabulum. ... From the posterior border of the body of the Ischium there extends backward a thin and pointed triangular eminence, the ischial spine, more or less elongated in different subjects. ... Below the ischial spine is a smaller notch, the lesser sciatic notch; it is smooth, coated in the recent state with cartilage, the surface of which presents two or three ridges corresponding to the subdivisions of the tendon of the Obturator internus, which winds over it. ... The superior ramus of the ischium (descending ramus) projects downward and backward from the body and presents for examination three surfaces: external, internal, and posterior. ... Posteriorly the Superior ramus of the ischium forms a large swelling, the tuberosity of the ischium, which is divided into two portions: a lower, rough, somewhat triangular part, and an upper, smooth, quadrilateral portion. ... The Inferior Ramus of the ischium (ascending ramus) is the thin, flattened part of the ischium, which ascends from the superior ramus, and joins the inferior ramus of the pubis—the junction being indicated in the adult by a raised line. ... The pubis, the anterior part of the hip bone, is divisible into a body, a superior and an inferior ramus. ... The superior pubic ramus extends from the body to the median plane where it articulates with its fellow of the opposite side. ... The upper border of the medial portion of the superior ramus of the pubis presents a prominent tubercle, the pubic tubercle (pubic spine), which projects forward. ... Medial to the pubic tubercle is the pubic crest, which extends from this process to the medial end of the bone. ... The lateral portion of superior ramus of the ischium presents a sharp margin, the obturator crest, which forms part of the circumference of the obturator foramen and affords attachment to the obturator membrane. ... The inferior pubic ramus is thin and flattened. ... The pecten pubis or pectinate line of the pubis is a ridge on the superior ramus of the pubic bone. ... This article is about anatomical region. ... The acetabulum presents below a deep notch, the acetabular notch, which is continuous with a circular non-articular depression, the acetabular fossa, at the bottom of the cavity: this depression is perforated by numerous apertures, and lodges a mass of fat. ... The ischiopubic ramus is a compound structure consisting of the following two structures: from the pubis, the inferior pubic ramus from the ischium, the inferior ramus of the ischium It serves as part of the origin for the Obturator internus muscle. ... This page may meet Wikipedias criteria for speedy deletion. ... The obturator foramen is the hole created by the ischium, ilium, and pubic bones of the pelvis through which nerves and muscles pass. ... The greater sciatic foramen is bounded, in front and above, by the posterior border of the hip bone; behind, by the sacrotuberous ligament; and below, by the sacrospinous ligament. ... The greater sciatic foramen is bounded, in front and above, by the posterior border of the hip bone; behind, by the sacrotuberous ligament; and below, by the sacrospinous ligament. ... An opening between the pelvis and the posterior thigh, the foramen is formed by the sacrotuberous ligament which runs between the sacrum and the ischial tuberosity. ...
