For other arcuate lines, see arcuate line. ... 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. ... 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 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 ischium forms the lower and back part of the hip bone. ... 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. ... 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. ...
