Hip Bone Beefcake – Medial or Internal Markings
Hip Bone Medial (Internal) Markings:
Ilium Bone Markings:
or Crest of Ilium (Crista iliaca) is the curved upper ridge of the ilium. It is an zipper signal for the latissimus dorsi, quadratus lumborum, erector spine, iliacus, tensor fasciae latae, and abdominal muscles.
Anterior Superior Iliac Spine
or ASIS (Spina iliaca anterior superior) is a projection from the anterior portion of the iliac crest. The sartorius muscle and inguinal ligament adhere to this elevation.
Anterior Inferior Iliac Spine
or AIIS (Spina iliaca anterior inferior) is a projection below the anterior superior iliac spine that serves as an zipper point for the rectus femoris muscle.
Posterior Superior Iliac Spine
(Spina iliaca posterior superior) is a projection from the posterior of the crest. It is an attachment point for the posterior sacroiliac ligament and multifidus muscle.

Posterior Inferior Iliac Spine
(Spina iliaca posterior inferior) is a curvature found junior to the posterior superior iliac spine. The ii spines are separated by a small notch. A ligament that binds the ilium to the sacrum attaches hither.
(Fossa iliaca) is a broad depression located along the anteromedial surface, junior to the iliac crest. It is an zipper point for the iliacus muscle.
(Tuberositas iliaca) is a roughened area located inferior to the crest and posterior to the iliac fossa. The posterior sacroiliac ligaments and the sacrospinalis and multifidus muscles attach here.
(Facies auricular ossis ilii) is a L-shaped or ear-shaped roughened surface situated inferior to the tuberosity. This area articulates with auricular surface of sacrum to form the sacroiliac joint.
(Linea arcuata) is a curved ridge that forms the inferior boundary of the iliac fossa. It also delinates the boundary between the body and the wing (big expanded portion; ala) of the ilium.
Pubic Bone (Pubis) Markings:
or pubic symphysis (Symphysis pubica; symphysis pubis) is the cartilaginous joint between the two pubic bones
Body of pubis
(Corpus ossis pubis) is the flatten, medial finish of the pubis that lies adjacent to the symphysis.
Inferior pubic ramus
(Ramus junior ossis pubis) is a sparse, apartment extension from the medial pubis that joins the ischial ramus. The adductor brevis, adductor magnus, and gracilis muscles attach along this surface.
Superior pubic ramus
(Ramus superior ossis pubis) is a band of os that runs along the superior attribute of the pubis. Information technology is an attachment point for the pectineus musculus.
(Linea pectinea; pecten ossis pubis) is a sharp ridge that runs along the superior margin of the superior pubic ramus. This surface area, which is likewise chosen the pecten pubis, is an the attachment point for the pectineus muscle.
Pubic crest (Crista pubica) is a short, superiomedial ridge that runs extends horizontally from the symphysis to the pubic tubercle. It is an attachment point for the intestinal muscles.
(Tuberculum pubicum) is a projection from the lateral end of the pubic crest that serves equally an zipper point for the inguinal ligament.
Ischium Os Markings:
(Tuber ischiadicum) is a roughened, curved eminence located at the junction of the posterior and inferior borders of the ischium. It supports the weight of the body when sitting and serves as an zipper point for the sacrotuberous ligament and the hamstring muscles, quadratus femoris muscle, and inferior gemellus muscle.
(Inferior) Ramus of Ischium
(Ramus bone-sis ischii) is an anterior extension from the ischial tuberosity that joins the junior pubic ramus. The adductor magnus and obturator externus muscles attach to this surface.
(Spina ischiadica) is a sharp projection from the posterior margin of the ischium. It is an attachment point for the sacrospinous ligament.
Lesser Sciatic Notch
(Incisura ischiadica minor) is a indentation located beneath the spine. The sacrotuberous and sacrospinous ligaments transform the notch into the lesser sciatic foramen, which allows the obturator internus tendon and nerve, internal pudendal vessels, and pudendal nerve to pass.
Interdivisional Bone Markings:
Greater Sciatic Notch
(Incisura ischiadica major) is a large indentation located below the posterior junior iliac spine. The sacrotuberous and sacrospinous ligaments transform the notch into the greater sciatic foramen, which allows the passage of the performs musculus, 7 nerves (including the sciatic nerve), and 3 sets of blood vessels.
(Foramen obturatum; foramen obturatorium) is a large inductive opening enclosed past the pubic and ischial rami. The foramen, which is mostly covered past a ligamentous membrane, helps decrease the weight of the os coxae. The obturator vessels and nerves pass through a large culvert in the upper portion of the membrane.
Identify the Indentation That is Inferiorolateral to the Auricular Surface
