Flashcards in Hip Bone (Right side, lateral and medial views) Deck (18)
Right and Left hip bone formation
Formed by the union of the
Illium - Above
Ischium - Bhind
Pubis - Extending forward toward the midline
Location: Rough rounded upper surface of the ilium
Location: Posterior surface of the ilium,
Function: where three powerful gluteal muscles attach
Location: anterior surface of the ilium
Function: where the iliacus muscles, a strong hip flexor is located
Anterior Superiro and Anterior Inferior Spines
Posterior Superior and Posterior Inferior Iliac spines
Auricular Surface of the Ilium
Function: where the rough ear shaped lateral edges of the sacrum unite with the auricular surface of the ilium,
Form the sacroiliac joints.
Function: weight of the body is transmitted to these joints. Has very little movement
Anterior and Posterior sacroiliac ligaments
Reinforce the sacroiliac joints
Location: Sharp projection of bone off the ischium
Function: seperates the greater sciatic notch above from the lesser sciatic notch below.
Ligaments attach here to convert the notches into sciatic foramina
Ramus of Ischium
Location: below the lesser sciatic notch
Location: roughened prominece that is below the sciatic notch and above the ramus of ischium
Function: attachment of the "hamstring" muscles of the thigh
Upper border of the pubic bone
Lateral from the midline, crossed by the spermatic cord as it passes through the inguinal canl
Location: medial side of each pubic bone
Function: forms the symphyis pubis joint in the midline
Covered with hyaline Cartilage with a plug of fibro cartilage in btwn that serves to keep these two bones separated yet forming a nearly immovable joint.
Formed by the pubis and ischium
The obturator membrane attached to the margin of the forament.
Actually sealed by this fibrous membrane, with only a small opening for the passage of small vessels and a nerve.
