Pelvis
[q]
Define PELVIC GIRDLE[a]This structure is formed by two bones, the OS COXAE.
[q]
Define os coxa[a]This structure is formed by the fusion of three distinct bones – the ILIUM, ISCHIUM and PUBIS.
[q]
Define Ilium[a]This is the most superior bone of the os coxa.
[q]
Define Ischium[a]This is the inferior, posterior bone of the os coxa.
[q]
Define Pubis[a]This is the most anterior, inferior bone of the os coxa.
[q]
Define Acetabulum[a]This is a very deep socket that articulates with the HEAD OF THE FEMUR to form the ILIOFEMORAL joint.
[q]
Define Obturator Foramen[a]This is the largest foramen in the body, formed by the pubis and the ischium and covered by a membrane and muscles.
[q]
Define Iliac Crest[a]This is the most superior margin of os coxa.
[q]
Define Anterior Superior Iliac Spine: (ASIS)[a]This is the tip at the anterior end of the iliac crest.
[q]
Define Anterior Inferior Iliac Spine[a]This is the lower tip at the anterior end of the iliac crest.
[q]
Define Posterior Superior Iliac Spine[a]This is the superior spine overhanging the sacrum at the posterior end of the iliac crest. Lies just lateral to L5.
[q]
Define Posterior Inferior Iliac Spine[a]This is the inferior spine overhanging the sacrum inferior to the PSIS.
[q]
Define Greater Sciatic Notch[a]This is the huge notch just inferior and lateral to the PIIS. Provides passage for the SCIATIC NERVE.
[q]
Define Iliac Fossa[a]This is the depression on the anterior (medial) surface of the ilium which is filled with the muscle iliacus.
[q]
Define Auricular Surface[a]This articulates with AURICULAR SURFACES of the SACRUM to form the SACROILIAC JOINTS.
[q]
Define Sacrospinous Ligaments[a]Which ligaments run from the sacrum to the spine of the ischium.
[q]
Define Ischial Tuberosity[a]This is the large, rounded prominence of ischium that you usually sit on.
[q]
Define Ischial (a.k.a. Sciatic) Spine[a]This is the bony prominence just inferior to the greater sciatic notch.
[q]
Define Lesser Sciatic Notch[a]This is the notch just inferior to the ischial spine. A muscle passes through this groove (obturator internus)
[q]
Define Symphysis Pubis[a]This is a disk of fibrocartilage that joins the os coxae together. It is between the pubic bodies of both os coxae.
[q]
Define Inferior Ramus[a]This is the portion of the pubis connecting the body to the ischial ramus.
[q]
Define Superior Ramus[a]This is the bony part connecting the body of the pubis to the ilium near the acetabulum.
[q]
Define Pubic Crest[a]This is the anterior, superior edge of the pubic body.
[q]
Define Pubic Tubercle[a]This is the small bump at medial tips of pubic crest.
[q]
PELVIS list the bones[a]This is composed of four bones – two os coxae, sacrum, coccyx.
[q]
Define Anterior Tilt [a]In this condition the ASIS lies anterior to the pubic crest on the coronal plane.
[q]
Define Posterior Tilt [a]In this condition the ASIS lies posterior to the pubic crest on the coronal plane.
[q]
Head of the femur joins with what?[a]This bone articulates with the acetabulum.
[/qdeck]
