16589. Anatomical terms of bone. [edit on Wikidata] The ilium (/ ˈɪliəm /) (pl.: ilia) is the uppermost and largest region of the coxal bone, and appears in most vertebrates including mammals and birds, but not bony fish. All reptiles have an ilium except snakes, although some snake species have a tiny bone which is considered to be an ilium.
A fracture of the left iliac wing. The iliac crest has a large amount of red bone marrow, and thus it is the site of bone marrow harvests (from both sides) to collect the stem cells used in bone marrow transplantation. The iliac crest is also considered the best donor site for bone grafting when a large quantity of bone is needed.
Surface anatomy of the back. Posterior superior iliac spine lies in the marking of S2. 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 superior iliac spine serves for the attachment of the ...
1321. FMA. 42826. Anatomical terms of bone. [edit on Wikidata] The wing (ala) of ilium is the large expanded portion of the ilium, the bone which bounds the greater pelvis laterally. It presents for examination two surfaces—an external and an internal—a crest, and two borders—an anterior and a posterior.
Latin. lineae glutaea. Anatomical terms of bone. [edit on Wikidata] The gluteal lines are three curved lines outlined from three bony ridges on the exterior surface of the ilium in the gluteal region. [1] They are the anterior gluteal line; the inferior gluteal line, and the posterior gluteal line. The gluteus minimus, medius, and maximus are ...
The perforate acetabulum is a cup-shaped opening on each side of the pelvic girdle formed where the ischium, ilium, and pubis all meet, and into which the head of the femur inserts. [ 8 ] [ 9 ] The orientation and position of the acetabulum is one of the main morphological traits that caused dinosaurs to walk in an upright posture with their ...
The iliac fossa is bounded above by the iliac crest, and below by the arcuate line. It is bordered in front and behind by the anterior and posterior borders of the ilium. The iliac fossa gives origin to the iliacus muscle. [1] The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal.
63615. Anatomical terms of bone. [edit on Wikidata] The posterior inferior iliac spine (Sweeney's Tubercle) is an anatomical landmark that describes a bony "spine", or projection, at the posterior and inferior surface of the iliac bone. It is one of two such spines on the posterior surface, the other being the posterior superior iliac spine.
