They have a specialized endoplasmic reticulum which stores calcium ions and tubular myofibrils made up of two different myofilaments - thin filament (actin) and thick filament. A fat pad in the acetabular fossa is covered with synovial membrane. 63, 66, 67, 78, 80, 81 Generally, European-Americans tend to exhibit such nonmetric dimorphism in the anterior dentition, while African-Americans exhibit nonmetric variation more frequently in the posterior dentition.

Mesovarium, which supports the ovaries. The lateral surface of the ilium has 3 rough curved lines: the posterior, anterior, and inferior gluteal lines.
Retinacula, which contain blood vessels, are deep longitudinal fibers of the capsule that go superiorly from the femoral neck and blend with the periosteum. Mesosalpinx, which supports the fallopian tubes. The fallopian tubes connect each ovary to the uterus. The posterosuperior aspect of the superior ramus of the pubis is called the pectin pubis. ANSI/ADA Specification No. Pelvic organ prolapse occurs when the muscles in the pelvis can no longer support its organs, such as the bladder, uterus, or rectum.
Attached to the margin of the acetabulum is a fibrocartilaginous collar called the acetabular labrum. The deeper circular fibers form a collar around the femoral neck, the zona orbicularis (orbicular zone or annular ligament) and have no bony attachments. Lateral femoral cutaneous. Human premolars and molars exhibit distinctly low, rounded cusps representative of omnivory as opposed to the high crests of herbivores and sharp, conical cusps of carnivores. The pubis bone of each hip bone connects to the other at a joint called the pubis symphysis. The stage of epiphyseal union of long bones is useful in estimating age of persons under around 28 years of age, although nutritional status, population and sex may affect timing of epiphyseal fusion.

Articular surfaces||Head of femur, lunate surface of acetabulum|. Type||Synovial ball and socket; multiaxial|. This ligament prevents overabduction of the hip joint. Specialized cells in the fallopian tubes use hair-like structures called cilia to help direct eggs from the ovaries toward the uterus. The head and neck are at an angle of 130º (± 7º) to the shaft. Muscles acting on the hip joint. The superior part of the body of the ischium fuses with the pubis and ilium, forming the posteroinferior aspect of the acetabulum. Capsular ligaments are intrinsic ligaments of the joint are three capsular ligaments that play a key role in maintaining the integrity of the joint during various movements: iliofemoral, pubofemoral and ischiofemoral ligaments.
Determining sex: Skeletal elements, particularly the pelvis, skull and long bones, can lend valuable evidence for determining sex (not gender) based on human sexual dimorphism (anatomical variation in shape and size based on biological sex). Determining sex from the adult dentition. The articular surfaces are most congruent when the hip joint is in a partially flexed and abducted position. Its apex attaches to the fovea capitis while its base attaches to the acetabular notch and the transverse acetabular ligament.
