The acetabulum also called the cotyloid cavity, is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint.
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh.
The internal pudendal artery is one of the three pudendal arteries. It branches off the internal iliac artery, and provides blood to the external genitalia.
In vertebrate anatomy, the hip, or coxa(pl.: coxae) in medical terminology, refers to either an anatomical region or a joint on the outer (lateral) side of the pelvis.
The external iliac arteries are two major arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis.
The biceps femoris is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion and is activated by a separate nerve.
The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. It is the largest branch of the lumbar plexus.
The sacrotuberous ligament is situated at the lower and back part of the pelvis. It is flat, and triangular in form; narrower in the middle than at the ends.
The sacrospinous ligament is a thin, triangular ligament in the human pelvis. The base of the ligament is attached to the outer edge of the sacrum and coccyx, and the tip of the ligament attaches to the spine of the ischium, a bony protuberance on the human pelvis. Its fibres are intermingled with the sacrotuberous ligament.
The acetabular fossa is the non-articular depressed region at the centre of the floor of the acetabulum. It is surrounded by the articular lunate surface. The floor of the fossa is formed mostly by the ischium; it is rough and thin. The space of the fossa is continuous inferiorly with the acetabular notch.
The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into an anterior branch and a posterior branch.
The medial circumflex femoral artery is an artery in the upper thigh that arises from the profunda femoris artery. It supplies arterial blood to several muscles in the region, as well as the femoral head and neck.
The suprascapular artery is a branch of the thyrocervical trunk on the neck.
The ovarian artery is an artery that supplies oxygenated blood to the ovary in females. It arises from the abdominal aorta below the renal artery. It can be found within the suspensory ligament of the ovary, anterior to the ovarian vein and ureter.
The acetabular notch is a deep notch in the inferior portion of the rim of the acetabulum. It is bridged by the transverse acetabular ligament, converting it into a foramen. It is continuous with space of the acetabular fossa. The lunate surface of acetabulum is discontinued opposite the notch.
The ischiofemoral ligament consists of a triangular band of strong fibers on the posterior side of the hip joint. It is one of the four ligaments that reinforce the hip joint. It attaches to the posterior surface of the acetabular rim and acetabular labrum, and extends around the circumference of the joint to insert on the anterior aspect of the femur. The ischiofemoral ligament limits the internal rotation and adduction of the hip when it is in a flexed position.
The ligament of the head of the femur is a weak ligament located in the hip joint. It is triangular in shape and somewhat flattened. The ligament is implanted by its apex into the anterosuperior part of the fovea capitis femoris and its base is attached by two bands, one into either side of the acetabular notch, and between these bony attachments it blends with the transverse ligament.
The transverse acetabular ligament bridges the acetabular notch, creating the a foramen. The ligament is one of the sites of attachment of the ligament of head of femur.
The acetabular labrum is a fibrocartilaginous ring which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section.
