What type of joint is Articulatio Coxae?
Coxal Articulation or Hip-joint (Articulatio Coxæ) This articulation is an enarthrodial or ball-and-socket joint, formed by the reception of the head of the femur into the cup-shaped cavity of the acetabulum.
What is pubofemoral ligament?
The pubofemoral ligament is anteroinferior to the hip joint. It is triangular, its base attaching to the iliopubic eminence, superior pubic ramus, obturator crest and obturator membrane. It blends distally with the capsule and deep surface of the medial iliofemoral ligament.
What is the function of the iliofemoral ligament?
The iliofemoral ligament is the strongest ligament in the body and attaches the anterior inferior iliac spine (AIIS) to the intertrochanteric crest of the femur. The pubofemoral ligament prevents excess abduction and extension, ischiofemoral prevents excess extension, and the iliofemoral prevents hyperextension.
What is the name of the joint that connects the os coxae to the sacrum?
The interior-facing side of this “wing” is called the iliac fossa. The ilium is where the sacrum attaches to each coxal bone to complete the pelvic bowl. This attachment point is alternatively called the sacroiliac joint, the sacroiliac articulation, or the iliac tuberosity, and is a rough surface.
Why is the fovea capitis important?
The femoral head is the most proximal portion of the femur and is supported by the femoral neck. It articulates with the acetabulum of the pelvis. The femoral head is nearly spherical (two-thirds) but has a medial depression known as the fovea capitis femoris that serves as an attachment point for the ligamentum teres.
What is the Coracoacromial ligament?
The coracoacromial ligament (CAL) connects the acromion and coracoid process of the scapula, forming an osseoligamentous static restraint to superior humeral head displacement.
What is the zona orbicularis?
The zona orbicularis are circular fibers of the hip joint capsule and form a collar around the femoral neck. Though partly blended with the pubofemoral and ischiofemoral ligaments, these fibers are not directly attached to bone.
Where is iliofemoral?
The iliofemoral ligament is a ligament of the hip joint which extends from the ilium to the femur in front of the joint. It is also referred to as the Y-ligament (see below). the ligament of Bigelow, the ligament of Bertin and any combinations of these names.
What are intracapsular ligaments?
n. Any of the ligaments located within and separate from the articular capsule of a synovial joint.
