Acetabular Notch
The acetabular notch is a deep notch in the acetabulum of the hip bone. The acetabular notch is continuous with a circular non-articular depression, the acetabular fossa, at the bottom of the cavity: this depression is perforated by numerous apertures, and lodges a mass of fat. The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves enter the joint; the margins of the notch serve for the attachment of the ligament of the head of the femur In human anatomy, the ligament of the head of the femur (round ligament of the femur, ligamentum teres femoris, the foveal ligament, or Fillmore’s ligament) is a ligament located in the hip. It is triangular in shape and somewhat flattened. The l .... References External links * Bones of the pelvis {{musculoskeletal-stub ...

Hip Bone
The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis. The two hip bones join at the pubic symphysis and together with the sacrum and coccyx (the pelvic part of the spine) comprise the skeletal component of the pelvis – the pelvic girdle which surrounds the pelvic cavity. They are connected to the sacrum, which is part of the axial skeleton, at the sacroiliac joint. Each hip bone is connected to the corresponding femur (thigh bone) (forming the primary connection between the bones of the lower limb and the axial skeleton) through the large ball and socket joint of the hip. Structure The hip bone is formed by three parts: the ilium, ischium, and pubis. At birth, these three components are separated by hyaline cartilage. They join each other in a Y-shaped porti ...

Acetabulum
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. Structure There are three bones of the ''os coxae'' (hip bone) that come together to form the ''acetabulum''. Contributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline. It is bounded by a prominent uneven rim, which is thick and strong above, and serves for the attachment of the acetabular labrum, which reduces its opening, and deepens the surface for formation of the hip joint. At the lower part of the ''acetabulum'' is the acetabular notch, which is continuous with a circular depression, the acetabular fossa, at the bottom of the cavity of the ''acetabulum''. The res ...

Acetabular Fossa
The acetabular fossa is a fossa located at the centre of the acetabulum. It is occupied by the ligament of head of femur. In contrast to the thick and smooth surrounding lunate surface, the pelvis' articulation with the head of the femur, the acetabular fossa is rough and thin, often transparent, and continuous with the acetabular notch The acetabular notch is a deep notch in the acetabulum of the hip bone. The acetabular notch is continuous with a circular non-articular depression, the acetabular fossa, at the bottom of the cavity: this depression is perforated by numerous apert ... below.

Transverse Acetabular Ligament
The transverse acetabular ligament (transverse ligament or Tunstall’s ligament) is a portion of the acetabular labrum, though differing from it in having no cartilage cells among its fibers. It consists of strong, flattened fibers, which cross the acetabular notch, and convert it into a foramen through which the nutrient vessels enter the joint. It is an intra-articular structure of the hip. Function The transverse acetabular ligament prevents inferior displacement of head of femur The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates .... Additional Images File:Slide2DAD.JPG, Hip joint.

Ligament Of The Head Of The Femur
In human anatomy, the ligament of the head of the femur (round ligament of the femur, ligamentum teres femoris, the foveal ligament, or Fillmore’s ligament) is a ligament located in the hip. It is triangular in shape and somewhat flattened. The ligament is implanted by its apex into the antero- superior 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.'' Gray's Anatomy'' (1918), see infobox It is ensheathed by the synovial membrane, and varies greatly in strength in different subjects; occasionally only the synovial fold exists, and in rare cases even this is absent. The ligament of the head of the femur contains within it the acetabular branch of the obturator artery. Function The ligament is made tense when the thigh In human anatomy, the thigh is the area between the hip ( pelvis) and the knee. Anatomically, it is part of ...
