acetabulum

Examples of acetabulum in the following topics:

• Ischium

  • Situated below the ilium and behind the pubis, the superior portion of this bone forms approximately one third of the acetabulum, which articulates with the femoral head to form the hip joint.
  • Left hip joint, opened by removing the floor of the acetabulum from within the pelvis.

• Ilium

  • These two parts are separated on the superior surface by a curved line known as the arcuate line, and on the inferior surface by the margin of the acetabulum.
  • The body contributes to the formation of the acetabulum, a concave structure where the head of the femur articulates to form the hip joint.

• Pubis

  • The pubic bone forms the anterior region of the pelvis and contributes to the acetabulum, which articulates with the femoral head to form the hip joint.
  • (1) sacrum, (2) ilium, (3) ischium, (4) pubis: 4a-body; 4b-superior ramus; 4c-inferior ramus, (5) pubic symphisis, (6) acetabulum, (7) obturator foramen, (8) coccyx, (red dotted line) linea terminalis.

• Femur (The Thigh)

  • The femur articulates proximally with the acetabulum of the pelvis to form the hip joint, and distally with the tibia and patella to form the knee joint.
  • The femoral head projects medially and superiorly and articulates with the acetabulum of the pelvis to form the hip joint.

• Arthroplasty

  • This would involve replacing both the acetabulum (hip socket) and the head and neck of the femur.

• Classification and Identification of Helminths

  • Trematodes are hermaphroditic and utilize oral suckers, ventral suckers or acetabulum for attachment organs.

• Types of Synovial Joints

  • Hip joint: the ball of the femur head fits in the socket of the acetabulum of the pelvis.
