Ball and socket joint (also known as enarthrosis or spheriodal joint)
One side of the pubis articulates interiorly with the other side of the pubis, joining at the pubic symphysis. Posteriorly it articulates with the sacrum, the Acetabulum proximally articulates with Femur bone. So therefore there are three articulation points for the pelvic girdle.
The femur articulates with the coxal bone at the hip joint. This joint is a ball-and-socket joint, allowing for a wide range of movement in the hip. The femur head fits into the acetabulum of the coxal bone.
Ilium Ischium Pubis The hip bone, is formed by the fusion of the ilium, the ischium, and the pubis, which occurs by the end of the teenage years.
The head of the femur articulates with the os coxa (pelvis) at the acetabulum. The acetabulum is the rounded socket that the head of the femur fits into. It also allows sliding of the pelvic bones and rotation. This joint is a synovial joint and is an example of a "ball-and-socket" joint.
The acetabulum is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint
femur
It is called acetabulum. Acetabulum articulates with round head of femur bone.
* deep socket in the coxal bone* formed where the ilium, ischium, and pubis bones fuse* the head of the femur, the thigh bone, fits in the acetabulumAcetabulum is the area on the pelvis where the head of the femur joins the pelvis. It is a concave surface that allows for the forming of the hip joint which allows you kick your leg up.The hip has these two bowl shaped regions into which the upper femur fits. This is the hip joint. That bowl shaped region is called the acetabulum.
The hip joint if formed by the head of the femur and the acetabulum, which is a "cup" or concave structure integral to the pelvis. Below you'll find links to the related Wikipedia post where you can find more information and pictures.
The hip socket is called the acetabulum; the hip bone is called the pelvis or pelvic girdle. The joint is the femoro-acetabular or femoro-pelvic joint.
The deep indentation formed by the ilium, ischium, and pubis is called the acetabulum. The acetabulum is a cup-shaped socket where the head of the femur (thigh bone) articulates to form the hip joint.
The cup-shaped depression on the hip joint that receives the head of the femur is called the acetabulum. It forms part of the hip bone structure known as the pelvis and allows for the articulation and movement of the femur within the hip joint. The acetabulum provides stability and support for the hip joint during weight-bearing activities.
