Your femur.
there is no connection between the size of your head and your femur bone
Medial Femoral Circumflex... Without this artery blood supply to the head of the femur is cut off and the head of the femur will die
The bone marking of the femur that articulates with the pelvic girdle is called the head of the femur.
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.
It is called acetabulum. Acetabulum articulates with round head of femur bone.
The annular ligaments are circular fibers that wrap around the joint capsule of the neck of the femur to help hold the head of the femur in the acetabulum.
It is true that the head of the femur in humans forms approximately 2/3 of a sphere - the remainder of the surface is the neck of the femur, a relatively narrow column of bone that connects the head to the diaphysis of the bone.
head of the femur
Your femur, or thighbone, is the largest bone in your body. We have 2 femur, 1 each leg. The head of your femur fits into your hip socket and the bottom end connects to your knee.
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 fovea capitis is located on the head of the femur bone, specifically on the medial and slightly posterior aspect. It is a small depression that serves as the point of attachment for the ligamentum teres.
