What type of joint is a hip joint? A) a ball-and-socket joint B) a hinge joint C) an ellipsoidal joint D) a pivot joint

## Step 1 hip joint is a type of synovial joint, which is a freely movable joint. This type of joint is characterized by the presence of a joint cavity filled with synovial fluid, which allows for a wide range of motion.<br />## Step 2<br />The hip joint is a ball-and-socket joint. This type of joint allows for the greatest range of motion, including rotation. The ball-and-socket joint is characterized by a spherical head (the ball) of one bone fitting into a cup-like depression (the socket) of another bone.<br />## Step 3<br />The hip joint is a ball-and-socket joint because it allows for a wide range of motion, including rotation. This is due to the spherical head of the femur (the ball) fitting into the acetabulum of the pelvis (the socket).
