Answer 1

The correct option is A Parietal bone and the temporal bone of the skull are joined by fibrous joint

Parietal bone and the temporal bone of the skull are joined by fibrous joint. The parietal bones form the posterior roof of the skull. The temporal bone is located at the lower sides of the skull and directly underneath the temple.

The first vertebra is an atlas, which articulates with the occipital condyles. Axis is the second vertebrae.

The 11th and 12th pair of ribs are called the floating ribs. It protects the kidney.

Glenoid cavity is a depression to which the femur bone articulates. It is located between the elbow joint and the shoulder.
