Answer 1. Ball and socket joints are the most movable joints of the body. This is type of synovial joints in which ball like structure of one bone fits in to the socket like depression of the another bone. Hip joints and shoulder joints are the examples of the ball and socket joints. It allows the movement in most of the directions. Other options given in the question are less movable than the ball and socket joints.
Answer 2. When two bones grow together across a joint to form single bone, it is called as synostosis. For example abnormal fusion of two cranial bones is called as craniosynostosis. Symphysis is the fibrocartilagenous fusion of two bones. Gomphosis is the the joint between teeth and maxilla.
Answer 3.Bowing of the head is the examples of flexion. Bowing is the movement between head and spinal cord that decreases the angle between the two. Hyperextension increases the angle between head and spinal cord.
Answer 4. Answer will be option e that is joint between atlas and occipital bones. Pivot joints are that Joints which allows the movement around one axis and is of rotational type. It is also called as rotary joint. Examples of pivot joints include atlas axis movements, radio ulnar joints etc.
