Answer 1

Hint: A joint is the junction of two bones that is required for movement of any kind. There are many joints in the body that may connect bone-bone or bone-cartilage. Joints are required even for the locomotor functions and are moved by the force that is generated from the muscles.

Complete solution:
There are many types of joints in our body for free movements. They are:
Ball and socket joint : As the name suggests, the joint is shaped such that one bone appears to be like ball groove and other that fits into the socket
Example: Hip joint
Hinge joint : Convex surface – concave surface arrangement
Example: Elbow joint
Gliding Joint: Like a glide
Example: Inter tarsal joints
Condyloid Joint: atlas- condyloid joint
Pivot joint: Cylindrical bone that rotates in a ring
Example : Head-neck
Hence, The joint that connects the head and neck is called pivot joint or pivotal joint and helps our head to move freely forward, backward and sideways.
Bones are part of the skeletal system in our body which forms the framework of cartilages and bones together.

Note:
Bones are made up of calcium and are required for free movement. With age, the density of the bones decreases causing joint pains in the elderly. Calcium is required for the proper functioning of bones and to keep joints healthy. Regular exercise is also helpful. Arthritis occurs if bone density is low.
