Human Body And Its Movements
The human skeleton is the internal framework which is responsible for giving support, shape and protection to our bodies. It contains 206 bones, each playing a distinct yet important task. The skeleton can be classified into two parts called as the axial and the appendicular. The axial skeleton comprises of the central part of the skull, spine, and ribs and the appendicular skeleton consists of the arms and legs.
Terms -
Limbs: The arms or legs of an animal.
Bones: These are the hard white structures below our skin that protect our internal organs. Bones are incapable of bending.
Joints: These are defined as the points at which two bones are fitted together. These are the points at which we can rotate and bend our bodies.
Types of Joints and their Location in Human Body
A Pivot joint is a joint that rotates.. Examples of pivot joints in the body in the neck that allows the head to rotate and the ones between the radius and ulna that allow forearm rotation.
When bones can move along one axis, it indicates the presence of Hinge joint. e.g. Elbows and Knees.
In the Ball and Socket joint, a partial spherical structure is present inside a socket allowing movement in all directions. e.g. hips and arms
As the name suggests Fixed joint allows no movement to occur. e.g Skull
