A movement is defined as a change in the position of a body. Many movements take place in our body and in other organisms to move from one place to another. The term locomotion is mainly used to describe the change of position of the whole organism. Moving our eyelids, rotating our neck, nodding our head, moving the jaw muscles are examples of different movements in the human body.
Bones and Joints
The movements in our body are mainly because of the teamwork of bones and muscles. Bones are the framework of a skeletal system, provides shape to the body protects the inner organs and helps in movement. Joints are the location where two or more bones meet.
Types of Joints
There are two main types of joints.
Immovable joints- It is also called the fixed joints. These joints do not have any kind of movements in their joint cavity. Skull bone, pelvic girdle, and the root of a tooth and the sockets are examples of fixed or immovable joints.
Moveable joints- These joints are free to move in all its directions. The different types of movable joints in our body include:
- Pivot Joints- It is the joint between the skull and the vertebral column. This type of joint allows up and down and side to side movements.
- Hinge joints- It is the knee and elbows joint. This type of joint allows only up and down movement.
- Gliding joints- It is the wrist joint and the joints between the rings of the backbone. This type of joint allows the bones to glide up and down, left and right, and diagonally.
- Ball and socket joint- It is the joints between the shoulder and the upper arm. This type of joint allows permits movement in all directions.
