What is the Skeletal System?

The Skeletal System is the bodily system that consists of the bones, their associated cartilages, and the joints.

Functions of the Skeletal System

Gives the body its shape 

It supports the structure of the body

allows movement

Makes blood cells 

protects the organs

Stores Minerals

Different Types of joints in the Skeletal System 

The human body has three main types of joints. They’re categorized by the movement they allow, They are :

Synarthroses (immovable). These are fixed or fibrous joints. They’re defined as two or more bones in close contact that have no movement.

Amphiarthroses (slightly movable). Also known as cartilaginous joints, these joints are defined as two or more bones held so tightly together that only limited movement can take place.

Diarthroses (freely movable). Also known as synovial joints, these joints have fluid that allow all parts of the joint to smoothly move against each other.
