Anatomy and physiology
Lesson two
Calcium is needed for strong bone growth.
The skeleton is the central structure of the body, providing a framework for all soft tissues to attach to.
Long Femur, humerous
Short carpals, tarsal's
Flat cranium, ribs
Irregular ­ vertebrae
Types of joints
Fixed joints
These are also known as fibrous joints and as the name implies allow no movement across the joint.
Slightly moveable
These are also known as cartilaginous joints. They allow a small amount of movement.
Synovial joints
There are 70 synovial joints in the human body. Synovial joints are freely moveable. They include:

Types of synovial joints
Gliding
Flat surfaces can glide over each other providing a little movement in all directions. Examples include
the carpals.
Hinge
The joint can swing open until it is straight e.g. elbow and knee joint
Pivot
A ring on one bone fits over the peg of another, allowing controlled rotational movement e.g. atlas and
axis.
Condyloid
A bump on one bone sits in the hollow formed by another.
Saddle
The ends are shaped like saddles and fit neatly together e.g.…read more

The skeleton acts as a mineral reservoir for the important minerals such as calcium and phosphorus,
essential for bone growth and maintenance of bone health.
Types of Movement
Adduction adding to the body
Abduction ­ taking away from the body
Flexion ­ decreasing the angle at a joint
Rotation turning about the vertical axis of your body e.g.…read more
