Structure of Joints

Section One: Main PointsSection One: Main Points

1. The skeleton helps by supporting body, protecting organs, helping with movement, storing mineral reserves, and is also a place for blood cell formation.

2. Bones are solid environments for cells and protein fibers, they are surrounded by calcium salts deposit.

3. Joints are classified as: movable, slightly movable, immovable, and freely movable.

 

Section Two: The Muscular SystemSection Two: The Muscular System

Types of Muscle Tissue

A.Skeletal Muscles

B.Smooth Muscles

C.Cardiac Muscle Muscle Contraction Control of Muscle Contraction How muscles and Bones Interact

Section Two: Main PointsSection Two: Main Points

1. The three types of muscle tissue are:cardiac, smooth, and skeletal.

2. When a thin filament, in the muscle fiber, slides over the thick filament, the muscle contracts.

3. ATP supplies the energy for muscles to contract.

Section Three: Main Points

1. The integumentary system is a barrier protecting against injury and infection. It regulates the body temperature, takes waste from the body, and protects against ultraviolet radiation from the sun.
