2. Three types of muscles. Cardiac
This muscle is only found in the walls of the heart.
They contract and relax the heart continuously to pump blood through it, without conscious effort from you.

3. Involuntary Muscles - smooth
These are the muscles around organs such as the intestines and blood vessels. Like the cardiac muscles, they work without conscious effort from you.

4. Voluntary Muscles - skeletal
These muscles are attached to the skeleton and are under your control.

5. Different types of joints

6. Antagonist & Agonist
Muscles can only pull. To make a joint move in two directions, you need two muscles that can pull in opposite directions.
Antagonistic muscles are pairs of muscles that work against each other.
One muscle contracts (agonist, or prime mover) while the other one relaxes (antagonist) and vice versa.

8. Origin & Insertion
Muscles are attached to two different bones by tendons. When the muscle contracts only one bone moves.
The place where the muscle is attached to the stationary bone is called the Origin.
The place where the muscle is attached to the moving bone is called the Insertion.

10. Synergists
Any other muscle which helps the prime mover to cause a movement is a Synergist.
An example of this is when bending the arm at the elbow, the synergist would be the brachialis muscle in the forearm.
