The facial muscles are like elastic sheets that are stretched in layers over the cranium, facial bones, the openings they form, and the cartilage, fat, and other tissues of the head. These are the muscles of facial expression, acting singly and in combination.
Eye Muscles
Tongue Muscles
Internal Jaw Muscles
Upper Face Muscles
Lower Face Muscles
Functions of muscles:
Allow a body part to move in response to a force (e.g. gravity) in a controlled way. The muscle lengthens, but still exerts a force (usually against gravity) • Hold a body part stationary against a force.
Types: Intrinsic (in the same region like skull), extrinsic (between two regions like spine and skull) and antagonist.(opposing the prime mover)

Is it almost time for you to go to school? Didn't we finish our homework last night?
Well - it is the function of the muscles to move the bones in our body. I did not know that there were 5 types of muscles on the face. They are Skeletal (moves bones) Smooth, (moves things like eyelids) and cardiac - your heart.

Muscles are created by All Mighty God to move things in the living beings. These are highly organized contrating proteins. They have superb sliding structures where cylinders of proteins move in each other.
There are two types of muscle: Slow contracting and fast contracting. These are supplied by different types of nerves.

The main function of muscles is for motion, for example in conjunction with bones for walking. Muscles may work alone e.g. the diaphragm for breathing, and the heart for circulating blood.
Types of muscles
Different types of muscle respond, contract, and relax at different rates.
Skeletal muscles are striated (have distinct bands) made up of fibres (long cells). The cells are multinucleated (many cell nuclei) and contract and relax quickly. These are voluntary muscles attached to the skeleton that help to move the bones. There are nearly 700 skeletal muscles spread all over the body.
Visceral muscles are smooth and without banding. They have short fibres and single cell nuclei. These are involuntary muscles e.g. found in walls of blood vessels and viscera (organs in the abdominal cavity).
Cardiac muscles are striated (but less distinct than skeletal muscles), and are involuntary .

Too actually move limbs ! The brain is not a muscle but it becomes more effective with use...
