1. Responsiveness (Ablility for a muscle to respond to chemical signals)

2. Conductivity (Ablility for a muscle to send a signal to the membrane)

3. Contractility (Ability of a muscle to contract / shorten and move bone)

4. Extensability (Ablility for a muscle to extend and move bone)

5. Elastisity (Ablility for a muscle to return to original position)

1. Vein / Artery / Nerve

2. Perimysium

3. Epimysium

4. Muscle fiber

5. Fascicle

6. Perimysium

7. Tendon

8. Bone

*Note: Deep Facsia is on outside of muscle from tendon and Myofibrils are part of muscle fibers

What tissue binds Muscle to Muscle

When a muscle moves a bone

What is the bone moving called (1)

and

What is the Bone that DOESN'T move called (2)

1) Insertion

2) Origin

Muscle that actually CONTRACTS and MOVES the bone

ie. Tricep is prime mover / antagonist of flexation at the elbow

QUICK!!! KNOW THE STUFF ABOUT HOW A MUSCLE CONTRACTS (AS IN THE STUFF INVOLVING ATP)

Volentary - You caused the movement (bicep curl)

Involentary - Your body does it naturally (shivering, heart beating)
