Match the following

• assists the agonists

• Synergist

Skeletal muscles are

• attached to muscles via ligaments

• Voluntary

• Involuntary

• attached to bones via tendons

Nervous Control is where

• nerve stimuli control muscle action

• can increase in size (growth) with an increase in activity muscle

• muscles can return to their original size and shape once stretched

• muscles can decrease in size (waste) as a result of injury, illness or lack of exercise.

In the "reciprocal inhibition" relationship the muscle causing the movement is known as ​ (a)  

• the Agonist
• Antagonist
• Synergist
• Stabiliser
