26
Q

Defeniton for antagonistic piars,antagonistic and agonist

A

To solve this problem, some muscles are arranged in twos, called an antagonistic pair. When one muscle contracts (agonist) the other relaxes (antagonist) to allow the joint to work.

27
Q

Voluntary and involuntary muscke defenition

A

Voluntary muscles are under our conscious control so we can move these muscles when we want to. These are the muscles we use to make all the movements needed in physical activity and sport.

Involuntary muscles are not under our conscious control which means we can’t make them contract when we think about it.

28
Q

Cardiac muscles and smooth muscles and skeletal muscle

A

smooth muscle – found in the internal organs and blood vessels - this is involuntary
cardiac muscle – found only in the heart - this is involuntary
skeletal muscle – attached to the skeleton - this is voluntary
