Question

what are the difference between straited unstraiten and cardic muscles

Answer 1

Skeletal muscles are striated and are the muscles that are in voluntary control. These include biceps(arm), pectoralis major(chest) and other muscles that you can move. These muscles are striated and has many nuclei. 

Smooth muscles are not striated and are the muscles that are not in voluntary control. These include organs and blood vessels, excluding heart. These muscles are unstriated with one nucleus. Smooth muscles has only one nucleus. 

There is only one place where cardiac muscle is found: the heart. Also called myocardium, this muscle is striated and has one nucleus. Cardiac muscle also contains intercalated disc, which acts as a junction between the two muscle cells.

Answer 2

Striated muscles- striations are present, voluntary mean in our control, it gets fatigue

Unstriated muscles - striations are not present, also known as smooth muscle, involuntary mean not in our control, less fatigue

Cardiac - in these striations are present, eg heart, not fatigued
