Question

1. Give the difference between the cardiac, smooth and voluntary muscles?
2. Give the difference between Isometric and Isotonic muscle contraction?​

Answer 1

Explanation:

1. Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary. ... Cardiac muscle is also an involuntary muscle but is more akin in structure to skeletal muscle, and is found only in the heart.

2. Isotonic muscle contraction produces limb movement without a change in muscle tension, whereas isometric muscle contraction produces muscle tension without a change in limb movement.
