Answer 2

Answer:

Three features of Cardiac muscles:

1)Cardiac muscles are involuntary muscles. They are involved in continuous rhythmic contraction and relaxation.

2)Cardiomyocytes or the cardiac cells are uninucleate, cylindrical, and elongated.

3)Cardiac muscles display faint cross-striations which do not get fatigued under normal circumstances.

Difference between them:

Cardiac muscles.

Cardiac muscles are found in the heart which is self-stimulating, has an intermediate speed of contraction and energy requirement, and is responsible for performing muscular involuntary movements.

Skeletal muscles.

Skeletal muscles are attached to bones all over the body which does not self-stimulate, has a high speed of contraction and energy requirement, and is responsible for performing voluntary muscular movements.
