Difference Between Cardiac Muscle And Skeletal Muscle

The human body is comprised of three types of muscles :

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.

Smooth muscles.

Smooth muscles are found on the cell walls of internal organs which is self-stimulating, has a low speed of contraction and energy requirement, and is responsible for performing involuntary muscular 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.

 The important differences between cardiac muscles and skeletal muscles have been discussed below.
