Difference Between Cardiac Muscle And Skeletal Muscle

The human body is composed of three types of muscles viz cardiac muscles, smooth muscles, and skeletal 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 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. 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. The important differences between cardiac muscles and skeletal muscles have been discussed below.

Difference Between Cardiac Muscle And Skeletal Muscle

Properties Cardiac Muscle Skeletal Muscle
Found In heart only Attached to bones of the entire body
Length Shorter Longer
Controlled by Autonomic nervous system Somatic nervous system
Shape Semi-spindle Cylindrical
Function Movement of the body Pumping blood away from the heart
Gap junctions Present Absent
Cell type Uninucleated Multinucleated
Endomysium Dense Less Dense
Speed of contraction Less Fast
Contracts Without neural stimulation With neural stimulation
