How do you distinguish between a skeletal muscle and a cardiac muscle?
Skeletal Muscle |
Cardiac Muscle |
The cells of skeletal muscles are unbranched. |
The cells of cardiac muscles are branched. |
Intercalated disks are absent. |
The cells are joined with one another by intercalated disks that help in coordination or synchronization of the heart beat. |
Alternate light and dark bands are present. |
Faint bands are present. |
They are voluntary in nature. |
They are involuntary in nature. |
They contract rapidly and get fatigued in a short span of time. |
They contract rapidly but do not get fatigued easily. |
They are present in body parts such as the legs, tongue, hands, etc. |
These muscles are present in the heart and control the contraction and relaxation of the heart. |
Lack of relaxation between successive stimuli in sustained muscle contraction is known as
fatigue
