Difference Between Cardiac and Skeletal Muscle 

Location 
Cardiac: Found only in the heart. 
Skeletal: Attached to bones. 

Control 
Cardiac: Involuntary (autonomic). 
Skeletal: Voluntary (somatic). 

Cell Structure 
Cardiac: Branched cells, usually one nucleus, intercalated discs. 
Skeletal: Long cylindrical fibers, multinucleated, no intercalated discs. 

Striations 
Both are striated. 

Function 
Cardiac: Pumps blood continuously. 
Skeletal: Movement, posture, heat production. 

Contraction Characteristics 
Cardiac: Rhythmic, automatic, does not fatigue, slower contractions. 
Skeletal: Fast contractions, can fatigue, requires neural stimulation. 

Regeneration Ability 
Cardiac: Very limited regeneration. 
Skeletal: Moderate regeneration via satellite cells. 
 
 
 
In summary: 
Cardiac muscle is found only in the heart, works involuntarily, has branched single-nucleus cells with intercalated discs, contracts rhythmically without fatigue, and has very limited ability to regenerate. 
Skeletal muscle attaches to bones, works voluntarily, has long multinucleated fibres without intercalated discs, contracts quickly but can fatigue, and has moderate regeneration ability through satellite cells.
