Answer 2

Cardiac muscles :

cardiac muscles are found in the Wall of heart only.

They are striated and involuntary.

The cardiac muscle fibres are branched and form an interconnecting network.

The fibres are uninucleate and nucleus is centrally located.

Cardiac muscles are self excitatory.

They forms a network.
