Answer 2

Answer:

The statement not related to the cardiac muscles is c) They are non-striated, multinucleated, and branched muscles.

Explanation:

• Only the heart contains the striated muscle known as cardiac muscle.

• Cardiac muscle fibers are branching, contain a single nucleus, and are connected by intercalated discs.

• Cells in cardiac muscle tissue, or the myocardium, respond to electrical impulses from the nervous system by contracting and expanding.

• The cardiac muscle must contract and relax quickly and without conscious effort in order to circulate blood throughout the circulatory system.

• The heart's walls are home to cardiac muscle cells, which are striated and controlled by an involuntary process.
