Which of the following statements about cardiac muscle are false:
a. Cardiac muscle depends on neural input to initiate the cardiac cycle.
b. Cardiac muscle has shorter T-tubules than skeletal muscle.
c. The intercalated discs allow for the transfer of ions between cells.
d. All of the listed statements are true.
e. Cardiac muscle has a very high amount of myoglobin.
f. Cardiac muscle is highly dependent on aerobic metabolism.

1. Cardiac muscle depends on neural input to initiate the cardiac cycle.

Explanation:

The cardiac muscle cell forms the heart of the organism and since they are muscle cells, therefore, they perform important functions. The cardiac muscle cell is responsible for the pumping of the blood in the body.

The signal for contraction and relaxation of the heart does not come from the central nervous system but in a normal body, they are auto-generated.  They receive their signals from the autonomic nerves which send when sends the signal without coordinating with the brain and the spinal cord.

Therefore they do not depend on the neural input from the brain but the signals are auto-generated.

Thus, Option-1 is correct.
