Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is a Cardiac Muscle cell made?
A
A cardiac muscle is made by a dead piece of skin
B
Cardiac muscle fibers also possess many mitochondria and myoglobin, as he cell is produced primarily through aerobic metabolism. Cardiac muscle fibers cells also are extensively branched and are connected to one another at their ends by intercalated discs.
C
There were white out conditions in the town; subsequently, the roads were impassable
D
The quick brown fox jumps over the lazy dog.
Explanation: 

Detailed explanation-1: -It is composed of individual cardiac muscle cells joined by intercalated discs, and encased by collagen fibers and other substances that form the extracellular matrix. Cardiac muscle contracts in a similar manner to skeletal muscle, although with some important differences.

Detailed explanation-2: -Cardiac muscle tissue, or myocardium, contains cells that expand and contract in response to electrical impulses from the nervous system. These cardiac cells work together to produce the rhythmic, wave-like contractions that is the heartbeat.

Detailed explanation-3: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-4: -The individual cardiac muscle cell (cardiomyocyte) is a tubular structure composed of chains of myofibrils, which are rod-like units within the cell. The myofibrils consist of repeating sections of sarcomeres, which are the fundamental contractile units of the muscle cells.
