Question
The muscles of the heart is made up of which kind of tissue?
- Unstriated
- Smooth
- Skeletal
- Cardiac
Hint:
The muscles of the heart have a special quality of contraction and relaxation.
The correct answer is: Cardiac
- The muscles of the heart are made up of cardiac muscles.
- The heart consists of muscles that are composed of cardiac muscle tissue. This tissue layer lies between the endocardium and epicardium. Here, the endocardium refers to the outer layer of the heart, and the epicardium is known as the inner layer of the heart.
- The cardiac muscles are of great importance to the heart. This is because they have a special property of contraction and relaxation, despite of smooth appearance. This causes the circulation of blood through the body.
The heart is the only organ that consists of cardiac muscles. No other organ possesses this musculature.
