Muscles in the Heart
Introduction:
The heart is a vital organ in our body that pumps blood throughout the circulatory system. Like other muscles in our body, the heart also contains muscle tissues that allow it to contract and relax, enabling it to pump blood effectively.
Types of Muscles:
There are three main types of muscles in our body: skeletal, smooth, and cardiac muscles.
Skeletal Muscles:
Skeletal muscles are the muscles that are attached to our bones and help us move our body parts according to our will. These muscles are under voluntary control, meaning we can consciously control their movement. For example, when we want to move our limbs, fingers, or neck, we can do so by the contraction and relaxation of skeletal muscles.
Smooth Muscles:
Smooth muscles are found in various organs of our body, such as the digestive system, respiratory system, and blood vessels. These muscles are not under our conscious control and are involuntary. They are responsible for the movements of internal organs, like the contraction and relaxation of the digestive tract or the dilation and constriction of blood vessels.
Cardiac Muscles:
Cardiac muscles are unique to the heart and are responsible for its contractions. These muscles are involuntary, meaning we cannot consciously control their movements. The contraction and relaxation of cardiac muscles are regulated by specialized cells within the heart called pacemaker cells.
Explanation:
The correct answer to the question is option 'B' - Cardiac muscles. The muscles found in the heart are known as cardiac muscles. These muscles have a unique structure and function that enables the heart to contract rhythmically and pump blood throughout the body. Unlike skeletal muscles, cardiac muscles are involuntary and are not under our conscious control.
Summary:
In summary, the muscles found in the heart are known as cardiac muscles. These muscles are involuntary and are responsible for the rhythmic contractions of the heart, allowing it to pump blood throughout the body. Unlike skeletal muscles, which are under our conscious control, cardiac muscles cannot be controlled by our will.
