Example of striated muscle is Correct Answer Cardiac muscle
Concept-
- Striated muscles are muscles with striations and they are also referred to as skeletal muscles.
- Non striated muscles are muscles without striations, which are known as smooth muscles. Cardiac muscles are a specialized type striated muscle lining the heart.
- Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle.
Key Points
- It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
- The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation.
- Four characteristics define cardiac muscle tissue cells: they are involuntary and intrinsically controlled, striated, branched, and single nucleated.
- They are involved in continuous rhythmic contraction and relaxation.
- Cardiomyocytes(cardiac cells) have the potential to carry out the contractile function of the heart thus enabling the pumping of blood throughout the body.
- Cardiac muscles are found in the heart which is self-stimulating, has an intermediate speed of contraction and energy requirement, and is responsible for performing muscular involuntary movements.
- Additional Information
- The walls of the alimentary canal include layers of smooth muscle controlled by the autonomic nervous system. Alternating contraction and relaxation of these muscles is called peristalsis.
- Reproductive tract muscles are smooth muscles.
