ANSWER
Q-1). Show the difference between the three types of muscle fibres with diagrams.
Ans. The following difference between striated muscles, smooth muscles and cardiac muscles are:
1). Striated Muscles:-
=> Cells are cylindrical.
=> Cells are unbranched.
=> These are voluntary muscles.
=> They contract rapidly and soon undergo fatigue.
=> These muscles are present in our body parts such as the hands, legs, tongue, etc.
2). Smooth Muscles:-
=> Cells are cylindrical.
=> Cells are unbranched.
=> These are involuntary muscles.
=> They contract slowly and do not undergo fatigue.
=> These muscles control the movement of food in the alimentary canal, the contraction, and relaxation of blood vessels, etc.
3). Cardiac Muscles:-
=> Cells are cylindrical.
=> Cells are branched.
=> These are involuntary muscles.
=> They contract rapidly but do not undergo fatigue.
=> These muscles control the contraction and relaxation of the heart.
Answer:
The three types of muscle fibres are striated muscles, smooth muscles (unstriated muscle fibre), and cardiac muscles.
