16. Differentiate three types of muscular tissues, based on structure, location and function, with diagram
Answers
Answer:
The three types of muscles tissue are cardiac, skeletal and smooth muscles. Some of these muscles have voluntary movement, which means that you think and tell them how to move. Other muscles have involuntary movement, which means that your brain automatically tells them how to move and complete the important functions in your body that keep you alive.
1.Cardiac muscles:- When you run really fast, you probably notice that your heartbeat speeds up without you telling it to. Your heart also continues to beat even when you are asleep. This is because your heart is made of involuntary cardiac muscles that keep it pumping all of the time without you telling it to. This is how you stay alive.
2. Involuntary muscles(smooth muscles):- Another type of muscle is your smooth muscle. Smooth muscles also move involuntarily and work without you having to think about them. Smooth muscles are found inside of your organs, including your stomach, liver, kidneys and lungs. These muscles ensure that each organ is able to perform its important bodily function, such as digesting food, removing germs from your blood and breathing.
3.Voluntary muscles(skeletal muscles):- You may hold your arms up after exercising to check the size of your muscles. Arm muscles are part of your skeletal muscles, which are connected to most of your skeleton. They are voluntary, which means that you think about and tell these muscles how to move.
For example, when you are ready to get out of bed in the morning, you tell your leg muscles to stretch and move towards the floor. Skeletal muscles are also found in your face. You tell the skeletal muscles of your face to smile, frown and talk. Your skeletal muscles allow your body to complete all of the movements that you use daily.

Types of Muscular Tissue
The muscular tissue is of three types:
Skeletal Muscle Tissue
Smooth Muscle Tissue
Cardiac Muscle Tissue
skeletan muscle tissue
These muscles are attached to the skeleton and help in its movement.
These muscles are also known as striated muscles because of the presence of alternate patterns of light and dark bands.
These light and dark bands are sarcomeres which are highly organized structures of actin, myosin, and proteins. These add to the contractility and extensibility of the muscles.
Skeletal muscles are voluntary muscles composed of muscle fibers.
40% of our body mass comprises skeletal muscles.
Each skeletal tissue contains myofibrils.
The cells of these tissues are multinucleated.
These are provided with blood vessels and many elongated mitochondria and glycogen granules.
They bring about the movement of the organs of th
smooth muscle tissue
These are non-striated, involuntary muscles controlled by the Autonomous Nervous System.
It stimulates the contractility of the digestive, urinary, reproductive systems, blood vessels, and airways.
The actin and myosin filaments are very thin and arranged randomly, hence no striations.
The cells are spindle-shaped with a single nucleus.
cardic muscl tissue
These are found only in the heart.
These are involuntary muscles and the heart pumps the blood through cardiac contractions.
The cells of the cardiac muscles known as the cardiomyocytes are striated.
They are single-celled and uninucleated.
The ends of the cells are joined and the junctions are called intercalated discs. The cells are attached to each other by desmosomes.
