Question: Which tissue brings about movement in animals?

ANS:

• Muscle tissue brings about movement in animals.
• This type of tissue is specialized for contraction, which allows animals to move their bodies, maintain posture, and perform various voluntary and involuntary movements.
• Muscle tissue is composed of specialized cells called muscle fibers or myocytes.
• Myocytes contain contractile proteins, such as actin and myosin, which slide past each other during contraction, generating force and shortening the muscle fibers.
• There are three main types of muscle tissue found in animals.

Skeletal Muscle:

• Skeletal muscle is attached to bones and is responsible for voluntary movements.
• It allows us to move our limbs, perform facial expressions, and engage in activities such as walking, running, and lifting objects.

Cardiac Muscle:

• Cardiac muscle is found exclusively in the heart.
• It is responsible for the rhythmic contractions that pump blood throughout the circulatory system.

Smooth Muscle:

• Smooth muscle is found in the walls of hollow organs, blood vessels, and other structures throughout the body.
• It is responsible for involuntary movements, such as the contraction of the stomach and intestines during digestion, constriction of blood vessels, and regulation of airflow in the respiratory system.
• Smooth muscle appears smooth under a microscope, hence its name.
