Exploring the Muscular System

What are the three types of muscles in the human body?

• Cardiac, striated, and voluntary muscles

• Skeletal, elastic, and smooth muscles

• Skeletal, cardiac, and connective tissues

• Skeletal, smooth, and cardiac muscles

Which type of muscle is responsible for voluntary movements?

• Skeletal muscle

• Connective tissue

• Cardiac muscle

• Smooth muscle

What type of muscle is found in the heart?

• Skeletal muscle

• Smooth muscle

• Striated muscle

• Cardiac muscle

What is the main function of skeletal muscles?

• To protect internal organs from injury.

• To provide structural support to the body.

• To store calcium and other minerals.

• The main function of skeletal muscles is to facilitate voluntary movement of the body.

Which type of muscle is involuntary and found in organs?

• cardiac muscle

• striated muscle

• smooth muscle

• skeletal muscle

What is the role of smooth muscles in the body?

• Smooth muscles control involuntary movements in organs such as the intestines, blood vessels, and airways.

• Smooth muscles are involved in the production of red blood cells.

• Smooth muscles are responsible for voluntary movements in the limbs.

• Smooth muscles primarily function in the heart to pump blood.

How do muscles help in movement?

• Muscles assist in movement by generating heat and relaxing joints.

• Muscles enable movement by storing energy and releasing it slowly.

• Muscles help in movement by expanding and pushing against bones.

• Muscles help in movement by contracting and pulling on bones.

What is the function of cardiac muscle?

• To pump blood throughout the body.

• To absorb nutrients from food.

• To provide structural support to the heart.

• To facilitate gas exchange in the lungs.

What is the importance of warm-up exercises for muscles?

• Warm-up exercises are unnecessary for casual workouts.

• Warm-up exercises are important for preventing injuries and improving performance.

• Warm-up exercises can lead to muscle fatigue.

• Warm-up exercises are only for professional athletes.

How do muscles help maintain posture?

• Muscles help maintain posture by contracting to stabilize the body and support the skeletal structure.

• Muscles help maintain posture by relaxing the body and allowing it to slouch.

• Muscles help maintain posture by absorbing shock and preventing movement.

• Muscles help maintain posture by generating heat to keep the body warm.
