Muscular System Functions and Structures

The video tutorial discusses the muscular system, highlighting the importance of muscles for movement and survival. It explains the difference between voluntary and involuntary muscles, focusing on cardiac, smooth, and skeletal muscles. The tutorial also covers muscle health, common injuries, and the role of tendons in connecting muscles to bones.

Why is the muscular system crucial for our survival?

• It helps us digest food.

• It regulates body temperature.

• It provides energy to the body.

• It allows us to move and perform vital functions.

Which part of the brain controls voluntary muscles?

• Cerebellum

• Cerebrum

• Medulla

• Brain stem

What is the primary function of cardiac muscle?

• To regulate breathing.

• To support skeletal movement.

• To pump blood throughout the body.

• To aid in digestion.

Which type of muscle is responsible for the movement of internal organs?

• Smooth muscle

• Cardiac muscle

• Voluntary muscle

• Skeletal muscle

What is the function of smooth muscle in the stomach?

• To regulate temperature.

• To support the skeleton.

• To crush and move food.

• To pump blood.

What distinguishes skeletal muscle from other types of muscles?

• It is involuntary.

• It is found in the heart.

• It is smooth in texture.

• It is responsible for voluntary movements.

Approximately how many muscles are there in the human body?

• 900

• 1200

• 300

• 600

What is the role of tendons in the muscular system?

• They store energy for muscles.

• They protect muscles from injury.

• They help muscles contract.

• They connect muscles to bones.

How can you maintain healthy muscles?

• By avoiding exercise.

• By eating junk food.

• By regular exercise and a balanced diet.

• By sleeping all day.

What happens when a tendon becomes inflamed?

• It improves blood circulation.

• It increases flexibility.

• It causes tendonitis, leading to pain.

• It strengthens the muscle.
