Muscle

Question 1

What is the primary function of the muscular system?

Answer 1

To facilitate movement of the body and maintain posture

The muscular system is essential for voluntary and involuntary movements.

Question 2

What are the three types of muscle tissue?

Answer 2

• Skeletal muscle
• Cardiac muscle
• Smooth muscle

Each type of muscle has distinct functions and characteristics.

Question 3

Which type of muscle is under voluntary control?

Answer 3

Skeletal muscle

Skeletal muscle is connected to bones and allows for conscious movement.

Question 4

What type of muscle is found in the heart?

Answer 4

Cardiac muscle

Cardiac muscle is involuntary and striated, unique to the heart.

Question 5

What is the role of smooth muscle?

Answer 5

To control involuntary movements within organs

Smooth muscle is found in the walls of hollow organs like the intestines and blood vessels.

Question 6

Fill in the blank: The _______ muscle type is responsible for movement of bones.

Answer 6

Skeletal

Skeletal muscles attach to bones via tendons.

Question 7

True or False: Cardiac muscle can regenerate effectively after injury.

Answer 7

False

Cardiac muscle has limited regenerative capacity compared to skeletal muscle.

Question 8

What is the function of tendons?

Answer 8

To connect muscles to bones

Tendons transmit the force generated by muscles to bones, facilitating movement.

Question 9

What is muscle hypertrophy?

Answer 9

An increase in muscle size due to exercise

Hypertrophy occurs as a response to resistance training.

Question 10

Fill in the blank: The process of muscle contraction involves _______ and myosin filaments.

Answer 10

Actin

Actin and myosin are essential proteins in the muscle contraction mechanism.

Question 11

What is the primary energy source for muscle contraction?

Answer 11

Adenosine triphosphate (ATP)

ATP provides the energy necessary for muscle fibers to contract.
