Question

select the statement that accurately describes the muscular system.
a. the muscular system is composed of two different types of muscles.
b. the muscular system is composed of muscles, tendons, and ligaments.
c. the muscular system is responsible for controlling the actions of smooth and cardiac muscles.
d. the muscular system is composed of smooth, skeletal, and cardiac muscles.

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

• Option A: The muscular system has three types (smooth, skeletal, cardiac), not two. Eliminate A.
• Option B: Ligaments are part of the skeletal system (connect bones), and tendons connect muscles to bones. The muscular system is mainly muscles. Eliminate B.
• Option C: Smooth and cardiac muscles are involuntary (controlled by autonomic nervous system), while skeletal is voluntary. The muscular system doesn't "control" smooth/cardiac in the way stated. Eliminate C.
• Option D: The muscular system is made of smooth (e.g., in organs), skeletal (for movement), and cardiac (heart) muscles. This is correct.

Answer:

D. The muscular system is composed of smooth, skeletal, and cardiac muscles.
