Question

Analyze the descriptions below to identify the one that correctly differentiates between the types of muscle tissue.

a) Skeletal muscle is involuntary and found in the walls of hollow organs.
b) Cardiac muscle is striated and under voluntary control.
c) Smooth muscle is multinucleated and attached to bones.
d) Skeletal muscle is striated and under voluntary control.

Answer 1

Skeletal muscle is striated and under voluntary control, while smooth muscle is not striated and is involuntary. Cardiac muscle is also striated but is not under voluntary control.

Step-by-step explanation:

The correct description that differentiates between the types of muscle tissue is option d) Skeletal muscle is striated and under voluntary control.

Skeletal muscle tissue forms skeletal muscles, which attach to bones and control voluntary movements. It is striated, meaning it has visible stripes due to the arrangement of contractile proteins actin and myosin. It is also under voluntary control, meaning we can consciously control its movement.

Cardiac muscle tissue is found only in the heart and is responsible for pumping blood throughout the body. It is also striated but is not under voluntary control.

Smooth muscle tissue occurs in the walls of hollow organs and blood vessels. It is not striated and is involuntary, meaning we cannot consciously control its movement.
