B
Involuntary muscles are striated, while voluntary muscles are non-striated.

Verified step by step guidance

Begin by understanding the basic types of muscle tissues: voluntary and involuntary. Voluntary muscles are primarily skeletal muscles, while involuntary muscles include smooth and cardiac muscles.
Recognize the control systems for these muscle types: Voluntary muscles are controlled by the somatic nervous system, which allows conscious control over movements. Involuntary muscles are controlled by the autonomic nervous system, which regulates unconscious functions.
Examine the structural differences: Voluntary muscles (skeletal muscles) are striated, meaning they have a banded appearance. Involuntary muscles can be either striated (cardiac muscles) or non-striated (smooth muscles).
Identify the location and function: Voluntary muscles are typically attached to bones and are responsible for movement. Involuntary muscles are found in the walls of internal organs and blood vessels, playing roles in functions like digestion and circulation.
Consider the contraction speed: Voluntary muscles generally contract quickly and with force, while involuntary muscles, particularly smooth muscles, contract more slowly and rhythmically.
