Verified step by step guidance
1
Identify the two types of muscle tissues mentioned: voluntary and involuntary muscles.
Understand that voluntary muscles are those that can be controlled consciously. These are primarily the skeletal muscles, which are responsible for movements like walking, lifting, and other activities that require conscious effort.
Recognize that involuntary muscles are those that operate without conscious control. These include smooth muscles found in the walls of internal organs and cardiac muscles found in the heart.
Clarify that the primary difference lies in the control mechanism: voluntary muscles are under conscious control, while involuntary muscles function automatically without conscious input.
Review the options provided and match them with the correct explanation: Voluntary muscles are controlled consciously, while involuntary muscles are controlled unconsciously.
