Question

B) Involuntary muscles are attached to bones; voluntary muscles are not.
C) Voluntary muscles are only found in the arms and legs; involuntary muscles are found in internal organs.
D) Involuntary muscles can be consciously controlled; voluntary muscles cannot.

Answer 1

Voluntary muscles, such as skeletal muscles, can be controlled consciously. Involuntary muscles, like cardiac and smooth muscles, cannot be consciously controlled and work automatically.

Step-by-step explanation:

Muscles that are under an individual's conscious control are called voluntary muscles. Examples of voluntary muscles include skeletal muscles which are responsible for movements like walking and lifting objects. On the other hand, involuntary muscles cannot be consciously controlled and work automatically without us thinking about them. Examples of involuntary muscles include cardiac muscles found in the heart and smooth muscles found in the digestive system.
