Which of these is NOT a characteristic of skeletal muscle?

Skeletal muscle is characterized as being striated in appearance and under voluntary control. This means that these muscles can be consciously controlled, allowing for precise movements associated with activities such as walking, running, and grasping objects.

Furthermore, skeletal muscles are innervated by the somatic nervous system, which is responsible for voluntary movements. This control distinguishes skeletal muscles from other types of muscle, such as cardiac muscle (which is involuntary and striated) and smooth muscle (which is also involuntary but non-striated).

Therefore, the inclusion of involuntary control as a characteristic does not apply to skeletal muscle, making it the correct identification for something that is not a characteristic of skeletal muscle. This aspect is crucial for understanding how different muscles function within the body and how they are controlled.
