Which type of muscle is classified as under voluntary nervous control?

Skeletal muscle is classified as under voluntary nervous control because it is the type of muscle that is consciously controlled by the nervous system. This means that individuals can decide when to contract these muscles, such as when walking, reaching, or performing any physical activity that requires movement. Skeletal muscles are attached to bones by tendons and are responsible for the movement of the skeleton, enabling a wide range of bodily motions.

In contrast, cardiac muscle, which makes up the heart, operates involuntarily and is regulated by the autonomic nervous system, meaning we cannot consciously control its contractions. Similarly, smooth muscle, found in various organs (like the intestines and blood vessels), is also involuntary and responds automatically to various physiological needs without direct control by the conscious mind. The term "involuntary muscle" typically refers to muscles that are not under conscious control, which includes both cardiac and smooth muscles. Thus, skeletal muscle stands out as the muscle type that is indeed under voluntary control.
