VOLUNTARY MUSCLES Meaning and
Definition
-
Voluntary muscles, also known as skeletal muscles or striated muscles, are a type of muscle tissue mainly attached to bones, responsible for controlled movements of the body. These muscles are under conscious control and require nerve impulses from the brain and spinal cord to initiate and regulate their contractions.
The term "voluntary" implies that individuals have the ability to control these muscles consciously, deciding when to contract or relax them to perform specific movements. This control allows individuals to engage in activities such as walking, writing, talking, and countless other voluntary actions.
Voluntary muscles are characterized by their striated appearance, visible when observed under a microscope. This appearance is due to the organization of contractile proteins within the muscle fibers. These proteins, actin and myosin, slide past each other during muscle contraction, resulting in the shortening of the muscle and the generation of force.
Voluntary muscles can vary in size and shape throughout the body, from tiny muscles that control the intricate movements of the fingers to large muscles that power movements such as running or jumping. They also exhibit remarkable adaptability, being able to grow and strengthen with regular exercise and physical training.
Overall, voluntary muscles enable individuals to perform a wide range of movements and activities, allowing for mobility, physical performance, and the ability to interact with the environment through deliberate and controlled movement.

Etymology of VOLUNTARY MUSCLES
The word "voluntary" originates from the Latin word "voluntarius", which means "of one's free will" or "willingly". It comes from the root "voluntas", meaning "will" or "wish". In the context of muscles, "voluntary" refers to the muscles that are under conscious control, allowing individuals to move them at will.
The term "muscle" has its roots in the Latin word "musculus", meaning "little mouse". It is derived from the resemblance of some muscles, particularly the biceps, to small rodents when they contract.
Therefore, "voluntary muscles" refers to the muscles that a person can control consciously, moving them as desired. These muscles are distinct from "involuntary muscles" or "smooth muscles", which function automatically and are not under conscious control.
