Voluntary-muscle definition

Conversely, the voluntary muscle groups in the body are paralyzed.

Normal voluntary muscle contraction begins when electrical signals are sent from the brain through the spinal cord along nerve cells called motor neurons.

Toxic doses of propantheline bromide may produce non-depolarising neuromuscular blocking effects with paralysis of voluntary muscle.

Another problem to watch for is a condition called ataxia; this is the inability to properly coordinate voluntary muscle movements.
