The muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates.
Whole muscles exhibit characteristics that are more complex than those of individual muscle fibers or motor units. Instead of responding in an all-or-none fashion, whole muscles respond to stimuli in a graded fashion, which means that the strength of the contractions can range from weak to strong.
Somatic Division
The Somatic Division
Skeletal muscles control voluntary movements.
The somatic nevous system controls voluntary movements while the autonomic nervous system only controls involuntary movements.
It controls your voluntary movements. It allows you to imporve your driving by experience.
The primary motor cortex controls voluntary movements. Damage to the primary cortex would impact the ability to control voluntary movement.
The part of the brain known as the motor cortex controls all voluntary movements, including running.
The Motor Area registers information and controls movement of the body.
The cerebellum is the motor movements center of the brain, governing posture, coordination, balance, speech, etc.
The pons, the medulla, and the cerebellum are the three parts of the hindbrain. The hindbrain controls most voluntary and involuntary movements.
The frontal lobe controls motor functions and permits voluntary muscle control. The brain stem
The somatic nervous system controls the skeletal system and voluntary movement by stimulating muscle contraction. Parts of the somatic nervous system are spinal nerves, cranial nerves, association nerves.
