Document Summary
The skeletal system and attacked muscles determine which movements are. The primary motor cortex initiates commands for action: non-primary cortex is an additional source of motor commands. The celebrellus, and basal ganglia modulate activities of these control systems via raw thalamus.

A muscle spindle is a capsule, buried in other muscle bers, that contains intramural bers - it responds to stretch action potentials in a erent sensory nerves. stretch. If a muscle is stretched, the muscle spindle also stretches and triggers. The signal informs the spinal cord and brain about the extent and rate of (after side) of the myotonic (stretch) re ex. When you contract a muscle, the spindle should get oppy . All animals have sensory organs containing receptor cells that sense some stimuli but not others.
