Unconscious proprioception

45

What does the corticospinal tract do?

46

What is the monosynaptic stretch reflex?

When the muscle is stretched the body reacts by firing the muscles to protect itself. It also deals with removing your hand from a hot surface.

47

What does the diencephalon do?

Coordinates how things move back and forth from conscious to unconscious thought.

48

What does the thalamus do?
