What is a hinge joint?
The collection of peripheral nerves that carry motor impulses from the spinal cord to muscles and sensory information from the muscles and sensory nerves to the spinal cord.
What is the peripheral nervous system?
"Built in" connections between sensory nerves, the spinal cord, and motor nerves that automatically cause movement when provoked by the appropriate stimulus.
What are reflexes?
