Overview of the Nervous System Practice Test

Release of adrenaline from glands by sensory neurons, which bypass the CNS and act directly on target organs.

Detection of light by retinal receptors, which occurs entirely within motor neurons leaving the spinal cord.

Production of digestive enzymes in the stomach, which is primarily controlled by voluntary somatic muscle contractions.

Transmission of signals between the brain and peripheral nerves, impairing sensation, movement, and many reflexes below injury level.
