A neuron found in the center of the spinal cord that receives information from the sensory neurons and sends commands to the muscles through motor neurons. Interneurons also make up the bulk of the neurons in the brain
Cerebellum
Part of the lower brain located behind the pons that controls and coordinates involuntary, rapid, fine motor movement
Cerebral Hemispheres
The two sections of the cortex on the left and right sides of the brain
Autonomic Nervous System
Division of the PNS consisting of nerves that control all of the involuntary muscles, organs, and glands
Agonists
Chemical substances that mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell, increasing or decreasing the activity of that cell
Association Areas
Areas within each lobe of the cortex responsible for the coordination and interpretation of information, as well as higher mental processing
Axon
Long tube-like structure that carries the neural message to other cells
Endocrine Glands
Glands that secrete chemicals called hormones directly into the bloodstream
Inhibitory Neurotransmitter
Neurotransmitter that causes the receiving cell to stop firing
Occipital Lobes
Sections of the brain located at the rear and bottom of each cerebral hemisphere, containing the visual centers of the brain
