| l The neuron is the basic unit of structure and function in the nervous system | Neurons |
| muscles or glands in which neurons | Effectors |
| Contains the nucleus of the neuron | cyton |
| transmits the impulse away from the cyton | Axon |
| l The ends of axons that secrete neurotransmitters | Terminal Branches |
| l Chemicals secreted by the terminal branches that aid in the transmission of an impulse across the synapse | Neurotransmitters |
| receives the stimulus and initiates an impulse | Receptor |
| carry impulses from the receptors toward the spinal cord and brain | Sensory neuron |
| relay impulses from one neuron to another | Interneuron |
| carry impulses from brain and spinal cord toward the effectors | Motor neuron |
| l Fibers that detect stimuli and generate an impulse toward the cyton | Dendrites |
| the control and coordination of all life activities | Regulation |
| electrochemical message | Impulse |
| is a change in the external or internal environment which initiates an impulse. Ex: hot stove | Stimulus |
