| A | B |
|---|
| Receptors | recieves stimulus, initiates impulse |
| Neuron | nerve cell, transports message |
| Effector | muscle or gland |
| Impulse | electrochemical message |
| Stimulus | dhange in environment: initiates impulse |
| Regulation | control and coordination of all life functions |
| Cell Body | contains nucleus of neuron |
| Dendrites | detect stimuli enerate impulse |
| Axon | transmits impulse aay from cyton |
| Synapse | gap between terminal branches and dendrites |
| Sensory neurons | impulses from receptor to spinal cord and brain |
| Motor neurons | impulses from brain and spinal cord to effector |
| Interneurons | relay impulse from one neuron to another |
| Nerves | makes up nervous system |
| sensory nerves | nerve containing the axons of a sensory neuron only |
| Motor nerve | nerve containing the axons of the motor neurons only |
| Neurotransmitters | chemical secreted by by the terminal branches |
