nerve		clusters of cell bodies of neurons in the CNS
sensors		a collection of axons of motor neurons , dentriets of sensory neurons
Neurotransmitters		substance that transmits nerve impulses across a synapse
cranialnerves		the region where neurons communicate with each other
nerves		bundles of axons of neurons haveing the some function and destination
centers		a collection of cell bodies of neurons
receptors		neurons are supported and protected by specliazed tissue known as
Neuroglia		nerves that carry impulses to and from the spinal cord
adequatestimulus		nerves that carry impulses to and from the brain
synapse		particular form of energy to which the receptor responds is its
ganglia		the sensors that sense changes in the internal and external enviroment
Neuron		sense changes in the internal
effectors		the organs that respond to impulses from the CNS
