TERM 1 Sensory Neurons DEFINITION 1 transfers signals for receptors to the central-nervous system TERM 2 Interneurons DEFINITION 2 CNS neurons TERM 3 Motor Neurons DEFINITION 3 transfers signal from the CNS to the Effectors (glands, muscles) TERM 4 anatomy of the neuron DEFINITION 4 dendrites- receive the impulse and transfer it to the cello bodycell body- nucleus of the cell and associated cytoplasm which then transfers the signal to th axonaxon- longest part of the neuron TERM 5 action potential DEFINITION 5 wave of depolarization down a nerve fiber as measured electricallythis happens due to a change in the membrane permeability as a result of a stimulus which causes the influx of Na+ which results in a brief positive charge TERM 6 resting potential DEFINITION 6 the polarized state of the neuron resulting from the difference in concentration TERM 7 major events of action potential DEFINITION 7 resting potentialthresholdpeak action potential (depolarization) inside of the neuron is positiverepolarization (Na ions escape)hyperpolarization (over escape of Na ions)return to resting potential TERM 8 synapse DEFINITION 8 the gap at which the terminal axon endings of one neuron are in close position with another neuron TERM 9 how does a synapse work? DEFINITION 9 -action potential travels down axon to synaptic knob-then the release of neurotransmitter substances is stimulated from the synaptic vesicles from the pre synaptic membrane b the process of exocytosis- the transmitter substance travels across the synapse until it reaches the postsynaptic membrane of the second neuron where the receptor cells are simulated by the transmitter substance and another action potential is generated in the receiving neuron TERM 10 adrenergic DEFINITION 10 adrenaline is the neurotransmitter
