NEURAL PROCESSES
16
NEURAL IMPULSE:The ______ _______ that flows down the axon is started by an action potential that changes the resting potential of the neuron
RESTING POTENTIAL:The _______ _________ of the neuron refers to its electric charge when at rest
GLIA:Provide support, protecting and nourishment for neurons
NEURONS:Are the information processors of the nervous system - they receive, integrate and transmit information
INSULATORS:Glia cells can act as "__________" for neurons and help avoid cross-talk
SENSORY:Type of neuron that receives information from the outside world
MOTOR NEURON:Type of neuron that communicates with other parts of the body
INTERNEURON:Type of neuron that communicates with other neurons
DENDRITES:The branched fibres of neurons that receive incoming signals
AXON:The extended fibre of a neuron through which nerve impulses travel from the soma to the terminal buttons
SOMA:The cell body of a neuron, containing the nucleus and cytoplasm
MYELIN SHEATH:Insulating material that surrounds axons and increases the speed of neural transmission
TERMINAL BUTTONS:The bulb-like structures at the branched endings of axons that contain vesicles filled with neurotransmitters
SYNAPSE:The gap between one neuron and another
ALLORNONELAW:A rule that the size of the action potential is unaffected by increases in the intensity of stimulation beyond the threshold level
NEUROTRANSMITTERS:The chemical messengers released from neurons that cross the synapse from one neuron to another, stimulating the postsynaptic neuron
