BIOLOGY OF THE MIND FIFTH EDITION
©Glial cells. Answer:non neural cells that serve various functions in the
nervous system
©Soma. Answer:the cell membrane that encloses the cell body
©Dendrites. Answer:branching extensions of the neuron that receives
inputs from other neurons
©Spines. Answer:little knobs attached by small necks to the surface of
the dendrites where the dendrites receive inputs from other neurons
©Axon. Answer:a single process that extends from the cell body
- the output of the neuron
©Synapse. Answer:where two neurons come into close contact so that
chemical or electrical signals can be passed from one cell to the next
,©Axon collaterals. Answer:Branch of axon that can transmit signals to
more than one cell
©Myelin. Answer:fatty substance that axons are wrapped in layers of
©Presynaptic. Answer:when a neuron's axon makes a connection onto
other neurons
©Postsynaptic. Answer:when other neurons make a connection onto a
neuron's dendrites
©Neuronal Signaling. Answer:when neurons receive, evaluate, and
transmit information
©ion channels. Answer:are proteins with a pore through their centers
that allow certain ions to flow down their concentration gradients
©ion pumps. Answer:use energy to actively transport ions across the
membrane against their concentration gradients- from one region of low
concentration to regions of higher concentration
©permeability. Answer:the extent to which a particular ion can cross the
membrane through a given ion channel
, ©electrical gradient. Answer:A force that develops when a charge
distribution across the neuronal membrane develops such that the charge
inside is more positive or negative than the one outside. Electrical
gradients result from asymmetrical distributions of ions across the
membrane.
©electrotonic conduction. Answer:
©Glial cells functions:. Answer:providing structural support and
electrical insulation to neurons and modulating neuronal activity
©We have equal amounts of. Answer:glial cells and neurons
©neurons main function. Answer:the main communication unit of the
brain
get- process- send
©axon terminals. Answer:where the neuron transmits the signal to other
neurons or other cell types
©transmission occurs at the. Answer:synapse
©resting membrane potential. Answer:-70mV
