fundamental units of the nervous system are nerve cells call
Nervous system contain not only neurons, but also other cells called
Glial cells do the following functions
They nourish nerve cells
They help repair damage that mi ght occur to neurons
The main reason the neurons can commucate over relatively great distances within the body is the fact that neurons contain:
a variety of transmitters
Branch like fibers extending in clusters from the neuron's cell body are called
compared your forearm, hand and fingers to a neuron: what would the dendrites be in comparison
an axon is
long, tubelike structure extending from a neuron's cell body
Comparing your forearm, hand, and fingers to a neuron, the axon would be your
Dendrite is to axon as
Which structures are expecially important for communication between one neuron and another
axons and dendrites
Terminal buttons are found at the ends of
What is the correct sequence arranges nervous system structures from the most general to the most specific
neuron > axon> terminal button
Which of the following sequences accurately reflects the route folllowed by nerve implulses when one neuron communicates with another
What is like coating over electrical wires that is performed in the nervous system
Action pootentials are
Action potentialscan travel at different speeds along different axons,
Along a given axon come action potentials are stronger than others
Some neurons can fire action potential at faster rates than other neurons can
Action potential follow what law?
all or none
As an action potential occurs the neuron's electrical charge:
changes from negative to positive
