|
Dendrite
|
the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
|
|
|
Axon
|
extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands
|
|
|
Action Potential
|
a neural impulse; a brief electrical charge that travels down an axon
|
|
|
Threshold
|
the level of stimulation required to trigger a neural impulse
|
|
|
Synapse
|
the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.
|
|
|
Neurotransmitters
|
chemical messengers that traverse the synaptic gaps between neurons. The influence whether or not a neuron will generate a neural impulse
|
|

What does the Motor strip responsible for?
What is the Sensory strip responsible for? |
it controls voluntary movements.
it registers and processes body touch and movement sensations |
|
|
Association areas
|
are areas of the cerebral cortex that are not involved in primary motor or sensory functions; instead, they are involved in higher mental functions such as learning, remembering, thinking, and speaking.
