|
Dendrite |
The branches of a neuron that receive messages and conduct impulses toward the cell body |
|
|
Axon |
The extension of a neuron, ending in branching terminal fibers, they which messages pass to other neurons or to muscles or glands |
|
|
Myelin sheath |
A layer of fatty tissue that covers many neurons. It helps increase the speed of neural impulses as the impulse hops from one part of the node to the next |
|
|
Action potential |
A brief electrical charge that travels down an axon. |
|
|
Neurotransmitter |
Chemical messengers that traverse the synaptic gaps between neurons. |
|
|
Synapse |
The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is the _____gap. |
|
|
Anterior region of the brain, bounded by the Central Sulcus and the Sylvian fissure. Involved in speaking and muscle movements as well as in making plans and judgements. |
Frontal lobe |
|
|
Parietal lobe |
Posterior region of the brain behind the frontal lobe and in front of the occipital cortex. It controls somatosensation and spatial understanding. |
