Neurons

Dendrites are branching extensions of:

receive incoming signals for other neurons

What is the function of the dendrites?

dendrites to the cell body to the axon

When transmitting sensory information to the brain, an electric signal within a single neuron travels from:

Action Potential

brief electrical charge that travels down the axon of a neuron

Myelin Sheath

the sped at which a neural impulse travels is increased when the axon is encased by a:

Threshold

the minimum level of stimulation required to trigger a neural impulse

Synapse

junction between a sending neuron and a receiving neuron

Neurotransmitters

chemical passengers released into the spatial junctions between neurons

depression

undersupply of serotonin is most likely linked to

peripheral

the two major divisions of the nervous system are the central and the ___________ nervous systems

reflex

a simple, inborn response to a sensory stimulus is called a

Endocrine System

hormones are chemical messengers of the

brainstem

reticular information is held here

cerebellum

"little brain" attached to the rear of the brainstem

lesion

surgical destruction of brain tissue

EEG

amplified recoding of the waves of electrical activity that sweep across the surface of the brain is known as an

Sensory Cortex

area at the front of the parietal lobes that receives information from the movement of the body parts

Cerebral Cortex

association areas are located in the _______________

plasticity

the capacity of one brain area to take over the functions of another damaged brain area is ___________
