Nervous 2 Flashcards
an involuntary reaction in response to a stimulus applied to the periphery and transmitted to the CNS.
Reflexes
neuronal pathway by which relex occurs.
Reflex atc
have only four components because the reflex does not
involve interneurons.
Simple reflex arc
involves synapses of two or more neurons.
Polysynaptic reflex
Two neuronal pathways
Converging pathway
Diverging pathway
two or more neurons synapse with the same
postsynaptic neuron.
Converging pathway
the axon from one neuron divides and synapses
with more than one other postsynaptic neuron
Diverging pathway
In most people this area is located in the left cerebral cortex.
Speech area
located in the parietal lobe. Responsible for understanding speech
Sensory speech (Wernicke’s) area
located in the frontal lobe. Responsible for
producing speech.
Motor (Broca’s) speech area
a recording device which records brain’s electrical
activity.
Electroencephalogram
Memory divided in three stages
Working memory
Short and long term memory
lasts only a few second to minutes
Working memory
can be retained for few minutes to few days
Short term memory
can be retained permanently.
Long term memory
