Front 1

Neuron

Back 1

a nerve cell

Front 2

Dendrite

Back 2

the branches of a neuron that receive messages and conduct impulses toward the cell body

Front 3

Axon

Back 3

the extension of a neuron, ending in branching terminal fibers through which messages pass to other neurons or to muscles or glands

Front 4

Myelin sheath

Back 4

layer of fatty tissue that covers many neurons

Front 5

action potential

Back 5

a brief electrical charge that travels down an axon

Front 6

neurotransmitter

Back 6

chemical messengers that traverse the synaptic gaps between neurons

Front 7

synapse

Back 7

the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron

Front 8

frontal lobe

Back 8

anterior region of the bran, bounded by the central sulcus and the sylvian fissure. involved with speaking and muscle movements as well as in making plans

Front 9

perietal lobe

Back 9

posterior region of the brain behind the frontal lobe and in front of the occipital cortex

Front 10

temporal lobe

Back 10

lower region of the brain near the ears and below the sylvian fissure. controls hearing and complex visual recognition

Front 11

occipital lobe

Back 11

region of the rear brain that controls primitive vision - edges, movement, color, etc

Front 12

central sulcus

Back 12

groove separating frontal from parietal lobe

Front 13

sylvian fissure

Back 13

groove separating frontal from temporal lobe

Front 14

brainstem

Back 14

at the base of the brain and at the top of the spinal cord

Front 15

cerebellum

Back 15

structure blow the occipital cortex involved in motor coordination and primitive learning

Front 16

thalamus

Back 16

a little larger than an almond and found in the center of the brain, this structure receives nearly all incoming sensory messages and then relays them to appropriate cortical lobes

Front 17

limbic system

Back 17

a group of structures deep in the brain, primarily the temporal lobe, involved in emotion and learning

Front 18

hippocampus

Back 18

structure in deep temporal lobe, part of the limbic system, involved in memory formation

Front 19

amygdala

Back 19

structure in deep temporal lobe, part of the limbic system, involved in the regulation of stress and aggression

Front 20

bottom-up processing

Back 20

using what we actually see when we look
