Psychology

the neuron extension that passes messages through its branches to other neurons or to muscles or glands

a fatty tissue layer segmentally encasing the axons of some neurons; enables vastly greater transmission speed as neural impulses hop from one node to the next

a neural impulse; a brief electrical charge that travels down an axon

the level of stimulation required to trigger a neural impule

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

tiny gap at the synapse junction is call

chemical messengers that cross the synaptic gaps between neurons

a neurotransmitter's reabsorption by the sending neuron

the cell;s life support center

electrical signal traveling dow the axon

receive messages from other cells

form junctions with other cells

passes messages away from the cell body to other neurons, muscles, or glands

this neurotransmitter enables muscle action, learning, and memory

this neurotransmitter influences movement, learning, attention, and emotion

this neurotransmitter affects mood, hunger, sleep, and arousal

this neurotransmitter helps control alertness and arousal

this neurotransmitter is a major inhibitory neurotransmitter

this neurotransmitter is a major excitatory neurotransmitter; involved in memory

the brain's naturally occurring opiates

the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems

the brain and spinal cord are components of what

the sensory and motor neurons that connect the central nervous system to the rest of the body

bundled axons that form neural "cables" connecting the central nervous system w muscles, glands, and sense organs

neurons that carry incoming information from the sensory receptors to the brain and spinal cord

neurons that carry outgoing information from the brain and spinal cord to the muscles and glands

neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs

the division of the peripheral nervous system that controls the body's skeletal muscles

the part of the peripheral nervous system taht controls the glands and the muscles of the internal organs

the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations

the division of the autonomic nervous system that arouses

the division of the autonomic nervous system that calms

nervous system that controls self-regulated action of internal organs and glands

nervous system that controls voluntrary movements of skeletal muscles

the lobe involved in speaking and muscle movements and in making plans and judgments

portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position

part of the cerebral cortex lying at the back of the head; includes areas that receive info from the visual fields

portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving info primarily from the opposite ear

part of the brain w ultimate control and info-processing center

part of the brain relays messages between lower brain centers and cerebral cortex
