Parts Of The Nervous System

Front 1

systems within the PNS

Back 1

afferent and efferent division

Front 2

afferent division

Back 2

part of PNS that transmit sensory information to the CNS and modifies conditions inside and outside the body

Front 3

efferent division

Back 3

division of the PNS that carries commands from the CNS to the body in response to changed conditions and consits of motor functions

Front 4

parts of the efferent division

Back 4

somatic nervous system and autonomic nervous sysyem

Front 5

somatic nervous sysyem

Back 5

controls skeletal muscles and responds to external stimuli, resulting in movement

Front 6

autonomic nervous system

Back 6

controls internal processes such as digestion and heart rate and responds to internal stimuli, controlling the activity of internal organs and glands

Front 7

types of autonomic nerves

Back 7

parasympathetic nervous system and sympatyhetic nervous sysytem

Front 8

parasympathetic nervous system

Back 8

begins at the base of the spinal cord and promotes functions that conserve or restore energy by slowing the heart down to stimulate digestive activity

Front 9

sympathetic nervous system

Back 9

begins along the middle of the spinal cord and prepares organs for stressul situations by speeding up heart rate to stimulate the release of glucose from the liver and inhibiting digestive organs

Front 10

spinal cord

Back 10

collects and transmit info throughout the body

Front 11

four main structures of the brain

Back 11

cerebrum, cerebellum, diencephalon, brain stem

Front 12

cerebrum

Back 12

makes up most of the brain and is involved in conscious thought and memory
- divided into left and right hemispheres, each of which has four lobes

Front 13

lobes of cerebral hemisphere

Back 13

frontal, parietal, occipital, and temporal

Front 14

corpus callosum

Back 14

thick band of axons that connects the two hemispheres of the cerebrum

Front 15

cerebellum

Back 15

coordinates complex motor patterns

Front 16

diencephalon

Back 16

relays sensory info to the cerebellum and controls homeostasis

Front 17

brain stem

Back 17

connects the brain to the spinal cord and is the autonomic center for regulating the heart, lungs, and digestive sysytem

Front 18

learning

Back 18

an enduring, ususally adaptive change in behavior that results from a specific experience in an individual's life

Front 19

memory

Back 19

the retention of learned information

Front 20

synaptic plasticity

Back 20

changes in the nature of the synapse from the molecular basis of learning
