Function/DefinitionNervous System PartWhere in the Nervous System
P: Impulse moves toward cell body (hopping over myelin in PNS)
Consists of the brain and spinal cord
produces myelin sheath around CNS nerve fibers
Collects, integrates, and evaluates smell data
Understanding language *similar to another area*
Pain, Temperature, Meissner corpuscle (touch/texture), Pacinian corpuscle (pressure)
I: Na+ ions into neuron
Consists of cranial and spinal nerves
Division that carries info TO body tissues/organs from CNS
Heart rate; blood pressure; breathing; swallowing; vomiting; not crocodiles
Sends impulses to skeletal muscles
Collects, integrates, and evaluates taste data
Connects the Left and Right hemispheres of Cerebrum
Reflex centers for vision and hearing
Subdivision that deals with voluntary/conscious control of body
Rapid, predicatble and involuntary response to stimuli
R: charge on membrane returns to normal when K+ moves out of neuron
'Rest and Digest'
Receives and interprets information from sensory receptors
Connects sensory and motor neurons
Inflammation of meninges
Subdivision that deals with involuntary control of body
'Fight or Flight'

Collects sight data
Function/DefinitionNervous System PartWhere in the Nervous System
Creates new memories; spacial memory, navigation
Failure of cerebrum to form
3 connective tissue membranes that cover brain and spinal cord
Fiber tracts such as Corpus Callosum
Planning action and movement, abstract thought, emotion and judgment
Forms myelin sheath in PNS
D: change in polarity of cell membrane

Plans carrying out complex motor sequences
Substance that continues a nerve impulse from an axon to a dendrite
Spiderlike phagocyte; disposes of debris
Star-shaped; braces neurons and controls chemical environment of brain
Grooves in brain
Result of excessive alcohol consumption during pregnancy
Improper formation of the vertebra, leading to a pinched spinal cord
