Section 1

Question Answer
what system controls the brain and spinal cordcentral nervous system (CNS)
what system controls the whole body except the braoin and spinal cordperipheral nervous sytem (PNS)
what system controls the skeletal musclesSomatic nrevous system (SNS)
what system controls the GI tractEnteric nervous system (ENS)
what system will control cardiac and smooth muscles associated with ENSAutonomic nervous system (ANS)
what system controls fight of flightSympathetic (SNS)
what system controls rest and digestparasympathetic (PSNS)
Major structures of the PNSnerves, ganglia, enteric plexuses, receptors
how many spinal nerve are there31 pairs
how many cranial nerves are there12 pairs
what are nervesbundles of axons, CT, and BV
what is gangliamasses of nervous tissue - primarily cell bodies
what are enteric plexusesthey are in GI Tract and help regulate the digestive system
what do receptors domonitor changes in the internal and external environments
3 functions of the nervous systemsensory funtion, motor function, integrative function
what is sensory functionsense changes in the internal/external environments
what is the integrative functionanalye sensory information, and make decisions regarding appropriate behaviors
what is a motor functionrespond to stemuli by initiating action

Section 2

Question Answer
what is the primary function of the cell body, axonsto sent information away
what is the primary function of the cell body, dendriteto recieve information
wwhat possess electrical excitability, the ability to respond to a stimulus and convert it into a nerve impulseneurons
what is an axonnerve fibers, carries nerve impulses to anothe nerve syste, muscle fiber, or a gland cell
what is a dendritethe recieving or input portions of the neurons
neuron classificationssensory (away from stimulus), interneuron (neuron to neuron), motor (to rhe effector)
what is neurolgiasupporting cells, involved in nervous transmission
neuralgia in CNSastrocytes, oligodendrocytes, microglai, ependymal cells
neuralgia in PNSschwann cells, satelite cells
2 types of astrocytes and functionsprotoplasmic astrocytes and fibrous astrocytes, (support, form blood-brain berriers, maintain chemical envi for action potential, memory, regulate brain development in embreyo)
oligodenrites and schwan cells (function)form and maintain myelin sheath (CNS- oligodendrite) (PNS-schwann cells)
microglia (function)removes cell debris, microbes, and damaged tirssue
ependymal cells (function)produce CSF, helps form blood-cerbospinal flud berrier, ciliated
satelite cells (function)provide support and regulate exchange of material
what is white mattermostly mylinated axons
what is grey mattercell bodies, unmylinated axons, dendrites, neurolgia
