Term
Central Nervous System & Peripheral nervous system
Definition
Two physical systems within the nervous system
Term
central nervous system
Definition
contains the brain and the spinal cord
Term
peripheral nervous system
Definition
contains all other nerve tissue
Term
somatic nervous system and autonomic nervous system
Definition
two functional systems in the nervous system
Term
somatic nervous system
Definition
controls skeletal muscles
Term
autonomic nervous system
Definition
controls smooth muscles, cardiac muscles, and glands
Term
dendrites and axons
Definition
two types of fibers that extend from the cell body of the neruon
Term
dendrite
Definition
carries impulses toward the cell body
Term
axon
Definition
carries impulses away from the cell body. some covered with myelin
Term
sensory neurons
Definition
transmit impulses towards CNS
Term
motor neurons
Definition
transmit impulses away from CNS
Term
connecting neurons
Definition
contact at synapse
Term
cerebrum
Definition
largest part of the brain, responsible fror memory, reasoning and abstract thought, composed mostly of white matter also houses the cerebral cortex, divided into two hemispheres
Term
diencephalon
Definition
contains the thalamus, hypothalamus, and pituitary gland
Term
thalmus
Definition
receives sensory information, directs info to proper portion of cortex
Term
hypothalamus
Definition
controls pituitary gland, serves as link between endocrine and nervous system
Term
brainstem
Definition
contains midbrain and pons and medulla obolongata
Term
midbrain
Definition
contains reflex centers for improved vision and hearing
Term
pons
Definition
contains fibers that connect different regions of the brain

thrombosis
Definition
formation of blood clot in vessel, often in carotid artery. sudden blockage caused by traveling obstruction called embolism
Term
aneurysm
Definition
localized dilation of vessel
Term
multiple sclerosis
Definition
patchy loss of myelin with hardening tissue in CNS
Term
parkinson disease
Definition
failure of midbrain neurons to secrete dopamine
Term
