Cards

Term
how does the NS regulate homestasis
Definition
regulates & coordinates cellular activity w/neurotransmitters & hormones
Term
CNS
Definition
brain & spinal chord
Term
PNS
Definition
cranial & spinal nerves
Term
sensory function
Definition
allows body to detect stimuli
Term
integrative function
Definition
NS translates sensory info as impulses traver over interneurons
Term
motor function
Definition
response is sent to effectors over motor neurons
Term
3 functional characteristics of neurons
Definition
excitability
conduction
secretion
Term
neuron
Definition
carries nervous impulses
lacks centrioles
contains nissl bodies & neurofibrils
Term
soma
Definition
contains nucleus; neuron processes extend from it
Term
dendrites
Definition
neuron processes that possess receptors; responds to environment, conducts impulses towards soma
Term
axons
Definition
neuron processes extend from soma @ axon hillock
Term
function of axons
Definition
carry impulses away from soma
Term
teledendria
Definition
terminate in synaptic knobs containing synaptic vesicles filled w/ neurotransmitters
Term
multipolar neurons
Definition
1 axon & mult. dendrites
Term
bipolar neurons
Definition
1 axon & 1 dendrite
Term
unipolar neurons
Definition
1 process that branches to form an axon & dendrites
Term
sensory neurons function
Definition
carries impulses from receptors to CNS
Term
montor neuron function
Definition
carry impulses from CNS to effectors
Term
inter-neurons function
Definition
connect sensory & motor neurons and located in CNS
Term
glial cells
Definition
support neurons; do NOT carry nervous impulses
Term
oligodendrocytes
Definition
form myelin w/in CNS
Term
astrocytes
Definition
connects neurons to capillaries; cover brain surface; form blood-brain barrier; provide framework of CNS
Term
ependymal cells
Definition
line spaces and aid in production & circulation of cerebrospinal fluid
