Term
ANS includes
Definition
-sympathetic, parasympathetic,enteric
Term
somatic NS effectors,pathway,NT, effect,damage
Definition
-effectors-skeletal muscle
-pathway-one myelinated motor neuron from CNS to muscle
-NT-Ach
-effect-stimulatory at nicotinic Ach receptors
-damage leads to muscle paralysis and atrophy
Term
autonomic NS effectors,pathway,NT, effect,damage
Definition
-cardiac/smooth muscle and glands
-one myelinated preganglionic neuron from CNS, one ganglionic neuron with unmyelinated postganglionic axon to effector
-Ach and NE (postganglionic only)
-stimulatory or inhibitory
-when damaged, target organs still function but cannot respond to environment
Term
visceral relfexes
Definition
-2 motor neurons
-integration center may be in the brain
Term
control of ANS functioning
Definition
-hypothalamus-main integration center
-other controls from cerebral cortex, reticular formation and spinal cord
Term
hypothalmic control
Definition
-control may be direct or indirect
-a link between emotions and viscera
-center
Term
centers of hypothalmic control
Definition
-heart activity
-BP
-body temp
-water balance
-endocrine activity
-biological drives
-emotional responses
Term
anatomy of sympathetic fibers
Definition
-TL region
-short pregang
-long postgang
-ganglia close to spinal cord
Term
parasympathetic fibers
Definition
-brain and sacral
-long pre
-short post
-ganglia in visceral organs
Term
solely sympathetic
Definition
adrenal gland
Term
role of adrenal medulla
Definition
-some preganglionic fibers pass directly to the adrenal medulla
-upon stimulation, secrete NE and E into blood
-has nicotinic receptors
Term
sweat glands piloerector muscles NT
Definition
Ach
Term
parasympathetic NS effects
Definition
-short lived
-highly localized control over effectors
Term
sympathetic NS effects
Definition
-long lasting
-body wide effects
-because NE and Epi remain in bloodstream and NE stays in synapse longer
