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
|
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
|
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
|
Definition
-brain and sacral -long pre -short post -ganglia in visceral organs |
|
|
Term
|
Definition
|
|
Term
|
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
|
|
Term
parasympathetic NS effects |
|
Definition
-short lived -highly localized control over effectors |
|
|
Term
|
Definition
-long lasting -body wide effects -because NE and Epi remain in bloodstream and NE stays in synapse longer |
