Ch 16 and 17 Lec 2 - Nerve Tracts and the ANS Flashcards
two effects of sympathetic division
increases alertness, energy, euphoria, increased muscle tone
the central nervous system stimulates blank neurons
preganglionic
preganglionic neurons always release blank
ach
preganglionic neurons are known as blank synapse
cholinergic
preganglionic neurons stimulate blank neurons
postganglionic
postganglionic neurons release blank
adrenaline
adrenergic receptor that responds to both epinephrine and norepinephrine
alpha
adrenergic receptor alpha targest blank muscle
smooth
adrenergic receptor that only responds to epinephrine
beta
cholinergic receptors respond to blank
ach
in sympathetic nervous system, preganglionic fibers are blank and postganglionic fibers are blank
short, long
synapsing occurs in sympathetic chain or blank ganglia
collateral
preganglionic fiber releases blank
ach
postganglionic fibers release blank
norepinephrine
sympathetic division prepares body for blank
emergencies
sympathetic division effects are blank and persistent
widespread
division that originates from neurons in midbrain, pons, medulla, and sacral region of the spinal cord
parasympathetic
parasympathetic division exit the CNS via blank nerves and blank nerves
cranial, sacral
