synapses 1 unfinished

where do electrical synapses occur

gap junctions

what are gap junctions made of

membrane-bridging channel called connexons

what do connexons do

permit ions and small polar molecules to pass through cells

what are advantages of electrical transmission

no synaptic delay, and are minimally susceptible to foreign ligands

what are found within synaptic vesicles

neurotransmitters

what is an active zone in a presynaptic ending

specialized area where neurotransmitters are released into the synapse

what causes the NT to be released into the presynaptic terminal

depolarization

where are small NTs synthesized

nerve terminal

where are large NTs synthesized

cell body

where are small NTs packaged

light vesicles

where are large NTs packaged

dense core vesicles

are small NTs transported

no

are large NTs transported

yes by microtubules

where are small NTs stored

near the pre-synaptic membrane

where are large NTs stored

far from the pre-synaptic membrane

neurons contain how many NTs

one small and one large

what is exocytosis

the process of NT release
