Synaptic Transmission Flashcards
What are gap junctions modulated by?!
pH
Calcium ion concentration
Neurotransmitters
What is electrical transmission?!
Direct flow of ions from one neurone to another
What is chemical transmission?!
Flow of a neurotransmitter
What is central synapse an example of?!
Chemical transmission
Does chemical or electrical transmission have cytoplasmic continuity?!
Electrical
Which out of electrical and chemical transmission has a synaptic delay?!
Chemical
Which transmission is unidirectional?!
Chemical
What is the criteria for a chemical messenger to be classes as a NT?!
Synthesised in the neurone
Present in the presynaptic neurone
Mimics a endogenously released transmitter if applied exogenously
Has a specific removal mechanism
Where are peptides synthesised?!
Cell body
Where are amines and amino acids synthesised?!
Synaptic terminal
What are the two types of synaptic vesicles?!
Small clear
Large dense
In synaptic vesicle cycling where are the vesicles targeted?!
Active zones
What does a rise in calcium ions cause?!
Vesicles fuse and release their contents
How is the fused vesicle membrane taken up into the cell?!
Endocytosis
What are the names of the two SNARE proteins?!
Synaptobrevin
Synaptotagmin
