Which two statements are true about Synaptic Transmission?

Neurotransmitters are hormones released by glands as a result of puberty.

Synapses are gaps in the brain where information can be stored.

Action potential is the electrical signal which causes the synaptic vesicles to merge with the cell membrane and release the chemicals out into the synapse.

Synaptic Transmission is a myth

Inhibition is...?

The end result of the combination of postive and negative ions inside the cell.

When some neurotransmitters stop excitation by stopping the build up of positive ions in the cell - they do this by selectively causing the opening or closing of ion channels thus denying access for sodium (positively charged) or allowing chloride (negatively charged) in to the membrane.
