impulses causing the release of a chemical signal and its diffusion across the synapse.

process of neural transmission starts
neural networks
Yes, neurotransmitters diffuse across the synaptic cleft to transmit a neural signal; the actual neural impulse(spike) occurs when the neuron fires in response to a sufficiency of signals received.

if u know, tell me please!!! im doing the same assignment too :P if u know, tell me please!!! im doing the same assignment too :P
The process by which inhibitory and excitatory post-synaptic potentials summate and control the rate of firing of a neuron.

Action potential
Neural transmission within the ganglia is cholinergic (acetylcholine) and the vasoconstrictive neurons release epinephrine at the blood vessels. So blocking neural transmission within the ganglia will reduce vasoconstriction.
