Document Summary
In short, discovered first neurotransmitter: direct and nondirect synapses, directed synapse - more usual - site of release and contact are in close proximity. Right across from each other, tight connection: nondirected synapse - site of release and contact are separated by some distance (e. g. hormones and neuromodulators) - string of beads axon terminals. Neurons released into the air - diffuse throughout brain (wander around: neurotransmitter molecules. No (no need - created where it"s released - axon terminal) By microtubules to the button (40cm/day) (down axon) Receptors (proteins) are specific to a given nt: nt molecules wander to dendrites of next neuron - receptors and nt are. Lock and key system: ligand - a molecule that binds to another. An nt is a ligand of its receptor: there are multiple receptor subtypes for a given nt (usually in different brain areas).
