Neuron junctions.: Synapses are junctions between neurons, or nerve cells. Nerves transmit signals throughout the body, & synapses are gates where chemical signals are transduced to electrical ones. Synapses may be simply described as excitatory or inhibitory, and often depends on the neurotransmitter involved. For example, excitation of the heart and inhibition of the gut are part of the fight or flight response. ...Read more
Electro-chemical: Many neurotransmitters, both excitatory and inhibitory play a major role in nerve-nerve communication in brain and spinal cord. Simplest model is the Neuro-muscular junction, where at the tip of the axon, there is a release of acetylcholine, which reaches the postsynaptic muscle receptor, causing muscle contraction. ...Read more
Anatomy of neuron: All these are anatomy ( and physiology ) of neuron or nerve cell. 'dendrite' is branched projections of neuron which receives electrical signals, when a group of neurons are clumped together the site is called 'ganglion', and the ' synapse' is the junction of neuron that communicates with the target cell ( or other neuron) by releasing a chemical transmitter to activate the other cell. ...Read moreSee 2 more doctor answers

Can you tell me how l-dopa effect the actions of neurotransmitters at the synapse in Parkinson's patients?
Explanation: Although Parkinson's is a multi-neurotransmitter deficiency disorder, the main focus involves a dopamine deficiency within the basal ganglia. L-DOPA is a precursor, which is transformed within the body to dopamine after ingestion, and supplements the deficiency present in the substantia nigra which improves communication with areas such as putamen and globus pallidus. ...Read more
