Synapse and neuralgia

¤ Synapse

* Synapse is the point of contact between the processes of neurons.

They are two-part synapse:

1. Presynaptic neurons transmit nerve impulses toward a synapse.
2. Postsynaptic neuronsConduct nerve impulses away from the synapse.

~ Main types of synapses are two types :

1. Electrical synapsesGap junctions.
2. Chemical synapsesUse neurotransmitters.

~ Types of synapses (based on contacts)Structure of the synapses :

1. Terminal bouton.
2. Presynaptic membrane.
3. Synaptic Cleft.
4. Postsynaptic membrane.
5. Gemmules or spines.

*Functions of the synapse:

- The synapses in the human body are chemical synapses.
- They involve the release of neurotransmitters, which combine with receptors on the post-synaptic membrane and result in the transmission of the impulse.
