The term neural junction is a synonym for the word synapse, which is a structure that allows neurons to communicate with each other. Synapses are composed of two parts: the presynaptic neuron and the postsynaptic neuron. The presynaptic neuron releases neurotransmitters, which then bind to receptors on the postsynaptic neuron, allowing for the transmission of electrical signals. Synapses are essential for the functioning of the nervous system, as they allow neurons to send and receive information.
