A synapse is a structure in the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to another neuron or the target effector cell. Synapses play a crucial role in the transmission of nervous impulses from one neuron to another.
Chiropractors primarily focus on the nervous system in their practice. Synapses facilitate communication between two neurons through chemical transmission, allowing them to communicate without direct physical contact.
