Web★ Drugs exert actions by affecting neurotransmission (process by which a signal or other activity in a neuron is transferred to an adjacent neuron or other cell) ★ Neuron: functional unit of the nervous system Interneuronal synaptic junction consists of the presynaptic element and the postsynaptic receptor area ★ Synapse: points of contact between … WebNeural Transmission. The function of a neuron is to transmit information within the nervous system. Neural transmission occurs when a neuron is activated, or fired (sends out an electrical impulse). Activation (firing) of the neuron takes place when the neuron is stimulated by pressure, heat, light, or chemical information from other cells.
