This document provides an introduction to neurohumoral transmission, which involves nerves transmitting messages across synapses and neuroeffector junctions by releasing chemical messengers. The process includes impulse conduction down the nerve, transmitter release at the junction, the transmitter acting on the postjunctional membrane to cause postjunctional activity, and termination of the transmitter's action.

10. Neurohumoral transmission
• Neurohumoral transmission implies:
• That nerves transmit their message across
synapses and neuroeffector junctions by the
release of humoral (chemical) messengers.

11. Steps
• Impulse conduction
• Transmitter release
• Transmitter action on postjunctional
membrane
• Postjunctional activity
• Termination of transmitter action
