Dale's principle

Dale's principle states that a neuron (nerve cell) releases the same set of chemicals, called neurotransmitters, at all its connection points (synapses). This means that the chemical signals a neuron sends are consistent, regardless of the target. For example, if a neuron releases a certain neurotransmitter to excite one muscle, it will do the same for all its other connections. This principle helps us understand how neurons communicate reliably within the nervous system, ensuring that signals are transmitted in a predictable and coordinated manner.
