The distance across a nerve synapse is 20 nanometres or 2x10-8 metres
It is most definitely a synapse.
no
nuerotransmitters
neurons?
no
The reactions having a great time leaping across synapses is not known well and people take estimates only.
Neurons are responsible for transmitting a stimulus across a synapse. The electric potential of the neuron is sensitive to changes in the resting state and sets off electric transmissions.
A synapse in a simple reflex action is a junction between two neurons where signals are transmitted. In a reflex action, when a stimulus triggers a sensory neuron, it sends a signal across a synapse to a motor neuron, which then causes a rapid response from a muscle or gland.
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
