The synaptic cleft.
synaptic terminal
The impulse has to cross over a synapse to another neuron or an effector.
Neurotransmitter
Neurotransmitter.
It is when neurotransmitters are released form one neuron and travel across the synapse, which is a gap between two neuron, in order to stimulate the second neuron

A synapse is the gap between a neuron.
The impulse has to cross over a synapse to another neuron or an effector.
there are 2 - one between the sensory and relay neurones; the other between the relay and motor neurones.
A synaptic knob is a tiny bulge at the end of a terminal branch of a presynaptic neuron's axon!
A reflex arc.
Summarized below are the 5 major components of the reflex arc: 1. Receptor 2. Afferent (sensory) neurons 3. Association neuron 4. Efferent (motor) neurons 5. Effector
Because it is a small gap between the axon of one neuron and the receiving dendrite of another neuron.
Neurotransmitter
Neurotransmitter.
Motor neurons are able to create a response in effector organs, muscles and glands by sending signals to them.
