The function of a synaptic knob is to change the action potential that is carried by axons into a chemical message. The chemical message then interacts with the recipient neuron or effector. This process is called synaptic transmission. Axons usually have thousands of terminal branches that each end as a bulbous enlargement called a synaptic knob or synaptic terminal. Synaptic knobs contain several membrane-bounded synaptic vesicles that are 40 to 100 nanometers in diameter. The mitochondria, microtubules and other organelles are located in the synaptic knobs. The neurotransmitter is in the synaptic vesicles. The action potentials that arrive at the synaptic knobs trigger the release of the neurotransmitter into the synaptic cleft.

The synaptic cleft is the small space in between synapses. When a message is propogated from the brain is travels along these synapses until it reaches the desired nerves in order to produce a response. The message travels from the presynaptic terminal of one synapse to the synaptic cleft to the postsynaptic terminal of the next synapse. The synaptic cleft is mainly used to transport neurotransmitters from one synapse to another in order to continue carrying the nerve impulse until it reaches its destination.

At the synaptic knob, the action potential is converted into a chemical message which, in turn, interacts with the recipient neuron or effector. This process is synaptic transmission.

A synapse is a junction between two neurons. ... The neurotransmitters indirectly pass on the impulse from one neuron to another. The large bulge on the presynaptic neuron is the synaptic knob.
