More Information
The synaptic knob plays a critical role in the transmission of neural signals. Within these knobs are vesicles filled with neurotransmitters which, when released, allow for communication between neurons and other cells.
Tips
Students often confuse the synaptic knob with the entire synapse. The synapse includes the synaptic knob, the synaptic cleft, and the postsynaptic membrane.
