The gaps between Schwann cells found at regular intervals in peripheral system
neurons are called
synaptic clefts
axon terminals
nodes of Ranvier
myelin sheaths

The gaps between Schwann cells, known as nodes of Ranvier, play a vital role in the rapid transmission of nerve impulses. These interruptions in the myelin sheath allow electrical signals to jump from one node to the next, significantly speeding up the conduction along the axon, a process termed saltatory conduction.

Interestingly, the discovery of nodes of Ranvier dates back to the 19th century, highlighting the evolution of our understanding of neuronal function. Originally identified by the French scientist Jules François Félix Antoine Fohrel in 1850, these nodes have become crucial in the study of neuroscience, shedding light on how signals travel throughout the nervous system!
