They vary in length and can extend from a few micrometers to several feet in certain cases. Let us learn more about axon definition, anatomy, physiology, clinical significance, and history below. Watch this vid about axons: Biology definition: Axons...
Interrupted by World War II, Hodgkin and Huxley returned to their biophysical studies at the Marine Biological Station in Plymouth, UK, following up their original description of the squid action potential with a longer paper in the Journal of Physiology in 1945. These studies and those of their...

The studies on the anatomy of the nervous system of cephalopods carried out in the late 1930s at the Stazione Zoologica di Napoli by Sereni and Young (Sereni and Young, 1932; Young, 1934, 1936, 1939), brought to the attention of researchers the unusually large diameter of the neuronal ...
Despite substantial advances in knowledge on the anatomy and physiology of cardiac nerves that contribute to therapeutic responses, there are still many gaps that need to be filled as neuromodulation treatments move away from pharmaceuticals and non-specific treatments to more guided and specific therapeu...

Neurotransmission is the process of transferring these signals from one cell to another. This process stimulates the membrane of a neuron, and that neuron needs to signal another neuron, essentially working in a chain of neurons, in order for the information to travel quickly to the brain. ...
