Nerve physiology

Nerve physiology. Physiology of Nerves. There are two major regulatory systems in the body, the nervous system and the endocrine system. The endocrine system regulates relatively slow, long-lived responses The nervous system regulates fast, short-term responses. Neuron structure.

Overview: Lines of Communication

Overview: Lines of Communication. The cone snail kills prey with venom that disables neurons. Neurons are nerve cells that transfer information within the body. Neurons use two types of signals to communicate: electrical signals (long-distance) and chemical signals (short-distance).
