Excite (/ɪkˈsaɪt/) is a term commonly used in the medical field, particularly in neurology and physiology, to describe the process of increasing the activity or efficiency of a certain organ or tissue.
Etymology
The term "excite" originates from the Latin word "excitare", which means to rouse or stir up.

Usage in Medical Context
In the field of neurology, the term "excite" is often used to describe the stimulation of neurons. When a neuron is excited, it fires an action potential, which is an electrical signal that travels down the neuron and leads to the release of neurotransmitters.
In physiology, the term can be used to describe the stimulation of muscles. When a muscle is excited, it contracts and generates force.
