hermoärsykkeille refers to nerve impulses. These are electrical signals that travel along nerve fibers, also known as axons, which are the long, slender projections of nerve cells, or neurons. Nerve impulses are the fundamental means by which the nervous system communicates information throughout the body. They are generated when a neuron receives a stimulus that causes a change in its electrical potential. This change, if it reaches a certain threshold, triggers an action potential, which is the nerve impulse itself.
The transmission of a nerve impulse is an electrochemical process. Within a neuron, the impulse is electrical,
Nerve impulses are crucial for a wide range of bodily functions, including sensory perception (seeing, hearing,
