idegközvetített

Idegközvetített is a Hungarian term that translates to "nerve-mediated" or "transmitted by nerves." It refers to a process or signal that is relayed through the nervous system. This can encompass a wide range of biological functions, from simple reflexes to complex cognitive processes.

In the context of physiology, idegközvetített describes the transmission of electrochemical impulses along neurons, the fundamental units of the nervous system. When a stimulus is detected, it triggers an electrical signal that travels down the neuron's axon. This signal is then passed on to the next neuron or effector cell (like a muscle or gland) at a synapse, often through chemical messengers called neurotransmitters.

For example, the sensation of touching a hot object is an idegközvetített process. Sensory receptors in the skin detect the heat and send a signal via peripheral nerves to the spinal cord and brain. The brain interprets this signal as pain and heat, and then sends motor commands back through motor neurons to the muscles, causing you to withdraw your hand. This entire chain of events, from initial detection to motor response, is idegközvetített.

The term can also be applied more broadly to describe any phenomenon that relies on the nervous system for its operation or communication. This includes things like learned behaviors, emotions, and the coordination of bodily movements. Understanding how processes are idegközvetített is crucial for comprehending the intricate workings of the nervous system and its role in maintaining health and facilitating interaction with the environment.
