INTERNEURON Meaning and
Definition
-
An interneuron is a specialized type of nerve cell found exclusively within the central nervous system (CNS), that serves as a link between sensory neurons and motor neurons. Also termed as association neurons or relay neurons, interneurons are primarily responsible for processing and relaying information within the CNS, facilitating communication between various regions of the brain and spinal cord.
Interneurons play a crucial role in integrating and interpreting sensory input, as well as coordinating motor output. They receive signals from sensory neurons and transmit this information to motor neurons, allowing for the execution of appropriate physiological responses. Additionally, interneurons may also communicate with other interneurons, forming complex neural pathways.
These neurons possess several distinguishing features that enable their function. They typically have shorter axons compared to sensory or motor neurons, allowing for faster transmission of signals across shorter distances. Additionally, interneurons are characterized by numerous branching dendrites, facilitating receipt of multiple signals simultaneously.
The intricate network of interneurons allows for complex information processing within the CNS, regulating various physiological processes, including reflexes, movement, sensation, and cognition. Dysfunction or damage to interneurons can potentially lead to neurological disorders, affecting sensory perception, movement coordination, or mental processing.
In summary, interneurons are a vital component of the CNS, acting as intermediary cells that enable communication and integration of signals within the complex neural network of the brain and spinal cord.
Common Misspellings for INTERNEURON
Etymology of INTERNEURON
The word "interneuron" is derived from the Greek roots "inter", meaning "between", and "neuron", meaning "nerve". The term was coined in the mid-20th century to describe a specific type of neuron that functions as a connector or relay between other neurons in the central nervous system. Interneurons facilitate communication between sensory neurons, motor neurons, and other interneurons, playing a crucial role in information processing and coordination within the nervous system.
