Study Notes
Interneurons Overview
- Interneurons act as connectors between sensory neurons and motor neurons, facilitating communication within the nervous system.
- They play a crucial role in reflexes, processing information, and coordinating motor responses.
Location of Interneurons
- Found exclusively in the brain and spinal cord, residing entirely within the central nervous system (CNS).
- Outnumber all other types of neurons combined, indicating their importance in neural circuitry.
Functions of Interneurons
- Responsible for the analysis of sensory input, enabling quick and effective responses.
- Coordinate motor output, ensuring smooth and accurate movement based on sensory information.
Classification of Interneurons
- Divided into two main types:
- Inhibitory interneurons: reduce neuronal activity and prevent over-excitation.
- Excitatory interneurons: enhance neuronal activity and promote signal transmission.
