afferent neurons

Afferent neurons are nerve cells that transmit signals from sensory organs and tissues to the brain and spinal cord. They play a crucial role in detecting stimuli such as touch, temperature, pain, and pressure, and carrying this information inward so the nervous system can interpret it. For example, when you touch something hot, afferent neurons send a message from your hand to your brain, alerting you to the sensation. These neurons are essential for sensing the environment and enabling appropriate responses to internal and external stimuli.
