Neuron | Afferent
This physical heat is a "stimulus" that hits your receptors. Immediately, you spring into action. You don't just carry a message; you become the message by converting that heat into a tiny electrical pulse called an . The Long Journey Inward
: These are your "ears," specialized branches that pick up the initial signal from the sensors.
You reach the gates of the spinal cord (the "dorsal horn") and release chemical messengers called across a tiny gap known as a synapse . You've done your part. You have successfully informed the brain that something is dangerously hot. afferent neuron
Within milliseconds, the brain processes your report and sends a command back out via your counterparts—the —who "Exit" headquarters to tell the muscles to pull the hand away. Why You Matter
: Unlike many other cells, yours often sits in a little roadside station called a ganglion , just outside the spinal cord, keeping you fueled for the trip. Delivering the News This physical heat is a "stimulus" that hits your receptors
As an afferent neuron, your path is strictly "inward-bound" toward the (the brain and spinal cord). You are structured perfectly for this:
: This is your high-speed highway. The electrical pulse zips down this long fiber at incredible speeds. The Long Journey Inward : These are your
Without you, the body would be "blind" to its environment. You aren't just for emergencies like heat; you are the reason we can: Afferent Neuron Cell Types - CZ CELLxGENE CellGuide
