This essay explores the mechanisms that are behind nociceptive pain and focuses on how sensory cells can convert harmful stimuli into electrical signals. Nociceptive pain arises from the activation of nociceptors, that are specialized receptors found in the skin, muscles, joints, and organs. These receptors are able to detect noxious stimuli, like extreme temperatures or mechanical injuries and alerts the body to potential harm. This process is called transduction. Sodium and calcium ion channels in nociceptors open to the cell in the response to such stimuli and causes depolarization. If the threshold is reached, then action potential is generated and transmitted along the neuron to the spinal cord and the brain.
Frequency of the action potentials reflects the intensity of the stimuli and the stronger the stimuli than it can produce more signals and greater pain perception. The brain then processes the signals and triggers its protective reflexes! Ciara’s wonderful drawing showcases just what her essay has described so well! It was a joy reading and learning how the how nociception relates to certain stimuli and how it can generate action potential!
