Do eyeballs have pain receptors
WebPain receptors consist of free nerve endings that are stimulated when tissues are damaged, and adapt little, if at all. Found all over the body except in the nervous tissue of the brain. Many stimuli affect pain receptors such as chemicals and oxygen deprivation. How pain receptors are stimulated is poorly understood. Nociceptors develop from neural-crest stem cells. The neural crest is responsible for a large part of early development in vertebrates. It is specifically responsible for development of the peripheral nervous system (PNS). The neural-crest stem cells split from the neural tube as it closes, and nociceptors grow from the dorsal part of this neural-crest tissue. They form late during neurogenesis. Earlier forming cells from this region can become non-pain sensing receptors, eit…
