Web11 apr. 2024 · The extracellular matrix (ECM) is the scaffold in which cellular components of all tissues are embedded. It constitutes roughly 40% and 20% of the total brain volume of the developing and adult brains, respectively [].While brain-specific forms of the ECM were originally described by Camillo Golgi in 1882 [], several recent studies are unraveling the … Earlier forming cells from this region can become non-pain sensing receptors, either proprioceptors or low-threshold mechanoreceptors. All neurons derived from the neural crest, including embryonic nociceptors, express the TrkA, which is a receptor to nerve growth factor (NGF). Meer weergeven A nociceptor ("pain receptor" from Latin nocere 'to harm or hurt') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals to the spinal cord and the … Meer weergeven Nociceptors were discovered by Charles Scott Sherrington in 1906.
