Peripheral somatosensory system

WebThe peripheral somatosensory system bestows mammals with a diverse repertoire of sensory modalities: gentle touch, mechanical pain, itch, thermosensation, and proprioception. The cells and molecules that transduce many of these stimuli have already been characterized. WebGlutamate is the most common neurotransmitter in both the central and the peripheral nervous system. Glutamate is present in all types of neurons in sensory ganglia, and is released not only from their peripheral and central axon terminals but also from their cell bodies. Consistently, these neurons express ionotropic and metabotropic receptors, as …
