They are nerve endings and provide information on mechanical pressure, position, and deep static touch features, such as shapes and edges. A free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain. They function as cutaneous nociceptors and are essentially used by vertebrates to detect noxious stimuli that often result in pain. gabby\u0027s woodbury menu
