WebReceptors are biological transducers that convert energy from both external and internal environments into electrical impulses. They may be massed together to form a sense organ, such as the eye or ear, or they may be scattered, as are those of the skin and viscera. Receptors are connected to the central nervous system by afferent nerve fibres. The … WebMechanisms of Mammalian Pain Systems. Pain receptors (nociceptors) are widely distributed in the skin and other tissues. Nociceptors are free nerve endings of sensory Aδ and un-myelinated C nerve fibers, which respond to tissue damage.
