The role of sensory receptors in the skin
WebbThey respond to tissue injury or potentially damaging stimuli by sending nerve signals to the spinal cord and brain to begin the process of pain sensation. Nociceptors are equipped with specific molecular sensors, which detect extreme heat … WebbSensory receptors stimulated during coitus or masturbation are essentially located in the penile skin, prepuce, and glans. Sensory inputs are conveyed to the upper sacral and lower lumbar segments of the spinal cord via the dorsal nerve of the penis, a sensory branch of the pudendal nerve (Fig. 2).A relatively sparse sensory innervation of ductus deferens, …
