General properties of sensory systems • External stimulus, • Sensory receptor, • Afferent sensory neuron, • Integration RECEPTORS: are transducers that convert stimuli into electrical signals. Receptors are structured to be sensitive to one type of stimulant (Fig. 10-1) • the simplest receptors are somatosensory (Figure 10-1a) • Receptors are divided into five major groups based on the type of stimulus (Table 10-2) 1.Chemoreceptors 2.Mechanoreceptors 3.Photoreceptors 4.Thermoreceptors 5.Nociceptors...
