ANATOMY

Detailed explanation-1: -Receptors are the organs that sense sight, smell, taste, touch and sound. It thus involves eyes, nose, tongue, skin and ears. Muscle is not a receptor.

Detailed explanation-2: -According to the activating stimulus sensory receptors can be classified into electromagnetic receptors (photoreceptor, thermoreceptor), mechanoreceptors (hearing, touch, balance, osmoreceptor), and chemoreceptors (odorant receptor, gustatory receptor).

Detailed explanation-3: -Chemoreceptors respond to chemicals in taste and smell and in internal changes. Thermoreceptors respond to temperature changes. Mechanoreceptors respond to physical forces in touch, hearing, and pressure. Photoreceptors respond to light.

Detailed explanation-4: -What are the different types of sensory neuron receptors? You can classify cells based on their morphology, location or by what kind of stimulus they respond to. It is common to group them into 5 classes: mechanoreceptors, thermoreceptors, nociceptors, electromagnetic receptors and chemoreceptors.
