Sensory organs

What is Sensory organs?

Sensory organs meaning There are five major senses of the body: vision, taste, smell, hearing and touch. The body; however, has literally millions of sensory organs (or receptors), each associated with one or more nerves whose function is to convert the energy of a stimulus into a sensation or reflex.Receptors detect changes in the external and internal environment and initiate the responses necessary for adjusting the body to these changes. It is the dendrite portion of the sensory neuron which serves as the receptor of a sense organ. Receptors may be classified according to their locations1. Exteroceptors: surface receptors. Located in the skin, mucosa, eye, and ear.2. Visceroceptors (interoceptors): Located in the walls of the blood vessels in the stomach, intestines, and various other organs.3. Proprioceptors: Located in muscles, tendons, joints, and the internal ear.
