This is a Mind Map Of Sensory Receptor Classification. Through its sensory systems, the human body may get a comprehension of the world. Exteroceptors detect the world directly from the outside (exteroceptors), interoceptors detect information from internal organs and processes (interoceptors), and nociceptors detect a sense of position and load (nociceptors) (proprioception). Sensory receptors can be found in both external and internal organs, including the eyes, ears, nose, and mouth. Each receptor type transmits a separate sensory modality that eventually combines into a single perceptual frame. Specialized mechanisms convert energy into an electrical signal to obtain this information. We'll go over a fundamental overview of sensory systems, with a concentration on sensory receptors, in this report. In EdrawMind community, you can get more templates related to biology or other topics in study, work and life.

CLASSIFICATION OF SENSORY RECEPTOR
Bare dendrites associated with pain, thermal, tickle, itch, and some touch sensations.
ENCAPSULATED NERVE ENDINGS
Dendrites enclosed in connective tissue capsule for pressure, vibration, and some touch receptors.
Receptors cells synapse with first-order sensory neurons; located in retina of eye (photoreceptors), inner ear (hair cells), and taste buds of tongue (gustatory receptor cells).
RECEPTOR LOCATION AND ACTIVATING STIMULI
Located at or near body surface; sensitive to stimuli originating outside body; provide information about external environment; convey visual, smell, taste, touch, pressure, vibration, thermal, and pain sensations.
Located in blood vessels, visceral organs, and nervous system; provide information about internal environment; impulses usually are not comsciously perceived but occasionally may be felt as pain or pressure.
Located in muscles, tendons, joints, and inner ear; provide information about body position, muscle length and tension, position and motion of joints, and equilibrium (balance).
TYPE OF STIMULUS DETECTED
Detect mechanical stimuli; provide sensations of touch, pressure, vibration, proprioception, and hearing and equilibrium; also monitor stretching of blood vessels and internal organs
Detect changes in temperature.
Respond to painful stimuli resulting from physical or chemical damage to tissue
Detect light that strikes the retina of eye.
Detect chemicals in mouth (taste), nose (smell), and body fluids.
Sense osmotic pressure of body fluids.
