The Sensory System

TermDefinition
Mechanoreceptors Sensors that detect pressure on the skin, stretching in the muscles, and body movements.
Thermoreceptors Receptors that detect changes in the internal and external changes of the body.
Pain receptors Stimulated by damage or oxygen deprivation to tissues.
Chemoreceptors Stimulated by changes in chemical concentrations. Examples include taste buds and the sense of smell.
Photoreceptors Stimulated by light energy.
Thalamus The sensory relay center for the brain.
Proprioceptors A type of mechanoreceptor that is involved in reflex actions that maintain muscle tone, body equilibrium, and posture.
Cutaneous Receptors Found in the deepest layer of the epidermis and all of the dermis, these receptors give the skin the sensitivity to touch, pressure, pain, and temperature.
Pain Receptors (Nociceptors) There are somatic pain receptors found in the skin and muscles as well as visceral pain receptors that are found in the organs.
Referred Pain Pain from the organs can often be felt in the skin due to the sensations traveling the same route to the spinal cord.
Taste Buds The sensory receptors that are responsible for taste. Taste buds are embedded in the epithelium on the tongue and papillae.
Olfactory Cells Olfactory cells are located on the roof of the nasal cavity and are modified neurons. These cells are responsible for the sense of smell.
