Document Summary
In order for the body to maintain homeostasis it is necessary for the body to detect changes in the external environment so it can react appropriately in order to maintain its internal environment. The body has several sensory systems that allow it to detect these external changes rapidly including the somatosensory (touch) system, the visual system, the auditory and vestibular system, the olfactory (smell) system, and the gustatory (taste) system. Transduction of environmental information is how information from the external environment is turned into language the brain understands action potentials. In order for the brain to know what is happening outside the body, environmental stimuli (energy) like light, heat, touch, or sound must first be detected by sensory receptors, which then converts the information into action potentials. In order for the brain to consciously perceive an environmental stimulus, that stimulus must be detected by a sensory receptor.
