  2. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception. Commonly recognized sensory systems are those for vision ...

  3. Stimulus (physiology) - Wikipedia

    en.wikipedia.org/wiki/Stimulus_(physiology)

    Sensory receptors can receive stimuli from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction.

  4. Sense - Wikipedia

    en.wikipedia.org/wiki/Sense

    External receptors that respond to stimuli from outside the body are called exteroceptors. [4] Human external sensation is based on the sensory organs of the eyes , ears , skin , vestibular system , nose , and mouth , which contribute, respectively, to the sensory perceptions of vision , hearing , touch , balance , smell , and taste .

  5. Sensory neuron - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuron

    External receptors that respond to stimuli from outside the body are called exteroreceptors. [4] Exteroreceptors include chemoreceptors such as olfactory receptors and taste receptors, photoreceptors (), thermoreceptors (temperature), nociceptors (), hair cells (hearing and balance), and a number of other different mechanoreceptors for touch and proprioception (stretch, distortion and stress).

  6. Sensory processing - Wikipedia

    en.wikipedia.org/wiki/Sensory_processing

    Sensory modulation disorder, in which patients seek sensory stimulation due to an over or under response to sensory stimuli. Sensory based motor disorder. Patients have incorrect processing of motor information that leads to poor motor skills. Sensory processing disorder or sensory discrimination disorder, which is characterized by postural ...

  7. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance (proprioception). [2] Mechanosensory information includes that of light touch, vibration, pressure and tension in the skin.

  8. Stimulus modality - Wikipedia

    en.wikipedia.org/wiki/Stimulus_modality

    Multimodal perception is the ability of the mammalian nervous system to combine all of the different inputs of the sensory nervous system to result in an enhanced detection or identification of a particular stimulus. Combinations of all sensory modalities are done in cases where a single sensory modality results in an ambiguous and incomplete ...

  9. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. [1]
