Task: Question Answering
Input (English): Context: Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear., The organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea. Described as "a masterpiece of cellular micro-architecture", this highly varied strip of epithelial cells allows for transduction of auditory signals into nerve impulses' action potential. Transduction occurs through vibrations of structures in the inner ear causing displacement of cochlear fluid and movement of hair cells at the organ of Corti to produce electrochemical signals., Sense of balance or equilibrioception is one of the physiological senses related to balance. It helps prevent humans and animals from falling over when standing or moving. Balance is the result of a number of body systems working together: the eyes (visual system), ears (vestibular system) and the body's sense of where it is in space (proprioception) ideally need to be intact. The vestibular system, the region of the inner ear where three semicircular canals converge, works with the visual system to keep objects in focus when the head is moving. This is called the vestibulo-ocular reflex (VOR). The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation or balance. Visual signals sent to the brain about the body's position in relation to its surroundings are processed by the brain and compared to information from the vestibular, visual and skeletal systems., A reflex action, differently known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. Scientific use of the term "reflex" refers to a behavior that is mediated via the reflex arc; this does not apply to casual uses of the term "reflex"., The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system., A sense is a physiological capacity of organisms that provides data for perception. The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive psychology (or cognitive science), and philosophy of perception. The nervous system has a specific sensory system or organ, dedicated to each sense., The cochlea (khlias, meaning "spiral" or "snail shell") is the auditory portion of the inner ear. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.5 turns around its axis, the modiolus.
A core component of the cochlea is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating fluid chambers in the coiled tapered tube of the cochlea. The name is derived from the Latin word for "snail shell", which in turn is from the Greek  "kokhlias" ("snail, screw"), from  "kokhlos" ("spiral shell") in reference to its coiled shape; the cochlea is coiled in mammals with the exception of monotremes., Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria., The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts:, The bony labyrinth (also osseous labyrinth or otic capsule) is the rigid, bony outer wall of the inner ear in the temporal bone. It consists of three parts: the vestibule, semicircular canals, and cochlea. These are cavities hollowed out of the substance of the bone, and lined by periosteum. They contain a clear fluid, the perilymph, in which the membranous labyrinth is situated., The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex., A reflex arc is a neural pathway that controls a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex is carried out. Analysis of the signal takes place after action has been taken., The visual system is the part of the central nervous system which gives organisms the ability to process visual detail, as well as enabling the formation of several non-image photo response functions. It detects and interprets information from visible light to build a representation of the surrounding environment. The visual system carries out a number of complex tasks, including the reception of light and the formation of monocular representations; the buildup of a nuclear 
binocular perception from a pair of two dimensional projections; the identification and categorization of visual objects; assessing distances to and between objects; and guiding body movements in relation to the objects seen. The psychological process of visual information is known as visual perception, a lack of which is called blindness. Non-image forming visual functions, independent of visual perception, include the pupillary light reflex (PLR) and circadian photoentrainment., Proprioception, from Latin "proprius", meaning "one's own", "individual", and "capio", "capere", to take or grasp, is the sense of the relative position of neighbouring parts of the body and strength of effort being employed in movement., The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three partsthe outer ear, middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. The middle ear includes the tympanic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing. The ears of vertebrates are placed somewhat symmetrically on either side of the head, an arrangement that aids sound localisation., Monotremes are basal mammals that lay eggs (Prototheria) instead of giving birth to live young like marsupials (Metatheria) and placental mammals (Eutheria). The only surviving examples of monotremes are all indigenous to Australia and New Guinea, although there is evidence that they were once more widespread. The existing monotreme species are the platypus and four species of echidnas. There is currently some debate regarding monotreme taxonomy., The vestibular system , in most mammals , is the sensory system that provides the leading contribution about the sense of balance and spatial orientation for the purpose of coordinating movement with balance . Together with the cochlea , a part of the auditory system , it constitutes the labyrinth of the inner ear in most mammals , situated in the vestibulum in the inner ear ( Figure 1 ) . As movements consist of rotations and translations , the vestibular system comprises two components : the semicircular canal system , which indicate rotational movements ; and the otoliths , which indicate linear accelerations . The vestibular system sends signals primarily to the neural structures that control eye movements , and to the muscles that keep an animal upright . The projections to the former provide the anatomical basis of the vestibulo - ocular reflex , which is required for clear vision ; and the projections to the muscles that control posture are necessary to keep an animal upright . The brain uses information from the vestibular system in the head and from proprioception throughout the body to understand the body 's dynamics and kinematics ( including its position and acceleration ) from moment to moment ., Subject: vestibular system, Relation: instance_of, Options: (A) action (B) architecture (C) base (D) behavior (E) bone (F) brain (G) class (H) classification (I) complex (J) component (K) data (L) evidence (M) extinct (N) formation (O) hearing (P) humans (Q) information (R) keep (S) may (T) name (U) neural pathway (V) operation (W) organ (X) part (Y) perception (Z) position ([) process (\) reference (]) reflex (^) relation (_) science (`) sense (a) sensory system (b) sound (c) space (d) species (e) system (f) taxonomy (g) three (h) variety (i) vision (j) wall (k) will
