    It is one of the traditional five senses; partial or total inability to hear is called hearing loss. In humans and other vertebrates, hearing is performed primarily by the auditory system : mechanical waves , known as vibrations are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal ...

    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 , hearing , touch , taste , smell , balance and visceral sensation.

    The brain interprets head orientation by comparing these inputs to each other and other input from the eyes and stretch receptors in the neck, thereby detecting whether the head is tilted or the entire body is tipping. [6] Essentially, these otolithic organs sense how quickly you are accelerating forward or backward, left or right, or up or ...
