Abstract: geometric marks and shapes used to depict a specific object or operations. Anatomy and physiology . Sense organ. Ears are a pair of complex sensory organs located in the both sides of the head at approximately eye level. Ears are housed in the . temporal bones. Each ear is divided into 3 parts – . EGR 412.

Felipe Fernandez. Drew Link. Andrew Schmitz. Introduction. Watched a hypnotist named Michael C. Anthony. . The hypnotized participants would do some funny and crazy things once they heard a snap of a finger. Hearing. Language. Sensory Receptors. A . receptor. Is a cell, often a specialized neuron, . Suited by its structure and function to respond to a particular form of energy, such as sound.. Function. : . Overview. Capabilities of the Auditory System. What does the auditory system do and how well does it do it?. Hearing Sensitivity. The faintest sound that can be detected by the human ear is so weak that it moves the ear drum a distance that is equivalent to . Review the anatomy of ears. Correctly order the steps of inner ear response. Explain the brain mechanism for sound localization. Draw the central auditory pathway. Understand the common audiometric/special hearing tests. Like light, sound travels in waves and like vision, in order to hear, we first need to receive the sensory input of the waves and then convert them into neural impulses sent to, and processed by, the brain. into local. receptor . potentials.

Learning Goal Three: Understand how the auditory system registers sounds and how it connects with the brain to perceive it.. The Nature of Sound and How We Experience It. Sounds waves are vibrations in the air that are processed by the auditory system.. We . associate pitch (the high or low quality of a sound) with . frequency. . Pitch . can vary due to factors other than frequency, such as the intensity or context of a stimulus.. Most frequencies are systematically encoded by the auditory system through . Roberto Bresin.

The ear converts changes in pressure in the air to changes in the electrical activity of neurons. . The . human ear can detect sound frequencies between 20 and 20 000 Hz.. Anatomists distinguish the outer ear, the middle ear, and the inner ear.
