PPT-ANATOMY OF AUDITORY SYSTEM

Ear 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. 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 – . 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.

The text is designed to provide comprehensive coverage of the anatomy and physiology of the central and peripheral auditory systems. Readers will benefit from the important link between science and clinical practice, with integrated clinical correlates found in each chapter. Key Features: Presents balanced coverage of both the peripheral and central auditory systems Integrated clinical correlates establish the link between science and practice Substantial use of review articles and secondary sources enhances general understanding Numerous anatomical sketches and photographs supplement learning New to this Edition: A newly designed color interior and many full color images provide increased readability A new chapter providing an overview of normal development of the auditory system, plasticity of the central auditory system, and aging effects on the peripheral and central auditory systems A number of new illustrations New and updated information on synaptic ribbons, neuropharmacology of cochlear function, cryoloop cooling, and the vascular network of the brainstem Updated references, review articles, and readings Access to a PluralPlus companion website that includes a PowerPoint image bank The Auditory System: Anatomy, Physiology, and Clinical Correlates, Second Edition is an essential text for graduate programs in audiology and a valuable reference for audiologists at any stage of their career.
