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.

Urinary System. Anatomy. Male. Anatomy. Two kidneys (filters). Renal pelvis/one per kidney (funnels urine into ureters). Two ureters (to bladder). One bladder (storage). One urethra (exit). Nephro. = kidney. 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. The function of vertebrate hearing is served by a surprising variety of sensory structures in the different groups of fish, amphibians, reptiles, birds, and mammals. This book discusses the origin, specialization, and functional properties of sensory hair cells, beginning with environmental constraints on acoustic systems and addressing in detail the evolutionary history behind modern structure and function in the vertebrate ear. Taking a comparative approach, chapters are devoted to each of the vertebrate groups, outlining the transition to land existence and the further parallel and independent adaptations of amniotic groups living in air. The volume explores in depth the specific properties of hair cells that allowed them to become sensitive to sound and capable of analyzing sounds into their respective frequency components. Evolution of the Vertebrate Auditory System is directed to a broad audience of biologists and clinicians, from the level of advanced undergraduate students to professionals interested in learning more about the evolution, structure, and function of the ear.
