mechanoreceptors of the inner ear.

Anatomy and Function of the Ear.

The pinna is a projecting elastic cartilage covered with skin. Definition The ear is a complex sensory system able to capture, distribute, and transmit sound vibrations, before turning them into electrical signals to send to the brain. WebMD's Ear Anatomy Page provides a detailed image and definition of the ear as well as an overview of ear-related health problems. Human ear - Human ear - The physiology of balance: vestibular function: The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium.

It helps you hear and keep your balance.

The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes. Just as the eyes turn certain wavelengths of light into images, so the ear turns certain wavelengths of vibration into sounds. Neurons within the ear respond to simple tones, and the brain serves to process other increasingly complex sounds. Function of the ear The outer ear is composed of two parts: the pinna (partially visible) and the ear canal.

The function of the tympanic membrane (eardrum) is to transmit sound waves from the environment into sound vibrations that are picked up by the middle ear auditory ossicles.

The hair fibres in the cochlea are all connected to the auditory nerve and, depending on the nature of the movements in the cochlear fluid, different hair fibres are put into motion.

In this article we will discuss about the structure and functions of human ear. An average adult is typically able to detect sounds ranging between 20 and 20,000 Hz. The proper function of the Eustachian tube is critical for optimization of middle ear sound transmission and health maintenance. WebMD's Ear Anatomy Page provides a detailed image and definition of the ear as well as an overview of ear-related health problems. These will change the "sound" into electrical energy and sent it to the brain for

The inner ear has two main functions. The main function of the ear is to transmit the "sound" to the. The ear can be divided into three parts, which work together, they are the outer ear, the middle ear and the inner ear.

The Eustachian tube, also known as the pharyngotympanic tube, is a narrow fibrocartilaginous duct that connects the middle ear to the nasopharynx.
The human ear, like that of other mammals, contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements.


The ability to detect higher pitch sounds decreases in older humans.

The pinna captures external sound vibrations and forwards them to the eardrum via the ear canal.

Basic Anatomy of the Ear. It does this through a system of many parts, including: The outer ear, which includes the complex shell that is the visible ear we see on the outside of our heads. Function.

The function of the auditory nerve is to transmit signals from the internal ear to the brain.

Inner ear function. It comprises a pinna, external auditory meatus (canal) & tympanic membrane. Its most prominent outer ridge is called the helix. Study of the structure and function of various parts of the ear is needed to understand the different types of hearing loss and the methods used in preventing or treating hearing loss. The parts of the inner ear are attached but work separately to do each job.
