Tympanic Cavity: Tympanic cavity is separated from the outer ear through the tympanic membrane.It’s structure and functions are as follows. Middle Ear: Middle ear comprises Tympanic Cavity, Eustachian Tube and Ear Ossicles. Read More: Difference between Bone and Cartilage Following it, the pinna leads to the opening of the ear canal which is nothing but a small cylindrical tube which creates the passage for the sound vibrations to reach the eardrum. Tympanic Membrane: It consists of umbo which lies in its centre.Following the meatus lies the stratified epithelium which is commonly known as the wax gland. External Auditory Meatus: The folded cartilage helps the ear canals and the ear drums in analysing the sound by receiving them with maybe greater or lower intensity, accordingly.It is mainly known for collecting the sound waves in the funnel-like structure which further transmits the signals to the middle ear. Auricle (Pinna): Another name for the outer ear is pinna which mainly constitutes the rigid cartilage that is covered by the skin, adipose and the fibrous tissues are also included in the existing lobule filled with the blood capillaries.The structure and functions of outer ear are as follows: Outer Ear: The outer ear comprises Auricle, External Auditory Meatus and Tympanic Membrane.All these parts of a human ear have their own specific significance, as mentioned below: In simple words, the human ear is collectively formed by constituting the outer ear, middle ear and the inner ear. Moreover, the entire procedure of recognizing the sound, analysing the vibrations and perceiving the meanings is attributed to the ears. We all know that the brain in human beings is the ultimate unit of processing, thus, on receiving the auditory signals from ears, it perceives the sound and reverts back the output to the ears for complete understanding of the received sound. The working of the human ears could be understood in terms of analysing the surrounding vibrations and sending the assumed signals to the brain. The pitch of the sound, frequency of sound wave, loudness of sound, amplitude of sound wave and the timbre of the sound contribute a major role in detection and interpretation of the sound perceived by human ear.Įars serve to be the most significant part in the human body. In the human body, it basically serves the function of an astounding transducer, that means, it converts the sound energy to mechanical energy and finally to a nerve impulse that is transmitted to the brain. ![]() Human Ear involves the fields of physiology, psychology and acoustics which makes it a complex subject to study.
