Ears: Facts, Function & Disease Hearing. The external ear, also called the auricle or pinna, is the loop of cartilage and skin that is attached to outside of the head. It works much like a megaphone. Sound is funneled through the external ear and piped into the external auditory canal, according to Nebraska Medicine.

Auricle (anatomy) Due to its anatomy, the pinna largely eliminates a small segment of the frequency spectrum; this band is called the pinna notch. The pinna works differently for low and high frequency sounds.

About cancer of the outer ear Another important part of the ear is the bone that surrounds and protects the ear. The outer ear is the part of the ear we can see. It protects the rest of the ear and helps us collect sound. There are 3 parts to the outer ear: the ear flap or pinna. the ear canal (meatus) the eardrum (tympanic membrane)

4. The human auditory system 4.1 Ear anatomy. The ear can be seen as three parts: the outer ear, the middle ear and the inner ear - each with a dedicated function. The outer ear consists of the ear shell (pinna) and the auditory canal. Its function is to guide air pressure waves to the middle ear- with the ear shell increasing the sensitivity of the ear to the front side of the head, supporting front/rear localisation of audio signals.

- of organism. For example, Quercus garryana is the scientific name for garry oak. The name of a genus is one word, such as Quercus (the oaks), and can be used alone, whereas the name of any species must include the generic name and the species name, such as Quercus garryana.he ordering of diversity into a recognizable pattern is the basis of any classification scheme. Studies of pre-European indigenous cultures have shown that there is a distinct correlation between the use of language and the ordering of organisms into a few accessible categories that are hierarchical in form.

THE GLOSSARY OF Hearing begins when sound waves that travel through the air reach the outer ear or pinna, which is the part of the ear you can see. The sound waves then travel from the pinna through the ear canal to the middle ear, which includes the eardrum (a thin layer of tissue) and three tiny bones called ossicles.

How We Hear Finally, it helps us to appreciate front-back sound localization. The other structure of the outer ear is the external ear canal. The outer two-thirds of this canal has a cartilaginous framework, and the inner one-third is bony. The skin of the external ear canal is continuous with the skin of the pinna.

Ear The pinna consists of the curving outer rim called the helix, the inner curved rim called the antihelix, and opens into the ear canal. The tragus protrudes and partially obscures the ear canal, as does the facing antitragus. The hollow region in front of the ear canal is called the concha.

What are the functions of the Eustachian tube? The primary function of the Eustachian tube is to ventilate the middle ear space, ensuring that its pressure remains at near normal ambient air pressure. The secondary function of the Eustachian tube is to drain any accumulated secretions, infection, or debris from the middle ear space.

- The fleshy part of ear, the pinna, collects the sound. The sound wave then travels through the auditory canal which funnels the sound to the ear drum causing it to vibrate. Th…e ear drum then amplifies the sound by vibration of bones. It is in the middle ear where sound energy is converted into mechanical energy.

- Objectives: The external ear is the entry way to the auditory receptors of the inner ear. Thus, it plays an important role in normal hearing. Because it is a structure that is frequently examined in the clinic, understanding of its functions is important.At the end of this section you should be able to: 1. Describe the two functions of the external ear, including the effects of the pinnae and ear canals on incoming sound waves.ecause it is a structure that is frequently examined in the clinic, understanding of its functions is important.

Auricle physiology of hearing. The outer ear directs sound waves from the external environment to the tympanic membrane. The auricle, the visible portion of the outer ear, collects sound waves and, with the concha, the cavity at the entrance to the external auditory canal, helps to funnel sound into the canal. Because of its small size and virtual immobility, the auricle in humans is less useful in sound gathering and... Read More.

- Often the entire organ is considered the ear, though it may also be considered just the visible portion. In most mammals, the visible ear is a flap of tissue that is also called the pinna (or auricle in humans) and is the first of many steps in hearing. Vertebrates have a pair of ears placed somewhat symmetrically on opposite sides of the head. This arrangement aids in the ability to localize sound sources.

Auricle (anatomy) While some of the sounds that enter the ear travel directly to the canal, others reflect off the contours of the pinna first: these enter the ear canal after a very slight delay. This delay causes phase cancellation, virtually eliminating the frequency component whose wave period is twice the delay period.

How the ear works The Outer Ear. The outer ear is made up of the pinna, which is the flesh part you can see on the side of your head, and the ear canal, the route along which sound travels. The outer ear ends at the eardrum, a layer that divides the outer and middle ear. The Middle Ear.

The Human Ear The outer ear serves to collect and channel sound to the middle ear. The middle ear serves to transform the energy of a sound wave into the internal vibrations of the bone structure of the middle ear and ultimately transform these vibrations into a compressional wave in the inner ear.he three parts of the ear are shown below. The Outer Ear The outer ear consists of an earflap and an approximately 2-cm long ear canal. The earflap provides protection for the middle ear in order to prevent damage to the eardrum.

Sensory Systems/Auditory Anatomy The folds of cartilage surrounding the ear canal are called the pinna. Sound waves are reflected and attenuated when they hit the pinna, and these changes provide additional information that will help the brain determine the direction from which the sounds came.he sound waves enter the auditory canal, a deceptively simple tube. The ear canal amplifies sounds that are between 3 and 12 kHz. At the far end of the ear canal is the tympanic membrane, which marks the beginning of the middle ear.
