Is The Eardrum Part Of The Outer Ear – The ear is a complicated structure with these main parts. The outer part consists of the pinna and the ear canal. The middle ear consists of the eardrum and an air-filled space behind the eardrum. It contains the auditory nerve. Air in the middle ear is exchanged through a tube that connects it to the back of the nose. This is called the Eustachian tube. The inner ear is where the actual hearing organ is located. This is called the cochlea. It also contains the organ of balance or the vestibular apparatus. The cochlea and the organ of balance are connected to the brain by a nerve that allows you to interpret sounds and detect changes in your balance. The diagram below shows the different parts of the ear.
The figure below shows what a normal eardrum looks like. The membrane is thin enough to see the shadows of the structures behind the drum. If you move the cursor over the photo, some of the main structures will be highlighted.

There are only 5 symptoms that can arise as a result of ear problems. These are:

The ear can usually be easily examined with an instrument called an otoscope. This is a special battery powered torch designed to be placed in the ear canal. The picture below shows an ear being examined with an otoscope.
An ear specialist often also uses a microscope to more closely examine the eardrum and ear canal. The extra magnification that the microscope provides makes accurate diagnosis much easier. An ear being examined under a microscope is shown below.
In addition to examining your ear, anyone with significant ear symptoms will have a complete examination of the balance system. In some situations, it is also necessary to perform a complete neurological examination of the head. Required exams will be explained before they take place.
In many patients with ear problems, it is important to have their hearing checked. This test is called an audiogram and is performed by an audiologist. The test involves playing tones in the ear at different frequencies (measured in kilohertz) and lowering the volume of the sound (measured in decibels shortened to dB) to a level at which it can only be heard. This is called the hearing threshold. This process is repeated at a number of different frequencies and the thresholds are plotted on a graph. A typical normal audiogram is shown below. In this case, the hearing thresholds are all better than 20 dB, which is the limit for normal. Thresholds for the right ear are marked in red and thresholds for the left ear are marked in blue.
How You Hear
If there is hearing loss, then the thresholds will be below 20dB. The figure below shows the loudness and frequency of some sounds every day.
Sometimes it is also necessary to carry out other types of tests after the first consultation. This may include some tests or more detailed balance function scans, which may be a magnetic resonance imaging (MRI) scan or a computed tomography (CT) scan. You will be told what to expect when you need to have these tests.
All three parts of the ear can have problems. The vast majority of problems are related to infection or inflammation of the ear.
If the ear begins to discharge, this usually means that an infection is present. The infection usually affects the middle ear, but sometimes it can happen if there is an infection of the outer ear. Inflammation of the outer ear, however, more often causes pain and is therefore dealt with in more detail under the heading ‘Earache’. In this section, the focus is on middle ear infections.
Ear: Anatomy, Facts & Function
There are two main types of middle ear infection (also called otitis media). The most common is called acute otitis media. The other type is called chronic otitis media. The main difference in terms of symptoms is the duration of symptoms. Acute otitis media usually lasts a few days. Chronic otitis media lasts more than 3 months. The underlying cause of the two types is different.
Acute otitis media is the most common cause of ear infections in children, although it can affect adults. It is usually a viral infection, but it can be bacterial. You usually have a high temperature and you generally don’t feel well. There is usually an earache on one side. There may also be discharge from the ear. Young children cannot tell you that they are in pain. Instead they usually pull the ear. The flow chart below shows how acute otitis media develops, click on the picture to enlarge.
It is often possible to tell what type of ear infection has occurred from the symptoms, and it is almost always possible to make a diagnosis by looking into the ear with an otoscope. The table below shows the common characteristics of different types of ear infection, click on the image to view a larger version: Your ears are extraordinary organs. They collect all the sounds around you and then translate this information into a form that your brain can understand. One of the most remarkable things about this process is that it is completely mechanical. Your sense of smell, taste and sight all involve chemical reactions, but your hearing system is based only on physical movement. Your ears are responsible for collecting sounds, processing and sending sound signals to your brain. And that’s not all – the ears also help you keep your balance. The ear consists of three different sections: the outer ear, the middle ear, and the inner ear. All these parts work together so you can hear and process sounds.
The outer ear is called the pinna or ear (pronounced: of-ih-kul). This is the part of the ear that people can see. The main task of the outer ear is to collect sounds. The outer ear also includes the ear canal, where wax is produced. Earwax protects the canal. Earwax contains chemicals that fight infections that can damage the skin in the ear canal. It also collects dirt to help keep the ear canal clean.

After sound waves enter the outer ear, they travel through the ear canal and make their way to the middle ear. The middle ear’s main job is to receive those sound waves and turn them into vibrations that are delivered to the inner ear. To do this, it needs the ear drum, which is a thin piece of skin that is as tight as a drum. The ear drum separates the outer ear from the middle ear and the eardrums (ah-sih-kulz). What are bones? They are the three smallest and most delicate bones in your body. They include: malleus (mah-lee-us), which is attached to the ear drum and means “hammer” in Latin incus (in-kus), which is attached to the malleus and “anvil” in Latin will it says stapes (stay-peez), the smallest bone in the body, which is attached to the incus and means “brace” in Latin. When sound waves reach the eardrum, they cause the eardrum to vibrate. When the ear drum vibrates, it moves the small bones – from the hammer to the anvil and then to the stirrer. These bones help sound move during its journey to the inner ear.
Sound enters the inner ear as vibrations and enters the cochlea (ko-klee-uh), a small, curly tube in the inner ear. The cochlea is filled with fluid, which is set in motion, like a wave, when the umbilicus vibrates. The cochlea is also lined with tiny cells covered with tiny hairs. When sound reaches the cochlea, the vibrations (sound) cause the hairs in the cells to move, generating nerve signals that the brain interprets as sound.
Ears do more than hear. They also keep you balanced. In the inner ear, there are three small loops above the cochlea called the semicircular canals. Like snails, they are also filled with fluid and have thousands of microscopic hairs. When you move your head, the fluid in the semicircular canals also moves. The fluid moves tiny hairs, which send a nerve message to your brain about the position of your head. In less than a second, your brain sends messages to the right muscles, so you keep your balance. Sometimes the fluid in your semicircular canals continues to move after you’ve stopped moving. Your brain is getting two different messages and is confused about the position of your head. Once the fluid in the semicircular canals stops moving, your brain gets the right message and you regain your balance. Sometimes the balance does not return and you may need to see a specialist for more help.
Audiologists can examine all parts of the auditory system with a variety of tests that measure hearing and hearing loss and other auditory/vestibular disorders. Specialized equipment is used to measure many different mechanisms of the auditory and vestibular systems. Keeping your hearing safe from loud noises and excessive noise can help maintain good hearing for an enjoyable life! The outer ear consists of
