Lymph nodes are bean-shaped glands present throughout the body. They store the fluid and nutrients and help in flushing out the waste from the body. Lymph nodes produce antibodies which fight off infections and foreign bodies. When the nodes accumulate foreign substances, they swell and get enlarged. Swollen lymph nodes can be a scary thing. Swollen lymph nodes behind the ears can be just as scary because they are usually associated with a health issue.
A swollen lymph node behind your ear could be caused by many things. In fact, there are 10 specific causes of swollen lymph nodes behind the ear.
What causes swollen lymph nodes behind the ears?Add background to gif online
There are a number of causes of swollen glands behind the ear. A lump behind the ear is caused by a range of issues including infections, acute or blunt force injuries, autoimmune disorders, cancer, German measles, an abscessed tooth, an allergic reaction, influenza or rhino viruses, strep throat, or lipoma. Bacterial, fungal, or viral infections like mononucleosis can cause a lump behind the ear.
Lymph nodes produce antibodies to fight the infections and as more antibodies are produced the lymph nodes swell. Swelling behind the ear can be a result of a blow behind the ear.
Also, accident or injury to the head or neck will cause swelling behind the ears due to the accumulation of antibodies. Autoimmune diseases breakdown the immune system causing swelling behind the ear.
Lumps behind the ear can be due to cancerous tumors that can lead to lymphoma or leukemia. Because cancer cells are foreign bodies, they accumulate in the nodes. Rubella virus causes a viral infection known as German measles. The virus causes swollen lymph nodes behind the ear. An abscess is a pocket that forms around the tooth allowing germs and pus to gather in the pocket.
The germs and pus are objects foreign to the body which causes swollen lymph nodes behind the ear. Allergies, often experienced during the spring when pollen counts are high, can cause swollen lymph nodes behind the ear. Allergens are also foreign substances to the body which may accumulate in the nodes causing swelling behind the ear. Influenza A or B also known as the flu and Rhino virus also known as the common cold can cause a lump behind the ear. As your body fights these viruses, the immune system gets inflamed as it produces increased amounts of white blood cells which accumulate in your lymph nodes causing swollen lymph nodes behind the ear.
Strep throat is common in children and spreads from child to child through crawling on a dirty floor or sharing infected toys. Streptococcus bacteria gather in the throat and as the body fights the bacteria. White blood cells and antibodies accumulate in the lymph nodes causing swollen glands behind the ear.

A hearing care professional determines with the help of a hearing test whether or not a hearing loss is present. If no hearing loss is present, you won't need any further help. In the case where a hearing loss is present, the kind and degree of your hearing loss is determined individually for each ear and entered in an audiogram.
Hearing is graphed on an audiogram, a graph of the softest sounds you can hear. The graph is laid out like a piano keyboard, with low to high frequencies low to high pitches going from left to right, So once your graph is filled in x represents the left ear, o the rightHearing is NOT measured in percentages.
The decibel dB, or dB HL is a logrithmic scale. Physically, every 6 dB increase represents a doubling of sound pressure level. Perceptually, every 10 dB increase sounds twice as loud. Every increase of 10 decibels 10 dB sounds twice as loud. From here on, the assumption is that you have a sensorineural hearing loss that you have nerve damage to the inner ear. Nerve damage, unless sudden, is permanent. For conductive hearing losses, see your otolaryngologist your ENT physician.
For sudden hearing losses, see your otolaryngologist within a day. If you cannot, get an immediate medical evaluation elsewhere. If you have a standard audiogram, highlight the 20 dB line that crosses the graph from left to right.
If all of the X's for the left ear and all of the 0's for the right ear fall above the line you just drew, you have normal hearing. If anything is below that 20 dB line, you have a hearing loss. Your hearing loss is classified according to how far down the graph the marks go, and in what freqencies the loss occurs.

Here are some common hearing losses Every octave -- every interval across the top -- forms a square with every 20 decibel 20 "dB" change going down. Some other common variations include putting the left and right ears on different graphs, and using a different interval for the frequencies across the top. If you have this kind of graph, the right half of the pattern of your hearing test will be stetched out, as shown below, on the right:.

How to Read Your Hearing Test Hearing is graphed on an audiogram, a graph of the softest sounds you can hear.The sinuses are hollow spaces in the skull and the face bones around your nose.
The name sinus comes from the Latin word sinuswhich means a bay, a curve, or a hollow cavity. The sinuses are part of your nose and respiratory system. They connect to your nasal passages in a complex network of air flow and drainage passages.
As you breathe in air through your nose and mouth, it moves through the sinus passages. The sinuses also produce mucus that coats and lubricates your nasal passages and the sinuses themselves. Both air and mucus flow through your sinuses and drain into your nose, through tiny openings called ostia or singular, ostium.
Little hairs called cilia help the mucus move through the sinus cavities. The mucus from the sinuses drains into your nasal passages and then down the back of your throat to be swallowed. Any infection of your upper respiratory tract can easily spread to the sinuses. The resulting inflammation and pain is called sinusitis. Sinus infections are common and can be a major health problem. People often develop sinusitis after they have a common cold.
If the lining of your sinuses becomes blocked in a cold, the mucus gets thick and sticky. Your sinuses may not drain properly and bacteria can then build up in the mucus. Symptoms of a sinus infection are similar to those of a cold:.
A sinus infection can last from 10 days to as long as 8 weeks. This is called an acute sinus infection. Sometimes a sinus infection can become chronicgetting better and then worse again, off and on for months. Chronic sinusitis is medically defined as sinusitis that occurs more than four times a year. The symptoms of acute and chronic sinusitis are similar. Fever is less likely, except in severe cases.
Try moist heat or steam. You can make a steam inhaler by putting hot water in a bowl and inhaling the steam. To do this:. You can also buy a vaporizerwhich creates steam from heat. If another condition is associated with your chronic sinusitis, get treated for it and stick to your medications or treatment plan. See an allergy doctor to identify and have ongoing treatment for allergies.The outer ear comes in all types of shapes and sizes. This structure helps to give each of us our unique appearance.
The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin.
There are three different parts to the outer ear; the tragus, helix and the lobule. The canal is approximately an inch in length. The skin of the ear canal is very sensitive to pain and pressure. Under the skin the outer one third of the canal is cartilage and inner two thirds is bone. The medical term for the ear drum is the tympanic membrane. The ear drum is a transparent gray membrane. Attached to the center part of the drum is the middle ear bone the malleus. Three of the smallest bones of the body are found in the middle ear; they are called the malleus, the incus and the stapes.
These bones are also known as the hammer, anvil and the stirrup. The medical term for all three bones together is the middle ear ossicles.

Look no further, this Bodytomy article gives you a labeled human ear diagram and also explains the functions of its different components.
The human body is like a big machine, and various processes take place inside it. With the help of the various organs and tissues, it carries out some of the most marvelous tasks, that are no less than a miracle! One such organ is the ear that helps us in the process of hearing and balancing. The sound waves entering the ear get converted into electric impulses for the brain to understand and interpret.
Let us take a look at the human ear structure with the help of a diagram, and understand its functions a little more closely. Would you like to write for us?
Hearing Aid Resource for Consumers
Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk The sound waves travel first through the ear canal and vibrate the eardrum. Before the sound waves enter the inner ear, the total pressure must be amplified.Anatomy - Middle Ear
The ossicles in the middle ear do the job of amplification. Then the cochlea in the inner ear conducts the sound through a fluid. Cochlea is a complex part of the ear, which takes the physical vibrations caused by the sound waves and translates them into electrical information for the brain to recognize as sound.
The organ of corti which contains thousands of tiny hair cells, when moved, sends electrical impulses through the cochlear nerve. The cochlear nerve then passes these impulses to the cerebral cortex and the brain interprets them, and we get to hear. We are sure that the aforementioned information must have added to your knowledge about the human body. Here is a blank human ear diagram for you to label, so that you can memorize the different parts of this vitally necessary organ, for good.
