Outer Ear : The structure of the outer ear in the human body


What is Outer Ear?

The outer ear is the part of the ear you can see. Outer ear consists of the pinna (also called the auricle) and the ear canal. The pinna is made of cartilage and skin. The ear canal is a passageway that starts at the opening of the pinna and ends at the eardrum, which separates the outer ear from the middle ear.

Most people are familiar with the outer ear. The part of the ear that is visible and protrudes from the side of the head is the pinna, which funnels sound waves into the ear canal. The canal is a short, curved tube that leads to the eardrum, which separates the outer and middle ear.

The structure of the outer ear in the human body

The outer ear is the visible part of the ear, which consists of the earlobe and the auricle. The function of the outer ear is to collect sound waves and direct them to the eardrum. The auricle is made up of cartilage and is attached to the side of the head. The earlobe is made up of flesh and is attached to the side of the head..

The structure of the outer ear in the human body is very important for hearing. The outer ear is made up of three parts: the pinna, the external auditory canal, and the tympanic membrane. The pinna is the visible part of the ear that protrudes from the head. The external auditory canal is the portion of the ear that connects the pinna to the tympanic membrane.

The internal ear is encased in the temporal bone​ and consists of three parts:

  • Vestibule : the central internal ear cavity

  • Cochlea : the organ of listening to

  • Semicircular Canals ​: a part of the stability machine

The intrinsic muscle tissues of the outside ear are:

  • The helicis main is a slim vertical band located upon the anterior margin of the helix. It arises under, from the spina helicis, and is inserted into the anterior border of the helix, simply wherein it's miles approximately to curve backward.

  • The helicis minor is an indirect fasciculus, covering the crus helicis.

  • The tragicus is a quick, flattened vertical band on the lateral surface of the tragus. Also referred to as the mini lobe.

  • The antitragus arises from the outer part of the antitragus, and is inserted into the cauda helicis and antihelix.

  • The transverse muscle is placed at the cranial surface of the pinna. It consists of scattered fibers, partly tendinous and in part muscular, extending from the eminentia conchae to the prominence corresponding with the scapha.

  • The indirect muscle additionally at the cranial floor, consists of some fibers extending from the higher and returned a part of the concha to the convexity right away above it.

The auricular muscular tissues (or extrinsic muscular tissues) are the 3 muscle mass surrounding the auricula or outer ear:

  • anterior auricular muscle

  • advanced auricular muscle

  • posterior auricular muscle

What is the role of the outer ear in the human body?

  1. The outer ear consists of the pinna and the ear canal. The primary function of the outer ear is to collect sound waves and direct them to the ear canal. The outer ear also helps to protect the ear canal from foreign bodies and excessive noise.

  2. The outer ear, which includes the pinna as well as the ear canal, plays an important role in the human body. The pinna is the visible part of the ear that protrudes from the head. The ear canal is the passageway that leads from the outer ear to the eardrum. The primary function of the outer ear is to funnel sound waves from the environment into the ear canal.

  3. The outer ear is the visible part of the ear that extends from the side of the head. The outer ear includes the ear canal, which leads to the eardrum. The outer ear funnels sound waves into the ear canal, which amplifies the sound and directs it to the eardrum. The eardrum vibrates when it is struck by sound waves, and these vibrations are transmitted to the inner ear.

  4. One consequence of the configuration of the outer ear is selectively to reinforce the sound pressure 30- to one hundred-fold for frequencies around three kHz. This amplification makes humans most touchy to frequencies on this range—and additionally explains why they're mainly liable to acoustical damage and listening to loss close to this frequency. Most human speech sounds are also disbursed in the bandwidth round three kHz.

Ear symptoms in the human body

Ear symptoms in the human body can be extremely uncomfortable. Many times, people will experience an earache, which is a sharp pain in or around the ear. Other common ear symptoms include a feeling of fullness in the ear, tinnitus (ringing in the ears), and vertigo (a spinning sensation). While ear symptoms can be extremely uncomfortable, they are usually not serious and can be treated with home remedies or over-the-counter medications.

Ear symptoms are common. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), over 10 million American adults report some degree of hearing loss. In addition, over 34 million adults suffer from tinnitus, a condition characterized by ringing or roaring in the ears.

  2. Your eustachian tubes join your middle ears to your throat. When you yawn, sneeze or swallow, your eustachian tubes open to equalize the pressure inside of your ears. If those tubes emerge as clogged, it’s known as eustachian tube disorder. Symptoms include tinnitus, muffled listening to, sensation of fullness and possible ear ache.

  3. Swimmer’s ear is an ear canal infection resulting from microorganism or fungi. Getting water to your ear can motivate this circumstance. Swimmer’s ear also can occur in case you get hair spray or different irritants inner of your ear canal. Additionally, it’s not unusual for humans to injure their ear canal with cotton swabs. (Note: When ear cleansing, you need to by no means place cotton swabs inside of your ear canal.)

  4. If you get a hollow for your tympanic membrane, it’s known as a ruptured eardrum. (Your eardrum separates your outer ear from your middle ear.) Infection, trauma, loud sounds or overseas items to your ears can motivate a ruptured eardrum. In maximum cases, a ruptured eardrum will heal on its own in a few weeks. But once in a while, it calls for surgical restore, including tympanoplasty.

  5. Otosclerosis is while ordinary bone reworking occurs to your middle ear. Bone transforming is a regular lifelong process wherein current bone tissue replaces itself with new bone tissue. When this method doesn’t cross as anticipated, but, it can cause health problems. With otosclerosis, the tiny bones inside of your center ear (the malleus, incus and stapes) turn out to be hardened and forestall vibrating. As a result, the sound doesn’t travel properly. Surgery is typically necessary to treat otosclerosis.

  6. Perichondritis happens when the pores and skin of your outer ear turns infected. This circumstance is usually the end result of injury or trauma, inclusive of piercings, contact sports or ear surgical treatment. Antibiotics are important to deal with perichondritis. In uncommon cases, you could need surgical operation to empty any pus from the region.

Middle Ear Transplantation 

Middle Ear Transplantation 

A middle ear implant is a small device that is inserted into the center ear and connected to the components of the ossicle or oval window with the intention to improve hearing. Unlike different hearing aids, a middle ear implant does not now require a speaker. Simply put, the center ear implants paintings by means of transmitting sounds to the internal ear through a small microphone worn in the back of the ear. These sounds are converted into vibrations which are sent to the implant inside the center ear.
