What is the role of stapes bone in internal ear?
605110
The stapes is the oldest of the three ear bones in mammals.  Birds and reptiles only have a stapes (called a columella).  The malleus and incus are both part of the jaw.  The stapes also used to be long and thin instead of stirrup shaped.  This is still true for monotremes, marsupials, and xenarthrans (armadillos, anteaters, and sloths).  The stirrup shape is caused by the passage of an artery through the hole in the middle.\n\nThe role of the stapes is the same in epitherian placentals as it has been in reptiles.  It transmits vibration to the fenestra ovalis in the cochlea.  It's in the cochlea where differential vibration of the various hairs allows for precision of sound interpretation.  \n\nIn mammals the vibration of the stapes is transmitted from the incus.  In nonmammalian vertebrates, these vibrations are transmitted directly from the ear drum.

THe majority if it is in the semicircular canals; a little bit of it is in a small area attached to them.\n\nBalance, however, is sensed by hairlike projections INTO the fluid that does the sensing, as the fluid's intertia causes it to "flow" when the head moves...\n\nThe semicircular canals are close to the cochlea, by the way...

Because antibiotics kill bacteria, and an inner Ear infection is a virus. Check the link below to find out about the difference between the two. Not to be rude because in no way do I want to be but ottis media as described in the response below mine is the middle ear. But some of the drops described may help.

Not sure what you're asking, but, barring injury to one of your ears or to the auditory centers of the brain, the two ears contribute the same thing.\n\nTwo ears helps us determine the direction a sound is coming from.  The brain is acutally able to tell that a sound reaches one ear slightly before the other.

Vibrations in air --> external auditory meatus (duct) lets vibrating air pass --> tympanic membrane vibrates --> hammer (malleus) moves --> anvil (incus) moves --> stirrup (stapes) moves --> oval fenestra (opening into inner ear)--> endolymphatic fluid vibrates --> three parallel ducts that form the cochlea: vibrations travel through vestibular channel --> apex --> tympanic channel (vestibular and tympanic channel surround the cochlear channel or Corti organ) --> membrane of round window vibrates. \nVibrations stimulate different parts of the Organ of Corti --> Auditory nerve (VII cranial nerve pair) --> medulla oblonga at the base of the brain. \n\nConfused?

Cartilage is a bluish white rubbery tissue found in human beings and animals that have backbones.  It cushions bones against shock and prevents them from rubbing against one another.  It also makes an elastic framework for the ear and respiratory passages.  \n\nBone tissue contains three kinds of cells:  osteocytes, osteoblasts, and osteoclasts.  Osteocytes are cells that lie deeply in a mixture of protein fibers and hard bony tissue.  Osteoblasts form this mixture by laying down new fibers and depositing bone.  Osteoclasts break up the mixture where the bone needs to be remodeled during growth.  About 2/3 of the weight of bony tissue is made up of mineral matter, mostly calcium and phosphorus.  The rest is organic matter, mostly collagen, which is a fibrous protein.

muscles provide both support and functionality. Muscles pull ang push on bones so that they may work. Digestive system digests food and provides energy supply and calcium deposits. Circulatory system transports essential nutrients into bones. Nervous system regulates the action of the bones whether to move or not. Endocrine system parathyroid gland regulates bone formation and bone breakdown. Integumentary system protects bone and muscle from outside environment. Respiratory system brings oxygen

Internal skeletons are much better for a larger organism because it gives the body internal strength and integrity and protects all the vital organs incase the flesh can be penetrated. It also gives the body more strength in keeping its own weight up against the forces of gravity. However, for a very small, light organism I believe an exoskeleton is superior since gravity does not pull down on the organism as much.

Otitis externa - commonly known as swimmer's ear - is an infection of the ear canal, the tubular opening that carries sounds from the outside of the body to the eardrum. It can be caused by many different types of bacteria or fungi.\n\nThe infection commonly occurs in children who spend a lot of time in the water. Too much moisture in the ear can irritate and break down the skin in the canal, allowing bacteria or fungi to penetrate. In temperate climates, otitis externa occurs more frequently during the summer months, when swimming is more common.\n\nBut you don't have to swim to get swimmer's ear. Anything that causes a break in the skin of the ear canal can lead to an infection. Dry skin or eczema, scratching the ear canal, vigorous ear cleaning with cotton-tipped applicators, or inserting foreign objects like bobby pins or paper clips into the ear can all increase the risk of developing otitis externa. Sometimes, in a child with a middle ear infection, pus collected in the middle ear can drain into the ear canal through a hole in the eardrum and cause otitis externa to develop.\n\nSigns and Symptoms\n\nThe primary symptom of otitis externa is ear pain, which can be severe and gets worse when the earlobe or other exterior part of the ear is pulled or pressed on. It may also be painful for a person with otitis externa to chew. Sometimes the ear canal itches before the pain begins.\n\nSwelling of the ear canal may make your child complain of a full or uncomfortable feeling in the ear. The outer ear may become reddened or swollen, and lymph nodes around the ear may become enlarged and tender. There may be some discharge from the ear canal as well; it may be clear at first but then turn cloudy, yellowish, and pus-like. Hearing may temporarily be affected if pus and debris or swelling of the canal blocks the passage of sound into the ear. Fever is not common in typical cases of otitis externa.\n\nContagiousness\nOtitis externa is not contagious.\n\nPrevention\nUsing over-the-counter drops of a dilute solution of acetic acid or alcohol in the ears after getting them wet can help prevent otitis externa, especially if your child is prone to the infection. These drops are available at pharmacies and should only be used in children who do not have ear tubes or a hole in the eardrum. After spending time in the water, it is also a good idea for children to gently dry their ears with a towel and help water run out of their ears by turning their heads to the side. Speak with your child's doctor before using earplugs.\n\nTo avoid trauma to the ear, children should not clean their ears themselves and should never put objects into their ears, including cotton-tipped applicators.\n\nIncubation\nThere is no set incubation period for otitis externa, but the ear pain often follows an episode of swimming or immersion in water.\n\nDuration\nOtitis externa is usually cured within 7 to 10 days of starting treatment.\n\nProfessional Treatment\nTreatment of otitis externa depends on the severity of the infection and how much pain the child feels. For milder cases, your child's doctor may prescribe eardrops that contain antibiotics to fight the infection and a steroid to reduce swelling of the ear canal. Eardrops are usually given several times a day for 7 to 10 days.\n\nIf swelling of the ear canal makes it difficult to give the drops, your child's doctor may insert a cotton wick into the canal to help carry the medicine inside the ear. In some cases, the doctor may need to remove pus and debris from the ear with gentle cleaning or suction. This will allow the eardrops to work more effectively. For more severe infections, oral antibiotics may be given as well, and the doctor may order a culture of some of the discharge from the ear to help identify which bacteria or fungi are causing the infection.\n\nOver-the-counter pain relievers can be used to manage any pain your child may feel. Once treatment has begun, your child will st
