Is the ear canal the same as the eardrum?
No, the ear canal and the eardrum are different structures in the ear. The ear canal is a tube that carries sound to the eardrum, a thin layer of tissue that vibrates in response to sound waves. The eardrum separates the outer ear from the middle ear.
How deep is the ear canal?
The outer ear flap 'pinnae' surrounds each hole in the side of the skull and leads into the ear canal. This irregular cylinder averaging 6mm diameter and approx 25mm long narrows slightly, then widens towards its inner end, which is sealed off by the ear-drum.
Does the ear canal end at a tightly stretched membrain called the cochlea?
The ear canal actually ends at the eardrum. This is the tightly stretched membrane, also known as the "tympanic membrane". The cochlea is located in the inner ear and is a cavity filled with fluid.
Trace the path of sound waves as they enter the ear Start with the outer ear?
Sound waves enter through the outer ear, then sound waves move through the ear canal. Next sound waves strike the eardrum, causing it to vibrate, then vibrations enter the middle ear. Then the hammer picks up the vibrations, then vibrations are passed to the anvil. Next the vibrations are transmitted to the stirrup, then a vibrating membrane transmits vibrations to the inner ear, and then vibrations are channeled into the cochlea. Then nerve cells detect vibrations and convert them to electrical impulses, then electrical impulses are transmitted to the brain. Then the brain interprets electrical impulses as sound.
What are the names definitions and functions of the parts of the ear?
Outer earIt consists of Pinna, ear canal and ear drum. Pinna (also called auricle): It is outer most (and visible) portion of ear. Its external parts are wide while inner portion is narrow. Because of its shape it act as a funnel (collects the sound and directs it through ear canal to ear drum).Ear canal (auditory canal): It contains sebaceous glands which secrete ear wax (cerumen) for lubrication of ear.Ear drum (tympanic membrane): It is thin membrane located at the end of outer ear. It carries the sound towards middle ear.Middle earIt consists of three ear bones or ossicles (malleus, incus and stapes). These ossicles transmit sound to the inner ear. Malleus (also called hammer): It is hammer like ossicle. Its one end is attached to ear drum while other is connected with incus.Incus (anvil): It is anvil shaped bone, attached with malleus and stapes.Stapes: stirrup shaped bone attached to incus and oval window or vestibular window (membrane covered opening between middle ear and inner ear).Inner earIt contains cochlea, vestibule and semicircular canals. Cochlea: It is coiled portion and auditory portion of inner ear.Semi-circular canal: Three fluid filled canals horizontal semi-circular canal, posterior semi-circular canal and anterior semi-circular canal are called semi-circular canals.The fluid inside these canals is called endolymph. The dilation at one end of canal is called ampulla. Ampulla contains Cupula and hair cells.Semi-circular canals are responsible for body balance and detect direction of rotation of head.Vestibule: It is located between the semi-circular canals and cochlea. Its anterior and inferior part has several minute holes for the passage of filaments of acoustic nerve (auditory nerve) to saccule. Saccule detects the motion of head when it moves vertically. At the upper and back of vestibule a structure called utricle detects the degree of tilt movement of head.
What is the end of the ear canal called?
im sure its ear drum
Is the ear canal the same as the eardrum?

Is the ear canal a bone?
No, the ear canal is not a bone. It is a tube-like structure made of skin and cartilage that connects the outer ear to the middle ear. The ear canal helps to capture and direct sound waves to the eardrum.
What is the word for definition 'inner end of the auditory canal?
I believe the answer is the ear drum.
What are two parts of the body that are made up of cartilage?
end of your nose and the top of your ear.
What is the outer ear and end of nose made of?
They are made up of cartilage.
Where does the External ear end?
The external ear ends at the ear canal, also known as the external acoustic meatus, which extends from the outer ear to the eardrum.

What are two parts of your body that are made of cartilag?
end of your nose and the top of your ear.
What Two parts of your body's that are made out of Cartilage?
end of your nose and the top of your ear.
Which part of your ear do sound waves enter through?
Sound waves enter the ear through the outer ear, specifically through the ear canal. This canal funnels the sound waves towards the eardrum, which is located at the end of the canal in the middle ear.
Where does the bug go when it flies up your nose?
When a bug flies up a person's nose, usually it will come right back out. Assuming it really gets lodged in there, the bug will end up in the person's sinus cavity. If such an event occurs and the bug does not come out, it may be best to seek medical treatment.
