What is the visual part of the ear?
The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane. via
What is examined with the otoscope?
An otoscope is a tool which shines a beam of light to help visualize and examine the condition of the ear canal and eardrum. Examining the ear can reveal the cause of symptoms such as an earache, the ear feeling full, or hearing loss. via
Which medical term describes a type of vision?

What is the correct path of sound through the ear to the brain?
The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses. The auditory nerve sends these impulses to the brain. via
Where does ear canal lead to?
The ear canal, also called the external acoustic meatus, is a passage comprised of bone and skin leading to the eardrum. The ear is comprised of the ear canal (also known as the outer ear), the middle ear, and the inner ear. via
Can doctors see into your middle ear?
First, your doctor will examine the outside of your ear. Then they'll use something called an otoscope to look inside. It's a handheld tool with a light and a magnifying lens that lets your doctor see into your ear canal and get a view of your eardrum. via
Can an otoscope see the inner ear?
A light beam shines through the otoscope into the ear canal. The provider will carefully move the scope in different directions to see the inside of the ear and eardrum. Sometimes, this view may be blocked by earwax. An ear specialist may use a binocular microscope to get a magnified look at the ear. via
Can you see fluid in ear with otoscope?

Who uses an otoscope?
An otoscope or auriscope is a medical device which is used to look into the ears. Health care providers use otoscopes to screen for illness during regular check-ups and also to investigate ear symptoms. An otoscope potentially gives a view of the ear canal and tympanic membrane or eardrum. via
Which is the correct order for sound traveling to the inner ear?
The vibrations are transmitted further into the ear via three bones (ossicles): malleus (hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from the tympanic membrane to the oval window. 5. Once sound passes through the oval window, it enters into the cochlea in the inner ear. via

What is the incus function?
The central of three small bones in the middle ear
The incus, also known as the “anvil,” is the middle of three small bones in the middle ear. The incus transmits vibrations from the malleus to the stapes. The vibrations then move to the inner ear. Conditions that affect the incus often affect the other ossicle bones. via
How far back does your ear canal go?
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the pinna to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter. via
Does the ear canal lead to the brain?

Your doctor may ask you to breathe deeply and swallow to see how the ear drum responds. Your doctor may also measure the pressure inside your ear using specialized tools. via
Can a doctor see fluid in your ear?
An instrument called a pneumatic otoscope is often the only specialized tool a doctor needs to diagnose an ear infection. This instrument enables the doctor to look in the ear and judge whether there is fluid behind the eardrum. With the pneumatic otoscope, the doctor gently puffs air against the eardrum. via
Can your finger reach your eardrum?
Inserting any kind of object, such as a cotton swab, fingernail, or pen, too far into the ear can harm your eardrum as well. Acoustic trauma, or damage to the ear from extremely loud noises, can rupture your eardrum. However, these cases are not as common. via
