Physiology of hearing

Hearing starts with the outer ear. When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). ... The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).

What is the physiology of hearing and balance?

The inner ear balance mechanism has two main parts: the three semicircular canals and the vestibule. Together they are called the vestibular labyrinth and are filled with fluid. When the head moves, fluid within the labyrinth moves and stimulates nerve endings that send impulses along the balance nerve to the brain.

What is the anatomy and physiology of the ear?

In summary then, anatomically, the ear consists of a sound conducting mechanism and a sound transducing mechanism. The sound conducting mechanism has two parts, the outer ear consisting of the pinna and ear canal, and the middle ear consisting of the tympanic membrane.

Whats the process of hearing?

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. ... The bones in the middle ear amplify, or increase, the sound vibrations and send them to the cochlea, a snail-shaped structure filled with fluid, in the inner ear.

What is physiology simple?

Physiology is the study of how the human body works. It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together. It helps us understand what happens in a healthy body in everyday life and what goes wrong when someone gets sick.

What do semicircular canals do?

Your semicircular canals are three tiny, fluid-filled tubes in your inner ear that help you keep your balance. When your head moves around, the liquid inside the semicircular canals sloshes around and moves the tiny hairs that line each canal.

What is the receptor for hearing?

The cochlea is filled with two fluids (endolymph and perilymph), inside the cochlea is the sensory receptor — the Organ of Corti — which contains sensory cells with hair-like structures (hair cells) that are the nerve receptors for hearing.

Is the Utricle part of the physiology of hearing?

1) The cochlea is responsible for hearing, 2) the semicircular canals have function associated with balance, and 3) the vestibule which connects the two and contains two more balance and equilibrium related structures, the saccule and utricle.

What is the auditory canal?

external auditory canal, also called external auditory meatus, or external acoustic meatus, passageway that leads from the outside of the head to the tympanic membrane, or eardrum membrane, of each ear. ... The canal is nearly 1 inch (2.5 cm) in length and is lined with skin that extends to cover the tympanic membrane.

What is conductive hearing?

About Conductive Hearing Loss

A conductive hearing loss happens when sounds cannot get through the outer and middle ear. It may be hard to hear soft sounds. Louder sounds may be muffled. Medicine or surgery can often fix this type of hearing loss.

How does hearing work psychology?

The hearing system is designed to assess frequency (pitch) and amplitude (loudness). Sound waves enter the outer ear (the pinna) and are sent to the eardrum via the auditory canal. The resulting vibrations are relayed by the three ossicles, causing the oval window covering the cochlea to vibrate.

How does the brain process sound?

The tiny hair cells in our inner ear send electrical signals to the auditory nerve which is connected to the auditory centre of the brain where the electrical impulses are perceived by the brain as sound. The brain translates the impulses into sounds that we know and understand.

What part of the brain processes sound?

The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching.
