The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.

Which part of human ear is concerned with?
here are three components to the ear: the outer ear, the middle earand the inner ear. All three are involved in hearing but only the inner ear is responsible for balance. The outer ear is composed of the pinna, or ear lobe, and the external auditory canal.
Where is the cochlea located?
While the cochlea is technically a bone it plays a vital role in the function of hearing rather than simply being another component of the skeletal system. It is located within the inner ear and is often described as hollow and snail- or spiral-shaped.
Which part of human ear is not concerned with hearing?
Vestibular apparatus also known as - the balancing system is the part of the human ear which plays no role in the hearing. These organs provide the necessary sensory information about equilibrium - motion and geeral spatial orientation.
What are the parts of the hearing 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. The middle ear air space is connected to the nose by the Eustachian tube and to the mastoid air cells housing the ossicular chain, the malleus, stapes and incus.
What are the outer parts of the ear?
The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3].
Is the cochlea part of the middle ear?
The ear is composed of three parts: the outer ear and the middle ear transfer sound waves to the inner ear, or cochlea, which transforms the stimulus into a neural signal.
What are the 3 cochlear ducts?
The cochlea is made up of three canals wrapped around a bony axis, the modiolus. These canals are: the scala tympani (3), the scala vestibuli (2) and the scala media (or cochlear duct) (1).
How sounds are detected in cochlea?
Hair cells—sensory cells sitting on top of the basilar membrane—ride the wave. Hair cells near the wide end of the snail-shaped cochlea detect higher-pitched sounds, such as an infant crying. Those closer to the center detect lower-pitched sounds, such as a large dog barking.
Which part of the human ear plays no role in the hearing as such but is otherwise very much required?
Vestibular apparatus is a part of inner ear which has no role in hearing but responsible for the maintenance of balance of the body and posture.
What are the 3 major parts of the ear?
The ear is made up of three different sections that work together to collect sounds and send them to the brain: the outer ear, the middle ear, and the inner ear.
What is top part of ear called?
The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory canal, a short tube that ends at the eardrum (tympanic membrane).
Can you hear without the outer ear?
Yes, but with more difficulty. The outer part of your ear, known as the pinna, funnels sound into your ear canal, like a megaphone in reverse. If someone cut it off, everything would sound quieter.
