The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bones—the malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.

Beside above, what are the 3 major parts of the ear? The human ear has three main sections, which consist of the outer ear, the middle ear, and the inner ear. Sound waves enter your outer ear and travel through your ear canal to the middle ear.

  • Tympanic membrane (eardrum). The tympanic membrane divides the external ear from the middle ear.
  • Middle ear (tympanic cavity), consisting of: Ossicles.
  • Inner ear, consisting of: Cochlea.

How many bones are in your ear?

Ossicles. The middle ear contains three tiny bones known as the ossicles: malleus, incus, and stapes.

Which is the smallest bone in human body?

The stapes is the third bone of the three ossicles in the middle ear. The stapes is a stirrup-shaped bone, and the smallest in the human body. It rests on the oval window, to which it is connected by an annular ligament.

How does hearing occur in the human body?

Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear. The inner ear is shaped like a snail and is also called the cochlea. The brain tells you that you are hearing a sound and what that sound is.

How do ears work simple?

Here is how the ear works normally:
