What does the middle ear cavity mean?

What does the middle ear cavity mean?

Also known as the tympanic cavity, the middle ear is an air-filled, membrane-lined space located between the ear canal and the Eustachian tube, cochlea, and auditory nerve. The eardrum separates this space from the ear canal. The area is pressurized.

What structures are found in the middle ear cavity?

The middle ear consists of three bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes), the oval window, the round window and the Eustachian tube.

What is middle ear pathology?

BACKGROUND: Middle ear pathology, either otitis media with effusion or tubal dysfunction, is frequently seen in day-care centre children. Recognition and early treatment of this condition is crucial to the prevention of chronic otitis media, which is a major cause of hearing loss in later life.

What is main function of middle ear?

The primary function of the middle ear is to offset the decrease in acoustic energy that would occur if the low impedance ear canal air directly contacted the high-impedance cochlear fluid.

What is the ear cavity called?

Tympanic cavity
The tympanic cavity is a small cavity surrounding the bones of the middle ear. Within it sit the ossicles, three small bones that transmit vibrations used in the detection of sound. The cochlea and vestibule, viewed from above.

What are 2 Functions of the middle ear?

It is classical to ascribe three functions to the middle ear: the transmission of acoustic vibrations from the tympanic membrane to the cochlea, impedance matching between the air in the external auditary meatus and the labyrinthine fluids, and protection of the inner ear by means of the acoustic reflex.

What are the tests for ear problems?

Types of Hearing Tests

  • Pure Tone Testing.
  • Bone Conduction Testing.
  • Speech Testing.
  • Tympanometry.
  • Acoustic Reflex Testing.
  • Auditory Brainstem Response (ABR)
  • Otoacoustic Emissions (OAEs)

What are the three main functions of the ear?

The major task function of the ear is of course to detect, transmit and transduce sound….The ear consists of many small ear parts, but can be divided into three major parts of the ear:

  • The outer ear.
  • The middle ear.
  • The inner ear.
