Toolbox/Middle Ear Anatomy

_

This is an example interactive diagram created using the Wikidiagrams library. One aim of the project is to provide interactive diagrams that explain everything to do with Audacity. The code is also expected to be useful for other code projects, and eventually for Wikipedia too, for biochemical pathways and other interactive diagrams.

This is the spec for the interactive diagram which shows the structure of the Middle Ear:

DISPLAY_FOCUS_DETAIL Focus=SmallCircle
  BUTTON_ROW
  IMAGE_WITH_HOTSPOTS

The specification above builds a simple focus-detail display. There's an interactive demo.

This is one of three related pages. The other two are:

The detailed data for the regions, buttons and tooltips follows.

BUTTON:LABEL=Ear;TIP=

The Ear

Sound is transformed from pressure waves in air to vibrations of tiny bones, to movement in cells that generate electrical impulses in the auditory nerve.

BUTTON:LABEL=Middle;TIP=

Middle Ear

The middle ear has tiny bones that transmit pressure from the outer ear to the inner ear.

BUTTON:LABEL=Inner;TIP=

Inner Ear

The cochlear of the inner ear is a spiral shaped organ that has nerve cells that respond to different frequencies of sound.

Middle Ear

The middle ear has tiny bones that transmit pressure from the outer ear to the inner ear.

Auditory Ossicles

The ossicles are tiny bones that transmit sound from the tympanic membrane to the oval window.

NEXTZONE:TIP=

Oval Window

The oval window is a membrane that transmits vibrations in the ossicles to the fluid in the inner ear. It is oval rather than round, so that it transmits all relevant frequencies. Were it round, there would be characteristic frequencies that it absorbed more than others.

NEXTZONE:TIP=

Round Window

The round window helps in equalising the pressure of the fluid in the inner ear. It moves outwards as the oval window is pushed in, and vice versa.

NEXTZONE:TIP=

Auditory Tube

The Auditory tube equalises pressure between the inside and outside of the ear. This is related to the sensation of 'ears popping' when flying.


NEXTZONE:TIP=

Tympanic Cavity

The Tympanic Cavity is an air filled region of the inner ear

NEXTZONE:TIP=

Tympanic Membrane

The Tympanic membrane or ear drum converts vibrations of sound in air to vibrations of the ossicles

NEXTZONE:TIP=

External Acoustic Meatus

The ear canal brings sound to the middle ear. The inner structures of the ear are housed in a bony compartment, whereas the outer ear is outside the skull and uses cartilage to hold its shape.

NEXTZONE:TIP=

Ligaments

These stabilize the ossicles. Muscles can tighten and slacken these ligaments so as to make this system for transmitting sound more or less sensitive.
