Entire ear section (b/w)

Unlabeled graphic:
Simple black and white cross-section of ear. For worksheets, printouts etc.

With the help of this graphic the most important functional areas of the ear and their significance in the hearing process can be explained.

Information and ideas:
The teacher can label the graphic together with the students on the computer screen or get the students to label it themselves either on a printout or at the computer screen.

Sense organ of balance - position

Labeled graphic:
The cupola changes its shape when it is bent and stimulates the sensory hairs. The calcium carbonate crystals act as extra ballast.

The cupola (gelatinous mass) changes its shape when it is bent and stimulates the sensory hairs. The calcium carbonate crystals act as extra ballast. The lymph simply serves to absorb here.

Information and ideas:
This graphic is very useful for showing the function of the sense of position in the inner ear.

Relevant for teaching:
Structure and functions of a sensory organ
Reception of stimuli and processing of information

Middle ear section

Graphic with detailed labeling:
Section view of human ear with the individual parts of the middle ear.

The middle ear is formed by an air-filled cavity lined with mucous membrane and consists mainly of the tympanic cavity and the Eustachian tube.
The tympanic cavity contains the ossicles "malleus?, "incus? and "stapes?.
These are joined together loosely and can move so that, with their help, vibrations from the eardrum can be picked up and transmitted to the inner ear.

Information and ideas:
Can be used in worksheet, worked on together via digital projector, as an overhead transparency.

Unlabeled graphic:
Cross-section of the entire ear, for example, to be incorporated in presentations or for individual projection.

Cross-section of entire ear.

Information and ideas:
This graphic can be used to describe and explain the most important functional areas of the ear and their role in the hearing process.
The teacher can look at the graphic together with the students on the computer screen or get the students to do the labelling either on printouts or on the computer.

Outer ear section

Graphic:
The most important parts of the outer ear with pinna, ear canal, hair follicles, ceruminous glands and eardrum.

The outer ear consists of the pinna and the ear canal. The ear canal ends at the eardrum.
In the membranous wall of the ear canal there are glands which produce cerumen (earwax). At the edge of the ear canal there are some small hairs, hair follicles, which serve as protection against foreign bodies.

Information and ideas:
Helpful to distinguish outer, middle and inner ear.
Can be used, for example in a worksheet, for work together in class with the digital projector, as overhead transparency.

Inflammation of the middle ear

Labeled graphic:
Section of an ear shows the regions affected by middle ear inflammation.

In cases of inflammation of the middle ear (Otitis media) the mucous membrane of the tympanic cavity is inflamed.

Middle ear inflammation is usually caused by infections of the nasopharynx region which rise up into the tympanic cavity via the Eustachian tube.

Information and ideas:
This graphic is good for discussing possible complications (for example "mastoiditis?). The students should be made aware of how important it is to have these diseases properly treated and to make sure that they recover fully and properly.
Further information regarding inflammation of the middle ear in particular and diseases of the ear in general is available as information sheet on the media portal of the Siemens Stiftung.

The Ear, Hearing and Hearing Impairment: Middle ear section - labeling arrows

Unlabeled graphic:
Section view of human ear with the individual parts of the middle ear - with arrows for detailed labeling.

The tympanic cavity contains the ossicles "malleus", "incus" and "stapes".
These are joined together loosely and can move so that, with their help, vibrations from the eardrum can be picked up and transmitted to the inner ear.
