Parts of an Ear
Definitions
The ear collects sounds (as vibrations),
processes them and sends the sound
signals to the brain. The ear also
provides balance and stability to the
human body. The ear is comprised of
three sections: the outer ear, middle
ear, and inner ear.
The pinna, or auricle, is the visible
portion of the outer ear on the
side of the head. The word “ear”
is commonly used to describe
only the external part of the ear,
namely the pinna.
The auditory canal, part of the
outer ear, channels sound from
the outside ear to the eardrum.
The canal also produces earwax,
or cerumen, which lubricates and
protects the canal.
The final part of the outer ear is the
eardrum, or tympanic membrane,
a thin layer of tissue separating the
outer and inner parts of the ear. The
eardrum receives sound waves and
transmits them to the middle ear.
The malleus, or hammer (malleus
is Latin for “hammer”), is the first
bone of the middle ear. Sounds
received by the eardrum causes
it to vibrate, which causes the
malleus to move.
The incus, or anvil (incus is Latin
for “anvil”), is the second bone
of the middle ear, in between
the malleus and stapes. The incus
transmits sound vibrations from
the malleus to the stapes.
The stapes, or stirrup (stapes is Latin
for “stirrup”), is the third bone of the
middle ear. The stapes transmits
sound vibrations from the incus to
the inner ear. The stapes is also the
smallest bone in the human body.
The cochlea, Latin for “snail”, is
a long tube within the inner ear
that is coiled like a snail shell. The
cochlea contains the sensory organ
for hearing, and converts sound
vibrations to electrical impulses.
The cochlear nerve is attached
to the cochlea within the inner
ear. The nerve sends electrical
impulses, created by the
cochlea, to the brain to interpret
as sounds.
The semicircular canals are
a series of loop-shaped tubes
within the inner ear. The fluidfilled canals are instrumental in
maintaining the body’s sense of
balance.
Just as the cochlear nerve receives
hearing information from the
cochlea, the vestibular nerve
receives balance information from
the semicircular canals, and sends
this information to the brain.
The Eustachian tube is a tube
connecting the middle ear and the
pharynx in the throat. Named after
a 16th century scientist, the tube lets
in small amounts of air to equalize
pressure between the middle ear and
the atmosphere outside the body.
Instructions: Print on cardstock and laminate. Cut cards apart. Primary (age 3-6) can use one picture, one label, and a control card to match the names
of the parts correctly. Elementary (age 6-12) can use one picture, one label, and the definition cards to match together, using the control cards when
finished to check their work. There are many books available that show pictures of human ears, and teacher stores often have models of the human ear
so that children can see an ear in person.
