Hearing System
- What are the structures
that participate in the human
auditory sensitivity?
The structures of sensitivity are the ears (external, midthe human auditory (^) dle
and internal), tnerves and the auditory areas ohe vestibulocochlearf the (^)
brain (located in the temporal lobes of
both hemispheres).
- What are the main parts of
the human ear?
The human ear is dividmains parts: the external ear, theed into three
middle ear and the internal ear.
- What are the structures
that form the external ear?
What is its function?
The internal ear comprises the pinna, or
auricle, and the auditory canal. Itsfunction is to conduct the sound waves (^)
to the tympanum.
- What are the elements that
form the middle ear? What are
the names of the three middle
ear ossicles that participate in
the phonosensitivity?
The middle ear is fotympanum, the ossicular chain rmed by theand the (^)
oval window. The functional ossicles of
the middle ear are the hammer(malleus), the incus and the stapes.
- What is the tympanum? In
which part of the ear is it
located and what is its
function?
The tympanmembrane located in um (or ear drum) is athe middle ear (^)
just after the auditory canal and so it
separates thexternal ear. The function oe middle ear from thf the e
tympanum is to vibrate with the same
frequency of reach it. the sound waves that
- How is the sound vibration
captured by the tympanum
transmitted through the
ossicular chain of the middle
ear?
The acoustic transmission from the
external to internal ear too) the middle ear (and to this entirely mechanical.e (^)
The vibration omembrane triggers the vibration of the tympanic (^) f the
hammer that then causes the incus to
