(13 cards)
Where are the receptor cells to hear
What are the 3 major parts of the ear?
in our ears
- Outer Ear
- Middle Ear
- Inner Ear
What is an eardrum?
Why is it give this name?
A membrane of the ear AKA tympanic membrane
As sound is going through the ear, it has a tendency to vibrate
Where is the inner ear located?
What are the 2 parts of the inner ear?
in the skull
cochlea
3 semi-circular canals for balance
What 2 parts make up the outer parts of the ear?
The pinna (outer ear that we see) is made of
Pinna
Auditory canal
elastic Cartlidge
its bendable
What doe the middle ear consist of?
What do these ossicles do?
3 little bones (ossicles)
Malleus
Incus
Stapes
Pick up the vibrations of the ear drum and pass them into the inner ear.
Amplify the sound
What part of the inner ear, contains the receptor cells for hearing?
cochlea
Sound is a form of
What is the pathway for sound?
mechanical energy (picked up in vibrations)
Pinna Outer ear
Eardrum
Bones
Cochlea
The bigger the pinna,
Steps for Middle Ear sound from the tympanic membrane
What passes the vibration to the inner ear
the more sound will be gathered
the vibrations go into the malleus
vibrations go into the incus
vibrations go to the stapes
Oval Window
Outer Ear:
Middle Ear:
Inner Ear:
Gathers sound and directs it to the ear drum
Transforms sound energy for inner to receive as a signal
Location of auditory receptors (cochlea) and fluid filled
tubes for balance (semicircular canals)
Cells in the cochlea
What does the liquid in the cochlea do?
The hair cells are
Supporting cells
Hair Cells (elongated with cilia)
Liquid vibrates, pressure waves passes the vibrations to the hair cells and stimulate, and bend them
nerve endings and connecting to the auditory nerve (to the brain
The _________ ___________ and __________ ________ in the
inner ear function in ____________and equilibrium
The
semicircular canals, arranged in three spatial planes, detect ______________________________________________. The utricle and saccule
tell the brain ________________and inform it of the body’s position or________________________.
utricle, saccule, semicircular canals
balance
angular movements of the head
which way is up
linear acceleration
Sever ear infections
can affect your balance
