Senses/ Anatomy Of Ear And Eye.

Front 1

Ossicles

Back 1

Malleus, Incus, Stapes. Their function is to transfer sound from the outer ear to the inner ear.

Front 2

What is the required amount of Decibels needed in order to damaged the Stereocilia?

Back 2

80 dB

Front 3

Myopia (near sightedness)

Back 3

-Having difficulty seeing objects that are farther away from your eyes.

-Caused by Ciliary muscles that are too strong or an eyeball that is too long.

Front 4

If a person were to have trouble seeing near objects, what eye condition would they have?

Back 4

Hyperopia (far sightedness)

Front 5

Astigmatism

Back 5

Altered shape of the cornea, alters focus of light

Front 6

In the brain, which hemisphere is responsible for interpreting the left visual field?

Back 6

The Right Hemisphere

Front 7

Cornea

Back 7

Lets light into the eye

Front 8

Choroid

Back 8

supplies all of the layers in the eye with blood.

Front 9

Lens

Back 9

focus's light received from Cornea and projects it onto the retina

Front 10

Retina

Back 10

loaded with photo-receptors and convert light energy into electrical signals that the brain recieves

Front 11

Cones

Back 11

detect fine detail and color

Front 12

Rods

Back 12

control the peripheral vision and may only detect white and grey colors

Front 13

Frequency

Back 13

-The number of waves that pass a certain point in a given time frame

-High pitched noises are the result of a shorter wave length

-Low pitched noises are the result of a longer wavelength

Front 14

Amplitude

Back 14

-The difference between the high and low pressures created in the air by that sound wave

Front 15

External Ear

Middle Ear

Inner Ear

Back 15

External and Middle Ear are only involved with hearing, while the Inner Ear is key to both hearing and maintaining your equilibrium

Front 16

Middle Ear (Tympanic Cavity)

Back 16

Amplifies sound waves so they are stronger when they enter the inner ear and that the sounds waves are strong enough to move the fluid in the Inner Ear.

Front 17

Auricle

Back 17

To enhance and collect sound vibrations and to pass them along deeper into the ear

Front 18

External Auditory Canal

Back 18

amplifies and carries sound to the tympanic membrane, use hair and earwax for protection

Front 19

Tympanic Membrane (eardrum)

Back 19

Round, elastic structure that vibrates with sound waves and is connected to the Ossicles (Maleus, Incus and Stapes)

Front 20

Ossicles

Back 20

amplifies and transfers sounds from outer ear to the inner ear (from Tympanic Membrane to the Oval Window) Stapes causes Oval Window to vibrate.

Front 21

Oval Window

Back 21

beginning of inner ear and takes amplified vibrations and transfers them to the fluid filled Cochlea (organ of sound)

Front 22

Eustachian Tube

Back 22

Connects middle ear to the throat and allows pressure equalization in the middle ear with the outer ear.

Front 23

Cochlea

Back 23

used for hearing as well as converting mechanical energy (vibrations) into electrochemical impulses. The Cochlea contains the organ of hearing= the organ of Corti (stereocilia)

Front 24

Round Window

Back 24

membrane covered opening at the end of the Cochlea, finishes a sound wave

Front 25

Vestibule

Back 25

responsible for static or gravitational equilibrium and is comprised of the fluid filled utricle and saccule.

Front 26

Semicircular Canals

Back 26

arranged in three different planes (X,Y,Z) and is responsible for rotational or dynamic balance

Front 27

Vestibular Branch

Back 27

responsible for static and rotational equilibrium

Front 28

Cochlear Branch

Back 28

responsible for sound and hearing

Front 29

Pathway of sound through the Ear (in order)

Back 29
