what is your blind spot

where the optic nerve exits aka your optic disc

100

Where are rods and cones located in the eye (general location)

back of the retina

100

Our sense of hearing is dependent on what

displacement of fluid called endolymph and hair cells that detect movement

100

The primary structures of motion and balance are...

Semicircular canals/ampulla, utricle, saccule

100

ATP is produced here

mitochondria

200

what does your lateral rectus muscle do?

abduction of the eye

200

The type of vision that rods help with

night vision, peripheral vision, or high sensitivity vision

200

Where do endolymph displacements occur in the ear?

cochlea

200

What causes acceleration/deceleration & currents of the fluid in the semicircular canals?

endolymph and bone of skull move at different rates

200

This covers your brain and spinal cord to prevent infection

meninges

300

function of ciliary muscles

modify lens shape and help focus inverted image on the retina

300

what cells in the eye send action potentials to the brain?

ganglion cells

300

Type of cartilage that makes up the outer ear

elastic hyaline

300

What nerve are action potentials sent to regarding balance?

vestibulocochlear nerve

300

A slit like opening in a bone is called...

a fissure

400

This is where sound is directed to in the ear

tympanic membrane

400

what does cyclic GMP do when it is dark?

depolarizes rod/cone membrane

400

When someone has an ear infection, this is obstructed causing pressure changes

Eustachian tube

400

When do action potentials stop in the semicircular canals?

when acceleration/deceleration of fluid and body stops

400

yellowing of the skin is what condition?

Jaundice

500

is the auricle a part of the outer, middle, or inner ear?

outer

500

This disease causes increased occular pressure and damages the optical nerve

Glaucoma

500

infrasonic means...

low frequency, vibrations in the body

500

The utricle and saccule detect...

whether changes in position are maintained in a stationary matter for longer periods of time

500

Deepest layer of the epithelium is...

Stratum Basale
