anatomy 8

three layers of the eye

fibrous, vascular, sensory

vascular layer of the eye

sensory layer of the eye

function of the fibrous layer of the eye

Protects they eyeball and maintains it's shape

function of the sensory layer of the eye

Contains the nerve cells that process visual information and sends it to the brain.

rods?

cones?

What does vitamin A deficiency cause?

visual acuity?

the ability to see fine detail(acuity=sharpness)

function of the lens

lacrimal gland

How does the light travel for resting eye?

resting eye is set for

How does light travel through eye?

three parts of the ear?

external part of the ear?

auricle (pinna)

middle ear?

function of the middle ear?

internal (inner) ear?

function of the internal ear?

ceruminous glands and what do they produce?

external acoustic meatus?

three auditory ossicles?

function of auditory ossicles?

malleus?

incus?

stapes?

otosclerosis?

chemoreceptors?

ocations of taste buds on the tongue?

five taste sensations?

What taste cells regenerate?

aqueous humor?

vitreous humor?

optic discs?

binocular vision?

photopupillary reflex?

What areas of the brain are responsible for specific senses?

Vision- occipital lobe

equilibrium- the cerebellum

conduction deafness?

two types of equilibria?

static equilibrium?

dynamic equilibrium?

relationship between the middle ear and the nasopharynx?

the lens

main function is to refract light, the transparent structure behind the pupil that changes shape to help focus images on the retina

inner ear parts

the innermost part of the ear, containing:
1. cochlea
2. semicircular canals,
3. vestibular sacs

fibrous layer of eye

sclera and cornea anteriorly

choroid, ciliary body, iris

layer of the retina and is retinal pigment epithelium layer

function of vascular layer of the eye

Supplies oxygen and nutrition for the eye

two photoreceptors

rods and cones

(night vision) retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond

(color vision) provide vision in bright light, color vision, sharp images

night blindness

fovea centralis?

area of the retina with only cones

ocuses light on the retina.

a small, almond shaped gland located in the supralateral part of the orbit that secrets tears

in parellel rayes

distance vision

through the cornea and through a lens, which focuses light on the Fovea Centralis

external, middle, inner

function of the external ear?

collects and directs sound waves to the tympanic membrane

the small cavity behind the tympanic membrane that contains 3 bones (the malleus, the incus, and the stapes).

transmit sound waves to the inner ear

A bony labyrinth located within the temporal bone, where we find sensory structures associated with equilibrium and hearing

hearing and equilibrium

modified apocrine sweat glands (ear wax)

auditory canal, narrow champer carved into the te,portal of skull, Ear Canal

malleus (hammer), incus (anvil), stapes (stirrup)

transmit vibrations from tympanic membrane to inner ear via the oval window. the oval, round windows connect middle to inner ear.

"hammer" first of 3 ossicles (bones) of the middle ear

"anvil" middle ossicle of middle ear

"stirrup," most inner of the 3 ossicles of the middle ear

Overgrowth of spongy bone in the middle ear that doesn't allow the bones of the middle ear to vibrate

A receptor that responds to a change in the chemical composition (PaCo2 and pH) of the fluid around it.

anterior 2/3, posterior glossopharyngeal 1/3 and Pharynx ( review notes)

sweet, sour, salty, bitter, umami (savory) (page 300)

gustatory taste cells (review page 300)

the clear fluid filling the space in the front of the eyeball between the lens and the cornea. (page 282)(Eye Pressure)
