1

the anterior area of the globe between the lens and the cornea that is filled with aqueous humor

anterior chamber

2

the clear, watery fluid in the anterior chamber of the globe

aqueous humor

3

the large outside portion of the ear through which sound waves enter the ear; also called the pinna

auricle

4

a small elevation in each ear canal

crista

5

a cap of gelatinous tissue in the ear that is involved in the sensation of balance and movement

cupula

6

fluid in the membranous labyrinth of the ear

endolymph

7

one of three anatomic parts of the ear, it contains the pinna, the ear canal, and the exterior portion of the tympanic membrane

external ear

8

the sense of taste

gustation

9

any of several conditions that result in excess sensitivity, especially to touch or to cold

hyperesthesia

10

one of three anatomic parts of the ear, it consists of the cochlea and semicircular canals

inner ear

11

the colored part of the eye

iris

12

a transparent body within the globe that focuses light rays

lens

13

specialized patches of tissue within the utricle and saccule that aide in the sensation of motion

macula

14

one of three anatomic parts of the ear, it consists of the inner portion of the tympanic membrane and the ossicles

middle ear

15

a bulbous protrusion of the olfactory lobe through which scent impulses travel to the olfactory tract

olfactory bulb

16

the area in the brain that receives scent impulses and perceives them as smell

olfactory cortex

17

the passageway for scent impulses to travel from the olfactory bulb to the olfactory cortex

olfactory tract

18

the opening in the bony orbit where the eyeball is located, through which the optic nerve passes to the eyeball

optic foramen

19

either of the second cranial nerves that enter the eyeball posteriorly, through the optic foramen

optic nerve

20

a structure located in the cochlea that contains hairs that are simulated by vibrations to form nerve impulses that travel to the brain and are perceived as sound

organ of corti

21

the three small bones i the inner ear that transmit vibtrations to the cochlear duct at the oval window

ossicles

22

the circular opening in the center of the eye, through which light passes to the lens

pupil

23

a delicate, 10 layered structure of nervous tissue located in the rear of the interior of the lobe that receives light and generates nerve signals that are transmitted to the brain through the optic nerve

retina

24

the white of the eye

sclera

25

a thin membrane that separates the middle ear from the inner ear and sets up vibrations in the ossicles, also called the ear drum

tympanic membrane

26

the area in the brain where signals from the optic nerve are converted into visual images

visual cortex

27

a jelly like substance found in the posterior compartment of the eye between the lens and the retina

vitreous humor
