Question 5

Visceral Pain

Answer 5

pain in body organs

Question 6

The Special Senses

Answer 6

Taste
Smell
Vision
Hearing
Balance

Question 7

the eye

Answer 7

The eyes refract
(bend) and focus the incoming light waves onto the sensitive
photoreceptors (rods and cones) at the back of each
eye

Question 8

the ear

Answer 8

the ear consists of the three principal regions: the outer ear, the middle ear, and the inner ear

Question 9

Outer ear

Answer 9

The outer ear consists
of the auricle and the external auditory canal

Question 10

The middle
ear

Answer 10

The middle
ear contains the auditory ossicles (malleus, incus, and stapes).

Question 11

The inner ear

Answer 11

The inner ear contains the spiral organ (organ of Corti) in
the cochlea for hearing, and the semicircular canals and the
vestibular organs for equilibrium.

Question 12

The tympanic skin

Answer 12

The tympanic skin splits the exterior ear from the middle ear (eardrum).

Question 13

Eustachian tube

Answer 13

hannel that connects the back of the nose with the middle ear.

Question 14

Cochlea

Answer 14

holds the nerves for hearing.

Question 15

Semicircular canals and Vestibule

Answer 15

This holds receptors for balance.

Question 16

Which part of the ear converts sound waves into vibrations?

Answer 16

Middle ear

Question 17

Which bones are the most delicate bones in your body called

Answer 17

ssicles. These bones, malleus, incus and stapes are the smallest bones in the body that sit in the middle ear between

Question 18

Which tiny bone is attached to the eardrum

Answer 18

Malleus (hammer)

Question 19

Fluid moving in the_____causes you to feel dizzy after you stop spinning.

Answer 19

Semicircular canals

the fluid looped around in a semi-circular canal is positioned at different angles. When you move your head the fluid inside these tubes stays still, just like tea inside a cup stays still when the cup is rotated.

Question 20

What part of your ear allows the ‘popping’ that happens when you fly?

Answer 20

Popping in your ears is when the pressure inside the middle ear is balanced with the pressure outside it, which frequently gives great relief and advances hearing. The Eustachian tube connects the middle ear to the back of your nose and it allows for drainage of fluid and for pressure to be released.

Question 21

cochlea

Answer 21

a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses

Question 22

semicircular canals

Answer 22

three canals within the inner ear that sit in different planes. They contain specialized receptor cells that sense rotations of the head in each plane.

Question 23

The brain perceives signals coming from different neurons in the cochlea as different

Answer 23

Pitches

Question 24

oval window

Answer 24

The membrane that marks the boundary between the middle and inner ears. this receives vibrations from the auditory ossicles.
