26
Q

Extraocular muscles that allows eyes to look upward and medially.

A

Inferior oblique muscle

27
Q

The lateral rectus is innervated by what cranial nerve??

A

Cranial nerve 6 - Abducens

28
Q

The superior oblique muscle is innervated by what cranial nerve?

A

Cranial nerve 4 - Trochlear nerve

29
Q

All extraocular muscles except the lateral rectus and superior oblique are innervated by what cranial nerve?

A

Cranial nerve 3 - Oculomotor nerve

30
Q

It is a part of the eyeball that admits and refracts (bends) light.

A

Cornea

31
Q

It is a part of the eyeball that provides shape and protects inner parts.

A

Sclera

32
Q

It is a part of the eyeball that regulates the amount of light that enters it.

A

Iris

33
Q

It is a part of the eyeball that secretes aqueous humor and alters shape of lens for near or far vision (accomodation)

A

Ciliary body

34
Q

It is a part of the eyeball that provides blood supply and absorbs scattered light.

A

Choroid

35
Q

It is a part of the eyeball that receives light and converts into receptor potentials and nerve impulses. Output to brain is via axons of ganglion cells which form the optic (II) nerve.

A

Retina

36
Q

It is a part of the eyeball that refracts light.

A

Lens

37
Q

It is a part of the eyeball that contains the aqueous humor that helps maintain shape of eyeball and supplies oxygen and nutrients to lens and cornea.

A

Anterior cavity

38
Q

It is a part of the eyeball that contains vitreous body that maintains shape of eyeball and keeps retina attached to the choroid.

A

Vitreous chamber

39
Q

What are the 3 parts of the auditory system?

A

1, External (outer) ear

  1. Middle ear
  2. Internal (inner) ear
40
Q

It collects sound waves and channels then inward.

A

External ear

41
Q

It is a flap of elastic cartilage shaped like the flared end of a trumpet and covered by skin.

A

Auricle (pinna)

42
Q

It is a curved tube long that lies in the temporal bone and leads to the eardrum.

A

External acoustic meatus or External auditory canal

43
Q

It is a thin, semitransparent partition between the external auditory canal and middle ear.

A

Tympanic membrane (eardrum)

44
Q

True or false.

Tearing of the tympanic membrane may be due to the pressure from cotton swab, trauma, or middle ear infection.

A

TRUE

45
Q

It conveys sound vibrations to the oval window.

A

Middle ear

46
Q

Enumerate the three auditory ossicles. Include their common names.

A
  1. Malleus (hammer)
  2. Incus (anvil)
  3. Stapes (stirrup)
47
Q

It attaches to the internal surface of the tympanic membrane.

A

Malleus (hammer)

48
Q

It is the middle bone of the series and articulates with the head of the stapes.

A

Incus (anvil)

49
Q

It houses the receptors for hearing and equilibrium. Also called the labyrinth.

A

Internal ear

50
Q

It is the nerve that innervates the ear.

A

Vestibulocochlear nerve

51
Q

A part of the external ear that collects sound waves.

A

Auricle (pinna)

52
Q

it directs sound waves to the tympanic membrane.

A

External auditory canal / acoustic meatus

53
Q

The sound waves cause it to vibrate which in turn causes the malleus to vibrate.

A

Tympanic Membrane

54
Q

They transmit and amplify vibrations from tympanic membrane to oval window.

A

Auditory ossicles

55
Q

It equalizes air pressure on both sides of the tympanic membrane.

A

Eustachian tube

56
Q

It contains a series of fluids, channels, and membranes that transmit vibrations to the spiral organ (Organ of Corti)

A

Cochlea

57
Q

It includes semicircular ducts, utricle, and saccule, which generate nerve impulses that propagate along the vestibular branch of the cranial nerve 8.

A

Vestibular apparatus

58
Q

They contain cristae, site for hair cells for dynamic equilibrium.

A

Semicircular ducts

59
Q

Contains macula, site for hair cells for static equilibrium.

A

Utricle and saccule
