25
Extraocular muscles that allows eyes to look downward and medially.

26
Extraocular muscles that allows eyes to look upward and medially.
Inferior oblique muscle
27
The lateral rectus is innervated by what cranial nerve??
Cranial nerve 6 - Abducens
28
The superior oblique muscle is innervated by what cranial nerve?
Cranial nerve 4 - Trochlear nerve
29
All extraocular muscles except the lateral rectus and superior oblique are innervated by what cranial nerve?
Cranial nerve 3 - Oculomotor nerve
30
It is a part of the eyeball that admits and refracts (bends) light.
Cornea
31
It is a part of the eyeball that provides shape and protects inner parts.
Sclera
32
It is a part of the eyeball that regulates the amount of light that enters it.
Iris
33
It is a part of the eyeball that secretes aqueous humor and alters shape of lens for near or far vision (accomodation)
Ciliary body
34
It is a part of the eyeball that provides blood supply and absorbs scattered light.
Choroid
35
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.
Retina
36
It is a part of the eyeball that refracts light.
Lens
37
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.
Anterior cavity
38
It is a part of the eyeball that contains vitreous body that maintains shape of eyeball and keeps retina attached to the choroid.
Vitreous chamber
39
What are the 3 parts of the auditory system?
1, External (outer) ear 2. Middle ear 3. Internal (inner) ear
40
It collects sound waves and channels then inward.
External ear
41
It is a flap of elastic cartilage shaped like the flared end of a trumpet and covered by skin.
Auricle (pinna)
42
It is a curved tube long that lies in the temporal bone and leads to the eardrum.
External acoustic meatus or External auditory canal
43
It is a thin, semitransparent partition between the external auditory canal and middle ear.
Tympanic membrane (eardrum)
44
True or false. Tearing of the tympanic membrane may be due to the pressure from cotton swab, trauma, or middle ear infection.
TRUE
45
It conveys sound vibrations to the oval window.
Middle ear
46
Enumerate the three auditory ossicles. Include their common names.
1. Malleus (hammer) 2. Incus (anvil) 3. Stapes (stirrup)
47
It attaches to the internal surface of the tympanic membrane.
Malleus (hammer)
48
It is the middle bone of the series and articulates with the head of the stapes.
Incus (anvil)
49
It houses the receptors for hearing and equilibrium. Also called the labyrinth.
Internal ear
50
It is the nerve that innervates the ear.
Vestibulocochlear nerve
51
A part of the external ear that collects sound waves.
Auricle (pinna)
52
it directs sound waves to the tympanic membrane.
External auditory canal / acoustic meatus
53
The sound waves cause it to vibrate which in turn causes the malleus to vibrate.
Tympanic Membrane
54
They transmit and amplify vibrations from tympanic membrane to oval window.
Auditory ossicles
55
It equalizes air pressure on both sides of the tympanic membrane.
Eustachian tube
56
It contains a series of fluids, channels, and membranes that transmit vibrations to the spiral organ (Organ of Corti)
Cochlea
57
It includes semicircular ducts, utricle, and saccule, which generate nerve impulses that propagate along the vestibular branch of the cranial nerve 8.
Vestibular apparatus
58
They contain cristae, site for hair cells for dynamic equilibrium.
Semicircular ducts
59
Contains macula, site for hair cells for static equilibrium.
Utricle and saccule
