[blank_start]Malleus[blank_end]
[blank_start]Incus[blank_end]
[blank_start]Stapes[blank_end]- AMalleus
- BIncus
- CStapes
3[blank_start]Tensor Tympani[blank_end]: Reduces the noise of loud sounds such as chewing or shouting
[blank_start]Stapedius[blank_end]: Dampens vibrations of one of the ossicles to control the amplitude of sound waves being projected into the inner ear- ATensor Tympani
- BTympanic Membrane
- CStapedius
4The Stapes bone connected to the inner ear via the [blank_start]oval[blank_end] window
- Aoval
- Bround
- Ccircular
5Label the anatomy of the cochlea.
- ACochlear Nerve
- BOval Window
- CRound Window
- DScala Vestibuli
- EScala Media
- FScala Tympani
- GOrgan of Corti
6[blank_start]Reissner's[blank_end] Membrane separates the scala vestibuli from the scala media
The [blank_start]Basilar[blank_end] Membrane separates the scala media from the scala tympani- AReissner's
- BBasilar
- CCorti's
- DVestibular
- EBasilar
- FReissner
- GVestibular
- HCorti
7Scala vestibuli meets [blank_start]oval[blank_end] window
Scala tympani meets [blank_start]round[blank_end] window- Aoval
- Bround
8The point at which scala vestibuli meets scala tympani is called the [blank_start]helicotrema[blank_end]
- Ahelicotrema
9The group of nerve cells in the cochlea that serve the sense of hearing by sending a representation of sound from the cochlea to the brain is called the [blank_start]spiral ganglion[blank_end]
- Aspiral ganglion
10The Organ of Corti contains two types of hair cells, inner and outer.
[blank_start]Inner Hair Cells[blank_end] are primarily a source of afferent signals in the cochlear nerve.
[blank_start]Outer Hair Cells[blank_end] primarily receive efferent outputs from the CNS to control hair stiffness and amplify membrane vibration- AInner Hair Cells
- BOuter Hair Cells
- COuter Hair Cells
- DInner Hair Cells
11The membrane between the scala vestibuli and the organ of corti is called the [blank_start]tectorial[blank_end] membrane.
- Atectorial
12In regard to the auditory pathway, the Thalamic relay between the Inferior Colliculus and the Primary Auditory Cortex is via the [blank_start]Medial Geniculate[blank_end] Nucleus
- AMedial Geniculate
13Which of the following coloured areas of the brain shows the Primary Auditory Cortex?
- ABlue
- BRed
- CGreen
- DOrange
- EYellow
14The lateral and medial [blank_start]superior[blank_end] [blank_start]olivary[blank_end] nuclei are responsible for locating a sound in space
- Asuperior
- Binferior
- Colivary
- Dlemniscal
- Egeniculate
- Fcollicular
15Fill in the the Central Auditory Pathway, from the cochlea to the primary auditory cortex:
Cochlea
[blank_start]Cochlear Nerve[blank_end]
[blank_start]Vestibulocochlear Nerve[blank_end]
[blank_start]Medial/Lateral Superior Olivary Nuclei[blank_end]
[blank_start]Inferior Colliculus[blank_end]
[blank_start]Medial Geniculate Nucleus[blank_end]
Primary Auditory Cortex- ACochlear Nerve
- BVestibulocochlear Nerve
- CMedial/Lateral Superior Olivary Nuclei
- DInferior Colliculus
- EMedial Geniculate Nucleus
16The function of the vestibular organ is to establish an individual's orientation in the world (which way am I going, which was is up, etc). It does this by measuring acceleration.
Head angular acceleration is measured by the [blank_start]semicircular canals[blank_end]
Head linear acceleration is measured by the [blank_start]saccule and utricle[blank_end]- Asaccule and utricle
- Bsemicircular canals
- Ccochlea
17Which vestibular organ(s) detects rotational motion of the head?
- AThe Semicircular Canals
- BThe Utricle
- CThe Saccule
18Label the semicircular canal and its contents shown below.
- ACupula
- BAmpulla
19In terms of the otolith organs:
The [blank_start]Saccule[blank_end] detects movement in the vertical (sagittal) plane
The [blank_start]Utricle[blank_end] detects movement in the horizontal plane- AUtricle
- BSaccule
20The otoconia are small crystals which lie on the otolithic membrane dictate the movement of the cilia of the otolithic hair cells.
What chemical substance are these otoconia crystals made of?
[blank_start]Calcium Carbonate[blank_end]- ACalcium Carbonate
21Each otolith organ (saccule & utricle) contains a central dividing line that separates it into two halves, each side with opposing polarity to the other. This allows each otolith organ to have multidirectional sensitivity (e.g. utricle can detect left and right).
This dividing line is known as the [blank_start]Striola[blank_end].
- AStriola
22Vestibular Reflexes:
[blank_start]Vestibulo-ocular Reflex[blank_end] - Keeps eyes still while the head moves
[blank_start]Vestibulo-colic Reflex[blank_end] - Keeps the head still in space while you walk
[blank_start]Vestibulo-spinal Reflex[blank_end] - Adjusts posture for rapid changes in position- AVestibulo-ocular Reflex
- BVestibulo-colic Reflex
- CVestibulo-spinal Reflex
- DVestibulo-cranial Reflex
