Vestibular System
- 1.
From the answer choices below, which one is NOT a function of the vestibular system?
- A.
Balance
- B.
Monitors changes of position of the head.
- C.
Coordinates eye movement with head movement.
- D.
Pain perception
- E.
Posture
Correct Answer
D. Pain perceptionExplanation
Choices A, B, C, and E are all functions of the vestibular system. Choice D, pain perception, is overseen by the somatosensory system.Rate this question:

The vestibular system progresses more rapidly than the sense of hearing.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The vestibular system is responsible for our sense of balance and spatial orientation, while the sense of hearing is responsible for our ability to perceive sound. The vestibular system develops earlier in life compared to the sense of hearing. During fetal development, the vestibular system begins to develop around the 5th week, while the sense of hearing starts to develop around the 18th week. This suggests that the vestibular system progresses more rapidly than the sense of hearing, making the statement true.Rate this question:

What do the semicircular canals detect?
- A.
Linear movements
- B.
Head turns
- C.
Head tilts
- D.
Body's position with respect to gravity
Correct Answer
B. Head turnsExplanation
Choices A, C, and D are all detected by the otolith organs.Rate this question:
-
- 4.
What are the two otolith organs?
- A.
Cochlea and cilia
- B.
Utricle and cochlea
- C.
Saccule and utricle
- D.
Cilia and saccule
Correct Answer
C. Saccule and utricleExplanation
The two otolith organs are the saccule and utricle. These organs are part of the vestibular system in the inner ear and are responsible for detecting linear acceleration and head position. The saccule detects vertical acceleration, while the utricle detects horizontal acceleration. Together, they play a crucial role in maintaining balance and equilibrium. The cochlea, on the other hand, is responsible for hearing, and cilia are tiny hair-like structures found in various parts of the body, including the inner ear.Rate this question:

A child's vestibular system has a peak in sensitivity between what period?
- A.
Birth to three months
- B.
Six to twelve months
- C.
One year to two and a half years
- D.
Puberty
Correct Answer
B. Six to twelve monthsExplanation
During the period of six to twelve months, a child's vestibular system reaches its peak sensitivity. The vestibular system is responsible for maintaining balance and spatial orientation. At this age, infants are developing their motor skills and beginning to explore their surroundings by crawling, standing, and walking. The heightened sensitivity of the vestibular system during this period helps infants to navigate and adapt to their environment more effectively.Rate this question:

A baby with a defect in their vestibular system is more likely to be born in the breech position.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The vestibular system is responsible for maintaining balance and spatial orientation. If a baby has a defect in their vestibular system, it can affect their ability to properly position themselves in the womb. This can increase the likelihood of them being in the breech position, where their buttocks or feet are positioned to be delivered first instead of the head.Rate this question:

Increases language development
- B.
Increases visual alertness
- C.
Increases development of reflexes and motor skills
- D.
Helps a baby's overall behavioral state
Correct Answer
A. Increases language development -
