13 Questions
Where is the macula of the utricle located?
On a horizontal planar layer
Which part of the vestibular system is important in stabilizing head and body posture?
Otolith organs
What is the function of the otolith organs?
Linear acceleration/deceleration & static head position/angle relative to the gravitational axis
Where are the three semicircular canals (SCC) located?
Inner ear structure: labyrinth
What is the location of the macula of the saccule?
On a vertical layer
What is the function of the semicircular canals (SCC)?
Rotational acceleration/deceleration
Where is the sensory epithelium located?
In the utricle and saccule (otolith organs) as macula
What is the function of the gelatinous cupula in the macula of the saccule and utricle?
To detect linear acceleration and head tilts
What is the role of otoliths in the vestibular system?
To add mass and move with gravity, aiding in the detection of linear acceleration
What is the function of the crista within the semicircular canals?
To detect rotational movements
Select the correct statement on vestibular system.
Vestibular sensory epithelia can be found in macula and crista
Select the correct function of otoliths or otoconia
Enhance the movement sensing by hair cells
Select the correct statement on vestibular pathway and body balance control
Vestibulo-spinal reflex adjusts muscles in the trunk and limbs to maintain body posture balance
Test your knowledge of the inner ear's vestibular system and its role in processing sensory information related to balance, spatial orientation, and head position. Explore the labyrinth's otolith organs and semicircular canals in this quiz.
