Vestibular Sensation

Vestibular Sensation

To the tune of “Last Christmas” by Wham

[Chorus]
Vestibular sensation
Provides perception of orientation
Three sensory modalities
Interact to provide this sense
Vestibular sensation
Provides perception of orientation
Three sensory modalities
Interact to provide this sense

[Verse 1] 
Three semicircular canals
Posterior, anterior, and horizontal
They are involved in the detection
Of angular motion

 [Verse 2]
Rely on push-pull symmetry
Hair cell responses are complementary
Cells in the opposite ears are paired
Altering release of neurotransmitters

[Chorus] 
Vestibular sensation
Provides perception of orientation
Three sensory modalities
Interact to provide this sense
Vestibular sensation
Provides perception of orientation
Three sensory modalities
Interact to provide this sense

[Verse 3] 
Two otolith organs
Detect gravity and linear motion
Horizontal is the utricle
Vertical is the saccule

[Verse 4] 
Larger acceleration or gravitational shear
Causes greater deflection of hair cells in each ear
By moving the otoconia more

 [Chorus] 
Vestibular sensation
Provides perception of orientation
Three sensory modalities
Interact to provide this sense

 [Verse 5]
Larger accelerations or gravitational shear
Causes greater deflection of hair cells in each ear
By moving the otoconia more
