The Organ of Corti contains two types of hair cells, inner and outer.
( Inner Hair Cells, Outer Hair Cells ) are primarily a source of afferent signals in the cochlear nerve.
( Outer Hair Cells, Inner Hair Cells ) primarily receive efferent outputs from the CNS to control hair stiffness and amplify membrane vibration

Explanation

Question 20 of 22

1

Fill the blank space to complete the text.

The 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?

Explanation

Question 21 of 22

1

Fill the blank space to complete the text.

Each 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 .
