Question

Which of the following statements is FALSE about the organ of corti?

A. It contains 2 separate membranes
B. It contains both inner and outer hair cells
C. The outer hair cells and are attached to efferent axons
D. The inner hair cells are connected to afferent axons
E. The tectoral membrane moves up and down with a sound wave

Answer 1

The false statement about the Organ of Corti is that the outer hair cells are attached to efferent axons; they are actually primarily connected to afferent axons. Option e.

Step-by-step explanation:

The false statement about the Organ of Corti is C, 'The outer hair cells and are attached to efferent axons.' In fact, the outer hair cells are primarily attached to afferent axons, although they also receive some efferent innervation, primarily for modulating sensitivity. Inner hair cells, conversely, are connected to afferent axons and are the main source of auditory information to the brain. The tectorial membrane indeed moves in response to sound waves, moving across the stereocilia of both inner and outer hair cells.
