A)retinal;cochlea
B)hair;saccule
C)hair;semicircular canals
D)ganglion;olfactory mucosa
E)basiliar;tectorial membrane

Question

Quizplus · Accepted Answer

The hair cells in the semicircular canals detect rotational acceleration of the head and are responsible for sensing changes in head position during sudden stops or turns. They send signals to the brain via the vestibular nerve to help maintain balance and coordinate eye movements. Retinal cells are responsible for visual processing, while hair cells in the saccule and utricle detect linear acceleration and orientation with respect to gravity. Ganglion cells in the olfactory mucosa are responsible for transmitting information about smell to the brain, and basilar cells in the cochlea detect sound vibrations. The tectorial membrane is a gelatinous structure that overlies the hair cells in the cochlea and helps to amplify sound signals, but it is not directly involved in detecting head motion.
