Question

ta)what do arrows a and b point to? b)what type of sensation do they conduct? this is a model of the ear showing outer, middle and inner ear structures with arrow a pointing to a yellow egg - shaped structure which is a subdivision of a nerve and arrow b pointing to yellow ridged structure which is a subdivision of a nerve. a)cochlear nerve (a): vestibular nerve(b) b)hearing: equilibrium a)vestibular nerve (a): cochlear nerve(b) b)both conduct sensations of equilibrium a)cochlear nerve (a): vestibular nerve(b) b)both conduct sensations of hearing a)vestibular nerve (a): cochlear nerve(b) b)equilibrium: hearing

Explanation:

• The vestibular nerve (A) is responsible for equilibrium. It transmits information related to balance and spatial orientation from the inner ear's vestibular apparatus (semicircular canals, utricle, and saccule) to the brain.
• The cochlear nerve (B) is involved in hearing. It carries auditory information from the cochlea (a spiral - shaped structure in the inner ear that contains hair cells which transduce sound vibrations into neural signals) to the brain.

Answer:

A) vestibular nerve (A), cochlear nerve (B)
B) equilibrium (A), hearing (B)
