Correct option is B
The auditory pathway follows a hierarchical sequence from peripheral to central processing. Sound information travels via (a) auditory nerve (cranial nerve VIII) to (b) cochlear nuclei in the medulla, then to (c) superior olives for binaural processing. Signals ascend through (d) lateral leminiscus to the midbrain's (e) inferior colliculi, then to the thalamic (f) medial geniculate nuclei, and finally to (g) primary auditory cortex (A1) in the temporal lobe for conscious auditory perception.
Information Booster:
● Auditory nerve: Carries neural impulses from cochlear hair cells to brainstem
● Cochlear nuclei: First central relay station for all auditory information
● Superior olives: Critical for sound localization through interaural time and intensity differences
● Inferior colliculi: Midbrain integration center for auditory reflexes and processing
● Medial geniculate nucleus: Thalamic relay to cortex, part of the auditory radiation
● Primary auditory cortex (A1): Tonotopically organized cortical area for conscious sound perception
