Hair Cells

• Hair Cells

• Cochlear Ganglion Cells

• Dorsal and ventral Cochlear Nuclei

• Trapezoid Body Complex

• MNTB Medial Nucleus of Trapezoid body- Directional detection
• MSO Medial Superior Olive- Ascending pathway to inferior colliculus
• LSO Lateral Superior Olive- Efferent pathway forming the Olivo-cochlear bundle that projects out to the cochlea.

• Inferior Colliculus- sends auditory signals to the medial geniculate as well as descending projections to the LSO.

• Medial Geniculate Body- Thalamic relay nucleus to Cortex.

• Transverse Gyri of Heschl- Primary auditory cortex. On the superior temporal gyrus within the lateral fissure.
