Study Notes
Auditory Pathway
- Cell bodies of the first-order neurons are located in the spiral ganglion within the cochlea.
Transmission of Auditory Information
- Main pathway through which auditory information reaches the primary auditory cortex: cochlear nucleus → superior olivary complex → lateral lemniscus → inferior colliculus → medial geniculate nucleus → primary auditory cortex.
Non-Lemniscal Pathway
- Function of the non-lemniscal pathway: auditory processing and integration of auditory information with other sensory modalities.
First-Order Neurons
- Central axons of the first-order neurons travel within the auditory nerve (VIII cranial nerve) to reach the cochlear nucleus.
Auditory Nerve
- The auditory nerve (VIII cranial nerve) carries auditory information to the central nervous system.
Osseous Spiral Lamina
- Function of the osseous spiral lamina: support and organization of the auditory receptor cells (hair cells) in the cochlea.
