What is the auditory pathway?

The auditory pathway starts at the cochlear nucleus, then the superior olivary complex, then the inferior colliculus, and finally the medial geniculate nucleus. The information is decoded and integrated by each relay nucleus in the pathway and finally projected to the auditory cortex.

What are the parts of the auditory pathway?

The auditory system processes how we hear and understand sounds within the environment. It is made up of both peripheral structures (e.g., outer, middle, and inner ear) and brain regions (cochlear nuclei, superior olivary nuclei, lateral lemniscus, inferior colliculus, medial geniculate nuclei, and auditory cortex).

What is the correct pathway for auditory transduction?

sound waves → tympanic membrane (ear drum) → malleus → incus → stapes → oval window → vestibular canal → basilar membrane → stereocilia of hair cells → potassium ions → calcium ions → neurotransmitters → action potentials over cochlear nerve.

How do you remember the auditory pathway?

Just remember that the auditory pathway starts with the auditory nerve, goes to its nucleus (cochlear nucleus) and then suddenly turns into slime (visualise this) – SLIMA.
