NROC64H3 Lecture Notes - Lecture 7: Superior Olivary Complex, Ear Canal, Auditory Cortex
Document Summary
Divided into two subsystems: 1. peripheral auditory system: outer ear, middle ear and inner ear, 2. central auditory system: from the cochlear nucleus up to the primary auditory cortex. Sound waves enter the ear and travel thru external auditory canal before striking the ear drum, and causing it to vibrate. Stapes ow waves of sound thru cochlear fluid ooc into motion causing fibers to resonate high frequency near ow and low f near end. Middle ear infection throat; common in children = everything a lot shorter in a child; area in canal a lot shorter and easier for germs to get there because so small. The auditory nerve combines with the vestibular nerve forming cranial nerve viii or the vestibulocochlear nerve. The cochlear nucleus is the first site of the neuronal processing of the newly converted data from the inner ear.
