Understand the Problem
The image discusses the concept of the acoustic reflex arc as described by Borg in 1973. It provides an overview of the anatomical and physiological functions involved in the acoustic reflex, including the roles of various muscles and pathways in response to sound stimuli.
Answer
The reflex arc activates stapedius muscles via auditory nerve pathways.
The acoustic reflex arc begins at the auditory nerve, moving to the ventral cochlear nucleus, then to the superior olivary complex, and finally involves motor activation of the stapedius muscles.
Answer for screen readers
The acoustic reflex arc begins at the auditory nerve, moving to the ventral cochlear nucleus, then to the superior olivary complex, and finally involves motor activation of the stapedius muscles.
More Information
The acoustic reflex arc is crucial for protecting the ear from loud sounds by contracting the stapedius muscle, reducing the transmission of sound vibrations.
Tips
Avoid confusing the sensory and motor pathways; both are integral to the arc's function.
