Gag Reflex | Procedure & Results Interpretation

The video tutorial explains the gag reflex, its sensory and motor components, and how it involves multiple cranial nerves. It details the assessment process using a tongue depressor and describes the reflex arc, including the role of various nuclei and nerves. The tutorial also covers indicators of a normal gag reflex and how to identify abnormalities, such as asymmetry and deviations, which may indicate motor neuron lesions.
