An infant who is incapable of verbally communicating likes to gaze into a persons face instead of other visual stimuli Movement of the face is controlled by two cranial nerves: Facial Nerve: controls the superficial muscles attached to the skin and primarily responsible for facial expressions o Has 5 major branches, each serves a different part of the face; o Originate in the two facial nuclei, which dont communicate with each other, that receive info from primary motor cortex located in pre-central gyrus Trigeminal Nerve: controls the deeper facial muscles attached to the bones of the head that are responsible for chewing food and speaking www.notesolution.com
