Masseter reflex
From WikiLectures
The Masseter reflex is elicited by tapping the examiner's finger with a mallet placed across the examinee's chin, with the patient's [[oral cavity|mouth] slightly open. The equipment of this reflex belongs to the examination of the function n. trigeminus. In a healthy patient, the response is a quick and reasonable advance of closing the lower jaw, which is given by the contraction of the muscle of mastication.[1]
'Increased masseter reflex may be present in patients with pseudobulbar syndrome, in bulbar syndrome the reflex is absent. Furthermore, increased reflexes are common in patients with amyotrophic lateral sclerosis.[2]
