The thyrohyoid muscle is part of the lower hyoid (infrahyoid) musculature and is innervated by the ansa cervicalis. It is active during swallowing, closing the larynx to prevent food or fluid from entering the airway. Disorders of the thyrohyoid muscle can therefore lead to increased swallowing. What is the thyrohyoid muscle? The thyrohyoid muscle is … Thyrohyoid Muscle: Structure, Function & Diseases

Causes include diseases such as multiple sclerosis. What is the Gordon reflex? The physician triggers the reflex movement by kneading the patient’s calves. The big toe then … Gordon Reflex: Function, Tasks, Role & Diseases
The Mendel-Bechterew reflex is a foot reflex from the Babinski group that is categorized as a pyramidal tract sign. The pathologic reflex movement may suggest damage to the central motor neurons. Such damage presents, for example, in the context of amyotrophic lateral sclerosis (ALS). What is the Mendel-Bechterew reflex? For example, when the top of … Mendel-Bechterew Reflex: Function, Tasks, Role & Diseases
