The intermediate nerve, also known as the nervus intermedius, is a crucial cranial nerve that plays a significant role in the functions of the head and neck. Synonyms for the intermediate nerve include the cranial nerve VII.5, the nervus intermedullaris, and the nervus facialis intermedius. In some cases, it may be referred to as the sensory root of the facial nerve, and is distinct from the motor roots of this nerve. The intermediate nerve is responsible for carrying out necessary functions such as taste, glandular secretion, and some motor control, making it an essential component of the overall activity of the cranial nerve system.
