NERVUS PTERYGOIDEUS Meaning and Definition

1. Nervus pterygoideus, also known as the pterygoid nerve, is a term used in anatomy to describe one of the nerves associated with the human or animal craniofacial region. This nerve is a branch of the trigeminal nerve (cranial nerve V), specifically, the mandibular division (V3). The trigeminal nerve is the fifth cranial nerve responsible for providing sensory information from the face and controlling the muscles involved in chewing.

   The nervus pterygoideus emerges from the mandibular nerve in the infratemporal fossa, a depression located on the lateral aspect of the skull. From there, it descends inferiorly, supplying sensory innervation to various areas of the face and oral cavity. This includes the skin of the cheek, lower lip, and chin, as well as the lining of the mouth.

   The nerve also plays a critical role in motor function as it innervates the tensor veli palatini muscle, responsible for the dilation of the eustachian tube. This helps equalize pressure between the middle ear and the outside environment, preventing discomfort and potential damage.

   Understanding the nerves in the head and face is crucial for functional and diagnostic purposes. Knowledge of the nervus pterygoideus aids in identifying the sources of pain or dysfunction in the craniofacial region, thus facilitating proper treatment and management.

2. Pterygoid nerve, one of two motor branches, externus and internus, of the buccinator, supplying the external and internal pterygoid muscles.

Etymology of NERVUS PTERYGOIDEUS

The word "nervus pterygoideus" is derived from Latin and Greek.

The term "nervus" comes from Latin, meaning "nerve". It can be traced back to the Proto-Indo-European root "*snewh₁-", which means "to shake" or "to be excited". This root evolved into the Latin word "nervus", referring to the nerves that transmit signals and impulses throughout the body.

"Pterygoideus" is a Latin word that originates from the Greek term "pteryx", meaning "wing" or "fin". In anatomy, "pterygoideus" is usually used in reference to the pterygoid muscles located in the region of the skull. These muscles are named so due to their shape, which resembles wings or fins.
