The phrase "nervus alveolaris superior" is a Latin term that refers to the superior alveolar nerve, which supplies sensation to the upper teeth and gums. The spelling of this word can be broken down using the International Phonetic Alphabet (IPA). The letter "v" in "nervus" is pronounced as a voiced labiodental fricative (/v/), while the "s" in "alveolaris" is pronounced as an unvoiced alveolar fricative (/s/). The "a" in "superior" is pronounced as a low front vowel (/æ/).
The term "nervus alveolaris superior" refers to a nerve located within the human body, specifically in the upper jaw. It is an anatomical component of the maxillary nerve, which is a division of the trigeminal nerve, also known as the fifth cranial nerve. The nervus alveolaris superior is responsible for transmitting sensory information from the upper jaw to the brain.
The nerve receives input from various structures in the upper jaw, including the maxillary teeth, gums, and surrounding oral tissues. It registers sensations such as touch, temperature, and pain, allowing individuals to perceive stimuli in this region of the face.
The nervus alveolaris superior branches off from the maxillary nerve within the pterygopalatine fossa, a cavity located behind the maxilla bone. From there, it travels through a small opening called the infraorbital foramen, situated on the floor of the eye socket. The nerve then continues downwards and forwards along the maxillary sinus, eventually reaching the upper teeth.
The understanding of the nervus alveolaris superior is crucial in various medical fields, including dentistry, oral surgery, and maxillofacial surgery. By knowing its trajectory and distribution, healthcare professionals can perform procedures in a precise and safe manner, minimizing the risk of nerve injury during dental treatments or surgeries in the upper jaw.
Superior alveolar nerve, posterior dental nerve, a branch (sometimes two branches) of the maxillary in the pterygopalatine canal, passing through the pterygomaxillary fissure and supplying gums and molar teeth.
