External laryngeal nerve The external laryngeal nerve is the smaller, external branch. It descends on the larynx, beneath the sternothyroid muscle, to supply the cricothyroid muscle. The external branch functions to tense the vocal cords by activating the cricothyroid muscle, increasing pitch.
IntraOperative Recurrent Laryngeal Nerve Monitoring * OTOLARYNGOLOGY HOUSTON
The recurrent laryngeal nerve is a branch of the vagus nerve that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left. The right and left nerves are not symmetrical, with the left nerve looping under the aortic arch, and the right nerve looping under the right subclavian artery then traveling.
Recurrent laryngeal nerve Wikipedia
The non-recurrent laryngeal nerve is an anomaly of the RLN because its origin is cervical and it runs a direct course from the vagus nerve to the larynx without looping around any of the above named structures ( 3 ). The origin of the NRLN is cervical and there are three types ( 4 ). Type 1 occurs where the NRLN arises directly from the vagus.

It goes through the thyrohyoid membrane with superior laryngeal artery and vein. The external branch is motor and innervates the anterior cricothyroid muscle and goes along the inferior edge of superior pharynx constrictor; 2) n. laryngeus inferior s. recurrens which is on the left side much longer than on the right side.

Die speziell-viszeromotorischen Fasern des Nervus laryngeus recurrens stammen aus dem Nucleus ambiguus und treten mit der kranialen Wurzel des Nervus accessorius aus dem Hirnstamm aus. Sie kreuzen dann als Ramus internus zum Nervus vagus, der sie im Foramen jugulare aufnimmt.

Nervus laryngeus recurrens 1/3. Synonyms: none. Function. Action of lateral cricoarytenoid muscle Functio musculi cricoarytenoidei lateralis 1/2. Synonyms: Adduction of vocal folds, Adductio plicae vocalis The intrinsic laryngeal muscles, of which the lateral cricoarytenoid is a part, are all involved in the production of sound (phonation).

The recurrent laryngeal nerve (RLN), also known as the inferior laryngeal nerve, is a branch of the vagus nerve (CN X) which has a characteristic loop around the right subclavian artery on the right and the aortic arch on the left before returning up to ascend the tracheoesophageal groove and then the larynx.

Der rechte N. laryngeus recurrens spaltet sich bereits in der Apertura thoracis superior (obere Thoraxöffnung) vom N. vagus ab, umschlingt dann die A. subclavia dexter (Unterschlüsselbeinarterie) von ventral nach dorsal, bevor er im Anschluss unterhalb der A. sublavia dexter retrograd, also zurück nach kranial zieht. Dabei durchläuft er einen Spalt zwischen der Trachea (Luftröhre) und dem.
The NonRecurrent Laryngeal Nerve a metaanalysis and clinical considerations [PeerJ]
The recurrent laryngeal nerve ( RLN) is a branch of the vagus nerve ( cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left.

The Autonomic Nervous System As a convenience in understanding the nervous system, we subdivide it into anatomic and functional groups that we refer to as systems. Examples of these are autonomic, limbic, reticular formation, visual, pyramidal, and extrapyramidal. The anatomic components of the autonomic nervous system (ANS) are controversial.
The Recurrent Laryngeal Nerves and the Thoracic Surgeon
A nonrecurrent laryngeal nerve (NRLN) is a rare anatomical variation in which the nerve enters the larynx directly from the cervical vagus nerve, without descending to the thoracic level [ 2 ]. It has been reported in 0.3-0.8% of the population on the right side, being extremely rare on the left side (0.004%) [ 3 ].
Recurrent Laryngeal Nerve Anatomy
The recurrent laryngeal nerve (RLN) branches off the vagus nerve (cranial nerve X) and has an indirect course through the neck. It supplies innervation to all of the intrinsic muscles of the larynx, except for the cricothyroid muscles, as well as sensation to the larynx below the level of the vocal cords.

The recurrent laryngeal nerve (n. laryngeus recurrens), which contains branchiomotor fibers. This branch arises from the trunk of the vagus nerve in the thoracic cavity, but then it returns to the neck, looping around the aortic arch (arcus aortae) inferiorly from the left, and the subclavian artery (arteria subclavia) from the right.

PMID: 17972539. In this study, the authors remind the readers the problem traditionally discussed in the thyroid gland surgery--protection of the nervus laryngeus recurrens (NLR) from iatrogenic damage. The aim of this study is to point out some anatomical details on the course of the recurrent nerve (Ref 4). Humans. Intraoperative Complications.
