The Recurrent Laryngeal Nerves and the Thoracic Surgeon
Pin on Myradiology
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.

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.

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.

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.
Nervus Laryngeus Recurrens Human Anatomy Human Head And Neck
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 ].

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 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. Summary
Anatomía de la laringe
The Recurrent Nerve (n. recurrens; inferior or recurrent laryngeal nerve) arises, on the right side, in front of the subclavian artery; winds from before backward around that vessel, and ascends obliquely to the side of the trachea behind the common carotid artery, and either in front of or behind the inferior thyroid artery. On the left side, it arises on the left of the arch of the aorta.

The aim of this study was to define the origin, course, caliber and relations of the left recurrent laryngeal nerve (N Laryngeus recurrens) in order to localize the nerve during surgery for esophageal atresia. Eighteen anatomic specimens were dissected and 12 surgical cases were analysed. Left recurrent laryngeal nerve palsy after this.

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.

Introduction. The recurrent laryngeal nerve is a cervical branch of the vagus nerve that supplies motor, sensory and parasympathetic nerve fibers to the larynx [Citation 1, Citation 2].Non-recurrence of the nerve is a rare anatomical variant [Citation 3].The first case was reported in 1823 by Stedman [Citation 4].This variation is constantly associated with vascular malformations due to an.

1. Introduction. The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (CN X). It carries sensory, motor, and parasympathetic fibers to the laryngeal structures [].It is the main motor nerve of all intrinsic laryngeal muscles, except the cricothyroid, which receives its innervation via the external laryngeal nerve [].The RLN has a different course on the left and right side of the.

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.
