Placode Dorsolateral

The dorsolateral placode, also known as the dorsolateral placoid nerve (p. dorsolateralis, inn. laryngeus superior), is one of three nerves that exit the larynx and enter the laryngeal part of the pharynx.

The dorsolateral nerve is a continuation of the superior laryngeal nerve and is responsible for innervation of the lateral part of the larynx, including the cricoid and arytenoid glands. This nerve also innervates the muscles of the larynx, such as the cricothyroid, cricoid, and arytenthyroid muscles.

The placode dorsolateral is also a branch of the inferior laryngeal nerve, which emerges from the laryngeal part of the pharynx and innervates the medial part of the larynx. Thus, the dorsolateral and inferior laryngeal nerves form two branches emerging from the larynx, which innervate different parts of the larynx.

The function of the dorsolateral nerve is to regulate the secretion of laryngeal mucus, which protects the larynx from irritation and prevents it from drying out. In addition, it is also responsible for regulating the muscle tone of the larynx and maintaining its normal functioning.

Thus, the dorsolateral nerve plays an important role in regulating laryngeal function and maintaining laryngeal health. Violation of its function can lead to various diseases of the larynx, such as laryngitis, laryngitis and laryngotracheitis.

Overall, the dorsolateral nerve is an important nerve that is responsible for many functions of the larynx and can be susceptible to various diseases. Therefore, it is important to monitor the health of this nerve and take measures to prevent its damage.



Dorsolateral placode - (piriformis dorsalis, lat., syn. stylochasia) pyramidal accessory nerve - a nerve from the lumbosacral plexus, runs along the lateral surface of the femur to the lower gluteal region, innervating the lower gluteal muscle group.

The dorsal part of the placode is adjacent to the lateral side of the origin of the sciatic nerve from the sacral canal. At this point, the placode is connected to the eversion canal and is partially covered by it. Lower
