Anatomy, Head and Neck: Pharyngeal Muscles
2024年5月25日 · This muscular tube is divided into the oropharynx, nasopharynx, and laryngopharynx. Pharyngeal muscles are organized into an outer circular layer and an inner longitudinal sheet surrounding the lumen. The outer circular layer consists of the superior, middle, and inferior pharyngeal constrictor muscles (see Image. Pharyngeal Constrictors).

2024年7月17日 · Most laryngeal structures develop from the 4th pharyngeal arch, including the thyroid cartilage, cuneiform cartilages, part of the epiglottis, SLN, cricopharyngeus muscles, and cricothyroid muscles, and the 6th pharyngeal arch, including the RLNs, the cricoid, arytenoid, and corniculate cartilages, and the remaining intrinsic muscles.
Muscles of the larynx: Anatomy, function, diagram - Kenhub
2023年10月30日 · There are many muscles that either make up a certain part of the laryngeal structure inside the neck, or that sit adjacent to it and aid in its function. These muscles produce the movements of the larynx and its cartilages, thus enabling the proper air conduction, speech, movements of the epiglottis and airways protection.

2024年5月25日 · The pharynx is part of the digestive system posterior to the oronasal cavity and larynx. This muscular tube is divided into the oropharynx, nasopharynx, and laryngopharynx. Pharyngeal muscles are organized into an outer circular layer and an inner longitudinal sheet surrounding the lumen.
The muscles of the pharynx and larynx subserve critical airway, deglutitive and communication functions. The laryngeal muscles protect the lower airway from invasion and allow voice production for the purposes of communication. The mus-cles of the pharynx serve deglutitive functions by creating appropriate pressures to
