The anterior or lingual surface of the epiglottis is curved forward, and covered on its upper, free part by mucous membrane which is reflected on to the sides and root of the tongue, forming a median and two lateral glossoepiglottic folds; the lateral folds are partly attached to …

2024年2月21日 · The epiglottis projects posterosuperiorly from its stem-like base, which is attached to the internal surface of the anterior part of the thyroid cartilage. It is also attached to the base of the tongue via the median glossoepiglottic fold and the pharynx via the lateral glossoepiglottic folds.

Between the median and lateral glossoepiglottic ligaments are small depressions, the valleculae. - The posterior surface of the epiglottis is smooth and coated with respiratory mucosa containing numerous small mucus glands. It is pierced by branches of the internal laryngeal nerve.

The epiglottis is connected to the pharyngeal surface of the tongue and the lateral pharynx by a median glossoepiglottic and two lateral glossoepiglottic ligaments, respectively. Between the median and lateral glossoepiglottic ligaments on both sides are …

The anterior or lingual surface of the epiglottis is curved forward, and covered on its upper, free part by mucous membrane which is reflected on to the sides and root of the tongue, forming a median and two lateral glossoepiglottic folds; The median is unpaired and situated in the midline between the postsulcal part of the tongue and the ...

2023年11月3日 · The mucosa of the lingual surface reflects onto the lateral pharyngeal walls and the pharyngeal surface of the tongue, forming the two lateral glossoepiglottic folds and a median glossoepiglottic fold, respectively. This creates a shallow depression on each side of the median and lateral glossoepiglottic folds, called the epiglottic vallecula ...

2024年1月9日 · The lateral hyoepiglottic ligaments are attached to the lateral edges of the upper portion of the epiglottis, running laterally to the tip of the greater horns of the hyoid bone forming the pharyngoepiglottic folds (lateral glossoepiglottic folds) . The medial ligament is a fibrous fan-shaped band of tissue running in the midline from the upper ...

2024年3月25日 · Midline hyoepiglottic ligament represented by the median glossoepiglottic fold ( vertical arrow) which attaches the epiglottis to the hyoid bone bisects the vallecular region (v). The two lateral pharyngo-epiglottic folds ( oblique arrows) separate the …

thyroid cartilage is connected: above to the hyoid bone via the thyrohyoid membrane; below to the cricoid cartilage via the inferior horn; posteriorly to the paired arytenoid cartilages via the vocal ligaments and thyroartenoid mm.; posteriorly to the epiglottic cartilage via the thyroepiglottic ligament; under the action of the cricothyroid m ...

The epiglottis is attached to the thyroid cartilage by the thyroepiglottic ligament. Epiglottis lies separating the esophagus from the larynx; The aryepiglottic folds and the quadrangular membranes attach to the lower part of the lateral margins of the epiglottis. Most common site of sarcoidosis in larynx.
