Aug 8, 2023 · The median sulcus divides the tongue centrally, beginning at the apex of the tongue tip and extending to the foramen cecum, which creates the apex of a V-shaped groove, which is called the sulcus terminalis. The papillae are tiny protuberances on the dorsal tongue, especially on the anterior two-thirds, classified into three types.
Development of the Pituitary, Tongue and Thyroid
May 20, 2024 · The thyroid gland begins development as a proliferation of endodermal cells between the cupola and tuberculum impar of the primitive tongue (the site of the future foramen cecum). This proliferation of cells bifurcates and descends …
Tongue - Wikipedia
The human tongue is divided into anterior and posterior parts by the terminal sulcus, which is a "V"-shaped groove. The apex of the terminal sulcus is marked by a blind foramen, the foramen cecum, which is a remnant of the median thyroid diverticulum in early embryonic development.

Sep 27, 2023 · This triangular protuberance is located cranial to the foramen cecum (opening of the thyroglossal duct) and is later joined by the two distal tongue buds (lateral lingual swellings). The lateral lingual swellings are oval enlargements …

Aug 21, 2023 · The thyroid gland begins to develop on the floor of the embryologic pharynx at the point called the foramen cecum, which is located at the dorsum of the posterior tongue. The developing gland then relocates to its ultimate destination in the anterior neck by migrating down the thyroglossal duct anterior to the hyoid and thyroid cartilages ...
Thyroglossal duct pathology and mimics - Insights into Imaging
Feb 6, 2019 · Critical anatomic landmarks of thyroglossal duct anomalies and ectopic thyroid tissue include the foramen cecum at the tongue base, hyoid bone, thyroid cartilage, and strap musculature. The purpose of this article is to review the common and variant forms of thyroglossal duct anomalies.
Foramen cecum of tongue - e-Anatomy - IMAIOS
Gallery. Anatomical hierarchy. The median sulcus divides the dorsum of the tongue into symmetrical halves; this sulcus ends behind, about 2.5 cm. from the root of the tongue, in a depression, the foramen caecum, from which a shallow groove, the sulcus terminalis, runs lateralward and forward on either side to the margin of the tongue.
Embryology, Thyroid - StatPearls - NCBI Bookshelf
May 1, 2023 · Normally, the thyroglossal duct degenerates by the tenth week of gestation with only the foramen cecum to indicate its former existence. In some instances, incomplete obliteration of the duct can lead to abnormalities, including thyroglossal duct cysts, lingual thyroid, or a pyramidal lobe.

The foramen cecum is located at the midline just anterior to the terminal sulcus on the body of the tongue. Now, this structure is an embryological remnant of the thyroglossal duct and is formed during the descent of the thyroid gland during embryological development.
