Hypopharyngeal eminence

From WikiMD's Wellness Encyclopedia

Hypopharyngeal eminence is a structure that forms during the embryonic development of vertebrates. It is located in the pharynx, specifically in the lower part of the pharynx known as the hypopharynx. The hypopharyngeal eminence is formed from the third and fourth pharyngeal arches.

Etymology[edit | edit source]

The term "hypopharyngeal eminence" is derived from the Greek words "hypo" meaning "under", "pharynx" meaning "throat", and "eminence" meaning "projection". Thus, the term can be translated as "projection under the throat".

Development[edit | edit source]

The hypopharyngeal eminence develops during the fourth week of embryonic development. It is formed from the third and fourth pharyngeal arches, which are structures that form in the embryonic pharynx. The third pharyngeal arch contributes to the formation of the stylopharyngeus muscle, while the fourth pharyngeal arch contributes to the formation of the thyrohyoid muscle and the cricothyroid muscle.

Function[edit | edit source]

The hypopharyngeal eminence plays a crucial role in the development of the larynx. It gives rise to the arytenoid cartilages, the cricoid cartilage, and the thyroid cartilage. These structures are essential for the function of the larynx, which is involved in breathing, sound production, and protection of the trachea from food aspiration.
