Exam Question
Anterior triangles of neck are-Submental, Digastric, Carotid, Muscular.
Submental lymph nodes drain superficial tissues beliw tge chin, central part of lower lip, adjoining gums, anterior part if floor of mouth & tip of tongue.
On both sides submental triangle is bounded by Anterior belly of diagastric.
Posterior boundary of carotid triangle is formed by anterior border of sternocleidomastoid.
Hypoglossal nerve is a content of both digastric & carotid triangles.
Structure superficial to mylohyoid in anterior digastric triangle is Mylohyoid artery & nerve
Floor of digastric triangle is formed by mylohyoid (anteriorly) & hyoglossus (posteriorly)
Infrahyoid ribbon muscles are the chief contents of muscular triangle.
Don’t Forget to Solve all the previous Year Question asked on Anterior triangle of neck
Submental triangle is bounded by anterior belly of digastric (laterally), midline of the neck b/w the mandible & the hyoid bone (medially) & base of hyoid bone.
Mylohyoid muscle is at the floor & submental lymph nodes are the content.
