Carotid triangle
Trigonum caroticum
- Latin synonym: Fossa carotica
Definition
The carotid triangle is a bilateral anatomical region of the neck, defined by specific boundaries: it is bounded superiorly by the posterior belly of the digastric muscle, laterally by the anterior border of the sternocleidomastoid muscle, and inferiorly by the superior belly of the omohyoid muscle.
Within this triangle are essential vascular and neural structures, primarily the bifurcation of the common carotid artery into the internal and external carotid arteries, as well as branches of the external carotid artery and portions of the internal jugular vein and the cranial nerves.
