It is so called because it contains all the three carotid arteries, viz. common carotid, internal carotid, and external carotid. Boundaries ------------------- Superiorly: Posterior belly of digastric supplemented by stylohyoid. Anteroinferiorly: Superior belly of omohyoid. Posteriorly: Anterior border of sternocleidomastoid. Roof: It is formed by investing layer of deep cervical fascia. The superficial fascia over the roof contains platysma, cervical branch floor: thyrohyoid, hyoglossus, middle and inferior pharyngeal constrictors roof: skin, superficial fascia, platysma, deep fascia of facial nerve and transverse cervical nerve (a cutaneous branch of the cervical plexus). Floor: It is formed by the following four muscles: 1. Thyrohyoid. 2. Hyoglossus. 3. Middle constrictor. 4. Inferior constrictor. Contents --------------- 1. Carotid arteries (a) Common carotid artery (b) Internal carotid artery (c) External carotid artery and its first five branches. 2. Carotid sinus and carotid body. 3. Internal jugular vein. 4. Last three cranial nerves (a) Vagus nerve (b) Spinal accessory nerve (c) Hypoglossal nerve. 5. Carotid sheath 6. Ansa cervicalis. 7. Cervical part of the sympathetic chain. 8. Deep cervical lymph nodes. Important vascular structures are found within this triangle. It contains the bifurcation of the common carotid artery into internal and external carotid arteries. The internal carotid artery initially lies postero-laterally to the external carotid artery. It then becomes posterior to it. Branches of the external carotid artery are found in the triangle including: superior thyroid artery lingual artery facial artery occipital artery ascending pharyngeal artery Corresponding veins to these branches drain into the internal jugular vein. Crossing both the internal and external carotid artery is the hypoglossal nerve. Nerves ----------- hypoglossal nerve nerve to thyrohyoid from the C1 ventral ramus of the cervical plexus superior root of ansa cervicalis internal laryngeal nerve external laryngeal nerve #anatomy #carotidtriangle #anatomyofcarotidtriangle #carotidtrangleanatomy #animatedanatomyvideos #usmleanatomyvideos #mbbs #neetpg #smartmedlearn ---------------------------------------------------------------------------------------------------------------- To watch more videos, please click here:- UInar nerve in Hindi/Anatomy/Simplified - Course, relations & branches/ Guyon's canal Cubital Tunnel    • UInar nerve/Anatomy/Simplified - Course, r...   Erb's paralysis in Hindi/Brachial Plexus Injury    • Erb's paralysis/Brachial Plexus Injury/Erb...   Brachial plexus in Hindi- Roots, Trunks, Divisions, Cords and Branches    • Brachial plexus / Anatomy / Simplified - R...   Cubital fossa (Boundaries, contents, and clinical anatomy) in Hindi    • Cubital fossa / Anatomy/Simplified - Bound...   Light reflex pathway and lesions in Hindi (Part-2/2)    • Light reflex pathway and lesions (Part-2/2...   Light reflex pathway and lesions in Hindi (Part-1/2) // pupillary light reflex pathway    • Light reflex pathway and lesions (Part-1/2...   Visual Pathway and Lesions (Part-2/2) in Hindi / Optic nerve pathway / Visual field defects    • Visual Pathway and Lesions (Part-2/2) in H...   Visual Pathway and Lesions (Part-1/2) in Hindi    • Visual Pathway and Lesions (Part-1/2) in H...   Cerebrum (Part-3/6) in Hindi - Gyri & Sulci on Medial and Inferior surface of cerebral hemisphere    • Cerebrum (Part-3/6) in Hindi - Gyri & Sulc...   Cerebrum (Part-2/6) in Hindi - Gyri & Sulci on Superolateral surface of cerebral hemisphere, Insula    • Cerebrum (Part-2/6) in Hindi - Gyri & Sulc...   Cerebrum (Part-1/6) in Hindi - External Features (Poles, Surfaces, Borders & Lobes)    • Cerebrum (Part-1/6) in Hindi-External Feat...   Bell's Palsy (Hindi)/ Facial Palsy/ Upper and Lower Motor Neuron Facial Palsy    • Bell's Palsy (Hindi)/ Facial Palsy/ Upper ...   Bell's Palsy (English)    • Bell's palsy/ Upper and Lower motor neuron...   Facial Nerve - Functional Components, Course & Branches    • Facial Nerve - Functional Components, Cour...   Deep Cervical fascia - II (Pretracheal & Prevertebral Layer)    • Deep Cervical fascia - II (Pretracheal & P...   Deep Cervical Fascia - I (Investing Layer)    • Deep Cervical Fascia - I (Investing Layer)...   Thank you Smart Med Learn Dr. Ankit Jain MBBS, MS
