Study Notes
- The neck has two main areas: anterior and posterior triangles.
- The anterior triangle is formed by mandible, sternocleidomastoid, and midline of the neck.
- It has four subdivisions: carotid, muscular, submandibular, and submental triangles.
- Carotid triangle contains common carotid artery, internal jugular vein, and cranial nerves X & XII.
- Muscular triangle contains infrahyoid muscles, pharynx, and thyroid gland.
- Submandibular triangle contains submandibular salivary glands, lymph nodes, facial artery, and vein.
- Submental triangle contains submental lymph nodes.
- The posterior triangle is formed by trapezius, sternocleidomastoid, and clavicle.
- It has two subdivisions: occipital and subclavian triangles.
- Occipital triangle contains vertebral muscles, cervical plexus, brachial plexus, accessory nerve, and external jugular vein.
