16. Regions of the Neck
 Anterior Triangle
-bounded by sternohyoid muscle, the
digastric muscle, and the sternomastoid
muscle.
 Posterior Triangle
- bounded by the cleidomastoid muscle,
the clavotrapezius muscle, and the clavicle.

17. Anterior Triangle
 Thyroid Gland
-bilobate
-endocrine gland
 Common Carotid Arteries and Branches
- cranial thyroid artery
- muscular branch (lateral to the CTA)
- cranial laryngeal artery
- lingual artery (sublingual artery)
- internal (brain) and external carotid arteries (passes deep
to the digastric muscle

18. Posterior Triangle
 The EXTERNAL JUGULAR VEIN runs obliquely
across this triangle.
 The SPINAL ACCESSORY NERVE runs from
the cleidomastoid and clavotrapezius. This
nerve is the only structure found in both
triangles.
 The SUBCLAVIAN ARTERY and VEIN are
found deep to the clavicle.
