Superficial Structures of Neck 1. Define the anatomical terminologies pertaining to the neck 1. Obviously if there is an anatomical term throughout the outline that is confusing for you look it up. :)
Superficial Structures of Neck 2. Define the laryngeal prominence, jugular notch and the clinical significance of the supraclavicular fossa. 2. Laryngeal prominence is- an enlarged portion of the thyroid cartilage. AKA Adam’s apple. Jugular notch is- T2 a rounded depression superior to Mandible. Supraclavicular fossa is- The pressure point for subclavian artery
Superficial Structures of Neck 3. Describe clinical manifestations of: lesions involving the mandibular and cervical branches of cranial nerve (CN) VII, the facial nerve. 3. The cervical innervates the platysma and would cause drooping of the skin around the chin The mandibular branch serves the risorius muscle. A lesion would cause the sides of the mouth to droop.

Superficial Structures of Neck To get a better understanding (visual) of the Triangles in the neck refer to: page 1054 in Moore (5th edition)
Superficial Structures of Neck 6.23 Are the 5 branches of the external carotid artery contained in the Carotid Triangle 6.23 Yes, the beginning parts of those five branches (Dr. Thomas email response to this question)
Superficial Structures of Neck 5.2 Explain the other form of Congenital Torticollis: Fibromatosis torticollis (colli) 5.2 Fibrous (inflammation)tissue develops in SCM while in uterus. This type is NOT treated with manual therapy like the congenital torticollis from a difficult birth is treated.

Superficial Structures of Neck 5.4 Explain Aquired Torticollis: spasmodic torticollis 5.4 Develops in Adults due to Tonic (continuous) or Clonic (intermittent) spasms of 1 SCM. At times, the trapezius on the affected side may also develop spasms.
