Core Course Performance Objectives (CCPOs):
  1. Describe the anatomic structures of the head and neck. (CCC 1, 2, 4, 5, 6; PGC 1, 5)
  2. Relate the anatomy of the head and neck to patient assessment and care. (CCC 1, 2, 4, 5, 6; PGC 1, 5)

See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

Measurable Performance Objectives (MPOs):

  1. Describe the anatomic structures of the head and neck.
    1. Describe the following structures, their location, and their functions.
      1. Cranial and facial bones and their landmarks (i.e., foramina, canals, fossae, processes, sutures, and/or sinus cavities)
      2. Muscles of facial expression, mastication, tongue, and soft palate
      3. Temporomandibular joint and its specific components
      4. Nerves (i.e., trigeminal, facial, glossopharyngeal, vagus, and hypoglossal)
      5. Arteries (branches of the carotid artery) and veins (branches that drain into the internal and external jugular veins)
      6. Lymph nodes
    2. Identify the structures listed above on a model, diagram, image, and/or life form.
  2. Relate the anatomy of the head and neck to patient assessment and care.
    1. Relate knowledge of the muscles, the temporomandibular joint (TMJ), and the lymph nodes in the patient assessment process.
    2. Identify the nerves that must be anesthetized to complete dental hygiene procedures.
    3. Relate the spread of dental infection to the lymphatic, venous, and sinus pathways.
Evaluation Criteria/Policies:
