DHYG 2400 - Head, Neck, and Oral Anatomy/Physiology

This course focuses on the structure and function of the head and neck of the human body, including the nomenclature of bones, muscles, blood vessels, nerves, glands, lymphatic structure, fasciae, and spaces.  Emphasis is placed on structures associated with the mouth and the masticatory system and their clinical application to the dental hygiene process of care.   

Credits: 2

Instructional Method Lecture


Admission to the Dental Hygiene program required.



Minimum Student Competencies
Upon completion of DHYG 2400 Head, Neck, and Oral Anatomy and Physiology, the student will:

  1. Locate on diagrams and models of the head and neck all of the major components of the skeletal, muscular, glandular, nervous, vascular, and lymphatic systems and describe their physiological importance to the practice of dental hygiene.
  2. Recognize the relationship of the oral cavity and head and neck region to the rest of the body.
  3. Identify all intra-and extra-oral landmarks associated with the major anatomical structures in the head and neck region.
  4. Describe the paranasal sinuses, their drainage, relationship to structures in the oral cavity and spread of dental infection in the head and neck.
  5. Describe functions of masticatory and facial expression musculature.
  6. Relate this anatomy to the signs and symptoms of temporomandibular joint dysfunction.
  7. Identify lymphatic drainage from the head and neck and relate it to the spread of infection and metastasis.
  8. Describe the major fascial spaces and compartments and relate them to the spread of infection in the head and neck.
  9. Distinguish between veins and arteries and their functions.
  10. Recognize nerves of the head and neck region and their paths of innervation.
  11. Identify landmarks for local anesthesia on a human skull.
