Course Description

Studies the structures and functions of oral anatomy with emphasis on those structures important in the administration of local anesthesia.

Intended Outcomes for the course

Students will describe the structures and functions of the tissues and organs of the head and neck region.

Outcome Assessment Strategies

  • In class and on examinations, identify anatomic structures of the head and neck.

  • Shown anatomic structures in class and on exams, identify their functions and relationship to dental hygiene practice.

  • Shown anatomic landmarks, relate them to local anesthesia use.

  • Weekly quizzes and a comprehensive final exam

Course Content (Themes, Concepts, Issues and Skills)

  • Anatomy of the head and neck: bones, nerves, muscles, vessels, lymphatic and facial spaces.

  • Features of pain recognition.

  • Treatment considerations in and around the oral cavity

  • The trigeminal nerve and its branches.


  1. Identify the anatomic features of the head and neck that serve as landmarks for the dental injection of local anesthetics.

  2. Identify the branches of the trigeminal nerve and areas of the head and neck served.

  3. Relate the branches of the facial nerve involved in mastication.

  4. Identify the muscles of the head and neck involved in mastication and swallowing.

  5. Identify the vessels of the head and neck that are near areas of local anesthesia injection sites.

  6. Identify vessels that serve all areas of the oral cavity and surrounding structures.

  7. Describe the location of the bones of the skull that serve as muscle attachments and insertions for the muscles of mastication.

  8. Explain the lymphatic drainage and facial spaces involved in the spread of infection from the teeth to the structures of the head, neck and thorax.

  9. Identify the sinuses and the drainages into the oral cavity.

  10. Describe the anatomic features of the temporomandibular joint and their relationship to TMJ dysfunction.

  11. Compare the characteristics of deep, superficial, neurogenic and muscular pain and describe the neurophysiology of impulse transmission.
