Main muscles of the head and neck
After completing this study unit you will be able to:
- Learn the major groups of the muscles of the head and neck.
- Understand the anatomical relationships between those muscles.
According to their functions, the muscles of the head are divided into two main groups; muscles of facial expression and muscles of mastication. The former allow us to express our feelings by producing a myriad of facial expressions, while the latter act on the temporomandibular joint to allow us to chew food.
The muscles of the neck, however, are divided by their location relative to the vertebral column. They are distributed into three compartments; the anterior, lateral and posterior. These muscles produce the movements of the cervical spine (neck) and allow our head to move in various directions.
This video tutorial will introduce you to the main muscles of the head and neck and prepare you for the next steps in your learning path of this topic.
