Nearly everyone has had a headache at some point. Each year, 95 percent of women and nearly 90 percent of men will have a headache, reports Harvard Medical School. There are many different types of headaches, and surprisingly, the pain can sometimes originate in the jaw muscles. How are jaw muscles connected to a headache, and what can you do about it?
The Temporalis Muscle
The temporalis muscle, also called the temporal muscle, is one of the four main muscles involved with chewing, explains the Journal of Oral Research. The other chewing muscles are the masseter, medial pterygoid and lateral pterygoid. (Teach Me Anatomy lays out a diagram of these muscles and their placement around your jaws.)
The temporal muscle connects the side of the skull to the lower jawbone, and it helps you close your jaw, explains The Anatomical Basis of Dentistry. It also helps you shift your lower jawbone to the left and right.
