A member asked:

Where exactly is the mastoid bone at in your body and what is it's purpose?

A doctor has provided 1 answer

See below: The mastoid process is behind your ear near the lower, back part of your skull. Its purpose is for attachment of facial muscles, primarily those for chewing (mastication), as well as the sternocleidomastoid muscles in your neck.

Hi there, had a quick question I noticed my left mastoid bone is bigger than my right, I randomly found this out. No pain, both sides have this weird muscle that if I press on moves, but the left (muscle I think) is bigger. Is this something to worry?
