Superior nuchal line

Linea nuchae superior

How to find it
First find the external occipital protuberance in the midline of the occiput and sweep laterally from it, towards the mastoid process. You then follow a faint bony ridge; have the head press gently back against your hand and trapezius tightens beneath it.
What you use it for
Attachment of trapezius, sternocleidomastoid and splenius capitis. The whole line is tender in cervicogenic headache and with prolonged forward head posture.
