1Where is Wangu?

Upper side of the neck, in the hollow behind and below the mastoid process.

Beneath the point

Temporal bone · Sternocleidomastoid muscle · Splenius capitis muscle · Longissimus capitis muscle

Our 3D measurement · In our 3D model: skin at the height of the mastoid tip, 2 mm behind the posterior border of the mastoid process (8.5 mm behind the tip).

2How do I find it on my body?

Feel the hard bony bump behind the earlobe (the mastoid process).
Slide a fingertip off its tip, backward and downward.
Press the hollow that forms behind and below it.

📖 Words explained

longissimus capitis: The top part of longissimus. It runs from the upper back and lower neck bones to the mastoid process behind the ear, and tips and turns the head.
splenius capitis: A flat, strap-like muscle at the back of the neck, under trapezius. It slants up from the lower neck and upper back bones to the mastoid process and back of the skull, and tips and turns the head.
mastoid process: The bone sticking down just behind the earlobe. It is part of the temporal bone, and sternocleidomastoid attaches to it.
temporal bone: The skull bone on the side of the head around the ear. The ear canal and the bump behind the ear (mastoid process) are on it, and it forms the jaw joint with the mandible.
sternocleidomastoid: The thick muscle slanting across the side of the neck. It runs from the mastoid process behind the ear down to the breastbone and collarbone, and stands out as a thick cord when you turn your head to the other side.
