The dorsalis pedis artery runs beneath it.

It is on the top of the foot.

Beneath the point

Dorsalis pedis artery · Tendon of extensor digitorum longus · Second metatarsal bone · Intermediate cuneiform bone

Our 3D measurement · In our 3D model: skin on top of the foot over the joint between the base of the second metatarsal and the intermediate cuneiform; 6.2 mm horizontally from the dorsalis pedis artery.

2How do I find it on my body?

From ST41, follow the top of the foot down toward the second toe.
Trace the second metatarsal back toward the ankle.
Press where the bone ends at a joint, meeting the intermediate cuneiform.

A cun is a body-scaled unit of length. The precise way is to divide a bone length into equal parts (proportional bone cun); finger widths are a quick estimate.

📖 Words explained

tendon of extensor digitorum longus: The four strands the extensor digitorum longus splits into on the top of the foot. Lift your toes and they stand out like cords.
intermediate cuneiform: The middle and smallest of the three wedge-shaped ankle bones. The second metatarsal joins it.
dorsalis pedis artery: The artery that runs from the front of the ankle onto the top of the foot. You can feel its pulse at the highest point of the foot, just outside the big-toe tendon.
