What Do Distal and Proximal Mean?

Distal means farthest away, and proximal means closest to. In the picture, the left side of the wound (represented as being closed with duct tape) is distal to the heart, and the right side is proximal to the heart.

by James Hubbard, M.D., M.P.H.

In medical terminology, distal and proximal, or distally and proximally, describe anatomical locations.

Proximal means closest to, and distal means farthest away.

With reference to a wound on an arm, distal to the wound would be past the wound toward the fingers. Proximal to the wound would be from the wound toward the shoulder.

On the leg, the toes are the most distal, the hip the most proximal.

The knee is proximal to the ankle; the elbow is proximal to the wrist. Get it?

With reference to blood vessels, distal would be furthest from the heart. Proximal closest.

If it’s not clear, please ask in the comments section below.

    Hi, I’m a first term Dental student and I missed my first anatomy session :(. So what I understand so far is that for example: The elbow is proximal to the wrist= the elbow is closer (to the trunk) than the wrist. Is this right? I am seriously freaking out over this.

      Hey, you’ll get it. And, yes, the elbow is proximal to the wrist.

        Oh thank you thank you thank you! I think I got it!

    While deep-sea fishing, Shamara accidentally hooked herself. Her injury is on the anterior surface (front of the body), superior to her foot (above her foot), inferior to her hip (below her hip), distal to her ankle (farther from the origin of the body part or point of attachment; farther away from the body), and proximal to her hip (closer to the origin of the body part or point of attachment; closer to the body)

  • whatever

    Thanks

    These two terms are used to define the relevance and proximity of the wound and heart. For example proximal is always between the wound and heart while distal is going to be after the heart and wound

    • R3D3Y3K1K1

      To refine distal is on the furthest side of the wound from the heart while proximal is on the closer side of the wound to the heart

        Thanks.

    When discussing cross clamping of the aorta for example above the aortic valve, but below the innominate artery, is the innominate artery proximal or distal to the clamp? Thank you

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      Unless there’s something I don’t know about how a surgeon would orient that, I would think the innominate artery would be distal to the clamp.

    on what basis are the proximal convoluted tubule and the distal convoluted tubule named so? i mean, both seem to be on the same position, so what is the reference point?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      I assume it’s proximal distal to the junction with the artery, but that’s just a guess.

    Your foot is what to your hip

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      Your foot is distal to your hip.

  • http://www.jakeshomeworkouts.com/ Jake Long

    This one has been confusing for me. But I think I get it. So is it always in relation to the heart, or the middle of the body?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      Yes.

  • Christy Detrick

    does it mean going up toward the body is proximal, and going down is distal?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      Yes.

  • susan

    if the point of attachment is the coxal(hip) how is the knee distal to the foot?
    If the point of attachment is the deltoid (shoulder) how is the anticubital(anterior of elbow) proximal the hand ?
