SuperiorTowards the head, or above another part. The heart is superior to the stomach. Also called cranial.
InferiorAway from the head, or below another part. The knee is inferior to the hip. Also called caudal.
MedialTowards the midline of the body. The nose is medial to the eyes.
LateralAway from the midline, towards the side. The ears are lateral to the eyes.
ProximalOn a limb, nearer to where it joins the trunk. The elbow is proximal to the wrist.
DistalOn a limb, farther from where it joins the trunk. The fingers are distal to the wrist.
Front, back, surface: 4 4
AnteriorTowards the front of the body. The breastbone is anterior to the spine. Also called ventral.
PosteriorTowards the back of the body. The spine is posterior to the heart. Also called dorsal.
SuperficialNearer the surface of the body. The skin is superficial to the muscles.
DeepFarther from the surface of the body. The bone is deep to the muscles.

How it works
These are the directional terms of anatomy, each drawn as an arrow: six on a body in the anatomical position from the front, two on the body from the side, and two on a thigh cut across.

Three pairs on the front view
Superior points up towards the head and inferior down towards the feet. Medial points towards the body's midline and lateral away from it. On a limb, proximal points towards the trunk and distal away from it.
Two more pairs
From the side, anterior points to the front and posterior to the back. In the thigh cut across, superficial points out towards the skin and deep points in towards the bone.
Every term compares two places, so it needs a 'than': the knee is proximal to the ankle, but distal to the hip.
Questions and answers
What is the anatomical position?
Standing upright facing forward, feet together, arms at the sides with the palms facing forward. Directional terms always describe the body in this position.
What is the difference between proximal and distal?
Both are used on limbs. Proximal means nearer to where the limb joins the trunk; distal means farther from it. The elbow is proximal to the wrist.
What do anterior and posterior mean?
Anterior means towards the front of the body and posterior towards the back. They are also called ventral and dorsal.
