Superior direction

refers to a position that is above or higher than another part of the body. For example, the head is superior to the neck.

Inferior direction

refers to a position that is below or lower than another part of the body. For example, the stomach is inferior to the heart.

Lateral direction

refers to a position that is farther from the midline of the body. For example, the arms are lateral to the chest.

medial direction

refers to a position that is closer to the midline of the body. For example, the nose is medial to the eyes.

Anterior direction

refers to a position that is towards the front of the body. For example, the chest is anterior to the back.

Posterior direction

refers to a position that is towards the back of the body. For example, the spine is posterior to the chest.

Distal direction

refers to a position that is farther away from the point of attachment or trunk of the body. For example, the fingers are distal to the wrist.

Lateral direction

refers to a position that is away from the midline of the body. For example, the arms are lateral to the chest.

Medial direction

refers to a position that is closer to the midline of the body. For example, the nose is medial to the cheeks.

Superficial direction

refers to a position that is closer to the surface of the body. For example, the skin is superficial to the muscles.

Deep direction

Furthest from the outer surface
