Terminology• Distal – Further away from the core of the body.• Proximal – Closer to the core of the body.• Lateral- Away from the midline of the body, peripherally. • Medial- Towards the midline of the body.• Anterior- In the front of the body.• Posterior- The back of the body.• Superficial – Closer to the surface of the body (skin)• Deep- Towards the inside of the body. (Bones)• Plantar- The bottom aspect of foot. (The sole)• Dorsal- The top surface an anatomical part, usually the foot. Can be
the back of a person when lying in the prone position. (Dorsal Fin).• Eversion – Moving away from the midline of the body.• Inversion – Moving towards the midline of the body.
