Explanation:

• In anatomy, anterior means front - facing and posterior means back - facing. The trachea is in front of the esophagus, the heel is behind the toes, the heart is in front of the backbone, the breastbone is in front of the shoulder blade, and the esophagus is behind the larynx.
• Ventral refers to the front or belly - side and dorsal refers to the back.
• Medial means towards the mid - line of the body and lateral means away from the mid - line.
• Proximal means closer to the origin or attachment point and distal means further away.
• Superficial is closer to the surface of the body, deep is further from the surface, peripheral is away from the center, and central is towards the center.
