Directional Terms
- Anterior refers to the front of the body
- Posterior refers to the back of the body
- Deep refers to a location closer to the center of the body
- Superficial refers to a location closer to the surface of the body
- Ipsilateral refers to the same side of the body
- Contralateral refers to the opposite side of the body
- Unilateral refers to one side of the body
- Bilateral refers to both sides of the body
Applying Directional Terms to Body Structures
- Thorax and Abdomen: anterior and posterior regions
- Wrist and Shoulder: proximal and distal regions
- Nose and Ears: anterior and lateral regions
- Skin and Muscles: superficial and deep layers
- Lungs and Heart: anterior and posterior regions
- Radius and Ulnar: proximal and distal regions
- Right thumb and left big toe: contralateral and ipsilateral regions
- Left upper limb and left lower limb: ipsilateral regions
- Right and left kidneys: bilateral regions
- Right and left legs: bilateral regions
Body Parts and Structures
- Cardiac refers to the heart
- Gastric refers to the stomach
- Cutaneous refers to the skin
- Gluteal refers to the buttock
