Superior / Cranial / Cephalic
Inferior / Caudal
Medial / Lateral
Proximal
Toward the center
Distal
Away from the center
Examples of proximal / Distal
Extremities: elbow is distal to shoulder / elbow is proximal to wrist
GI Tract: proximal is close to mouth / stomach is proximal to intestines / distal would be anus
Circulatory System: Proximal close to heart
Vessels near heart are proximal to vessels in fingers
Superficial
Toward the skin
Deep
Internal or away from skin
Hypo
Below
