1 Clinical terminology based on a Greek or Latin root word. Common Regional NamesClinical terminology based on a Greek or Latin root word.
2 Planes and SectionsA plane is an imaginary flat surface that passes through the body.A section is one of the 2 surfaces (pieces) that results when the body is cut by a plane passing through it.
3 Sagittal Plane Sagittal plane Midsagittal plane Parasagittal plane divides the body or an organ into left and right sidesMidsagittal planeproduces equal halvesParasagittal planeproduces unequal halves
4 Other Planes and Sections Frontal or coronal planedivides the body or an organ into front (anterior) and back (posterior) portionsTransverse(cross-sectional) or horizontal planedivides the body or an organ into upper (superior) or lower (inferior) portionsOblique planesome combination of 2 other planes
5 Planes and Sections of the Brain (3-D anatomical relationships revealed) Horizontal PlaneFrontal PlaneMidsagittal Plane
7 Superior or Inferior Superior Inferior towards the head The eyes are superior to the mouth.Inferioraway from the headThe stomach is inferior to the heart.
8 Dorsal or Ventral Dorsal or Posterior Ventral or Anterior at the back of the bodyThe brain is posterior to the forehead.Ventral or Anteriorat the front of the bodyThe sternum is anterior to the heart.
9 Medial or Lateral Medial Lateral nearer to the midline of the body The heart lies medial to the lungs.Lateralfarther from the midline of the bodyThe thumb is on the lateral side of the hand.
10 Proximal or Distal Proximal nearer to the attachment of the limb to the trunkThe knee is proximal to the ankle.Distalfarther from the attachment of the limb to the trunkThe wrist is distal to the elbow.
12 Abdominopelvic Cavity Inferior portion of ventral body cavity below diaphragmEncircled by abdominal wall, bones & muscles of pelvis
13 Thoracic CavityEncircled by ribs, sternum, vertebral column and muscleDivided into 2 pleural cavities by mediastinumMediastinum contains all thoracic organs except lungs
14 MediastinumMidline wall of tissue that contains heart and great vessels, esophagus, trachea and thymus.
15 Serous MembranesThin slippery membrane lines body cavities not open to the outsideparietal layer lines walls of cavitiesvisceral layer covers viscera within the cavitiesSerous fluid reduces friction
