Superior or cranial toward the head end of the body; upper (example, the hand is part of the superior extremity). Inferior or caudal away from the head; lower (example, the foot is part of the inferior extremity). Anterior or ventral front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal back (example, the shoulder blades are located on the posterior side of the body). Medial toward the midline of the body (example, the middle toe is located at the medial side of the foot). Lateral away from the midline of the body (example, the little toe is located at the lateral side of the foot). Proximal toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone). Distal away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm). Body Cavities peritoneum Mediastinum subdivided into • superior • inferior superior mediastinum (1) anterior mediastinum (2) medial mediastinum (3) posterior mediastinum (4) – Anterior • anterior boundary is the back of the sternum. • Its posterior boundary is the pericardium of the heart. – Middle paricardial cavity – Posterior • anterior boundary is the posterior pericardial wall. • The posterior boundary is the anterior surfaces of the bodies of thoracic vertebrae T5T12. superior mediastinum (1) anterior mediastinum (2) medial mediastinum (3) posterior mediastinum (4) anterior mediastinum (1) middle mediastinum (2) posterior mediastinum (3) Anatomical Position Pronation Supination Adduction Abduction Neutral (adduction) Flexion Neutral Extension Neutral Opposition Adduction Abduction Lateral Medial Inversion Neutral Eversion Superior Axial (Transverse) sections Inferior Median Plane (Saggital ) Coronal Plane Anterior Posterior Hip Shoulder Flexion Hip flexion Extension Extension Flexion Extension Knee Elbow
