–Armrefers only to the UE between the shoulder and elbow–two Lower Extremities (LE) consist of regions:–femoral region (thigh), popliteal (posterior knee), crural (lower leg), tarsal (ankle), pedal (foot), digits (toes)–Legrefers only to the LE between the knee and the ankle

Cranial Cavity & Vertebral Canal•cranial cavity–contains the brain–lined with meninges•vertebral canal–enclosed by the vertebral column–contains the spinal cord–lined with meninges
The Major Body Cavities
Thoracic Cavity•the thoracic cavity is divided into subdivisions by a thick tissue called the mediastinum•mediastinumis the region between the lungs extending from the base of the neck to the diaphragmand contains viscera–heart, major blood vessels, esophagus, trachea, thymus•mediastinumdivides the thoracic cavity into 2 pleural cavities (lungs) and 1 pericardial cavity(heart)
Thoracic Cavity•Pericardium– two-layered membrane around the heart–inner visceralpericardium–outer parietalpericardium–pericardial cavity between–pericardial fluid•Pleura– membrane(secretes fluid) around the lungs–inner visceralpleura–outer parietalpleura–pleural cavity between–pleural fluid
Abdominopelvic Cavity•brim of pelvis separates the abdominal and pelvic cavities–abdominal cavity contains most of our digestive organs, and our kidneys and ureters–pelvic cavity contains rectum, urinary bladder, urethra, and reproductive organs•peritoneum – two-layered serous membrane in the abdominopelvic cavity–inner visceralperitoneum–outerparietal peritoneum–peritoneal cavity between layers–peritoneal fluid
Abdominal Cavity•retroperitoneal: some of the organs in the abdominal cavity are located betweenthe peritoneum and dorsal body wall•therefore, these organs are classified as not being inside the peritoneal cavity – they are behind the peritoneum retroperitoneal•adrenal glands, kidneys, urinary bladder, pancreas, and others
