Body Cavities & Memb
Body Cavities and Membranes
| Question | Answer |
|---|---|
| Pericardial Membranes | Parietal pericardium, visceral pericardium, pericardial cavity |
| (Skeleton) Axial | head, neck, and trunk |
| (Skeleton) Appendicular | upper and lower limbs |
| Body Cavities | Spaces within the body that contain internal organs |
| Two principal body cavities | dorsal and ventral cavity |
| Dorsal Body Cavity | located near the posterior/dorsal (back) surface of the body |
| What is the dorsal body cavity composed of? | composed of cranial cavity(contains the brain), vertebral/spinal canal (contains the spinal cord and surrounded by sections of the backbone) |
| Ventral Body Cavity | located on the anterior/ventral (belly) side of the body; contains the organs called viscera |
| Two subdivisions of the ventral body cavity | thoracic cavity and abdominopelvic cavity, separated by the diaphragm |
| The Thoracic Cavity | pleural cavities, pericardial cavity, the mediastinum |
| Pleural cavities | right and left: contain the lungs |
| Pericardial cavity | around the heart |
| The Mediastinum | region between the lungs, includes the heart, esophagus, trachea and thymus gland |
| Abodominopelvic cavity | abdominal and pelvic cavity |
| Upper Abdominal Cavity | contains the stomach, liver, spleen, gallbladder and the small and large intestines |
| Lower Pelvic Cavity | enclosed by the pelvic bones, terminal end of the large intestines, urinary bladder, and internal reproductive organs |
| Oral Cavity | teeth and tongue |
| Nasal Cavity | sphenoidal and frontal sinuses |
| Orbital Cavities | eyes |
| Middle Ear Cavities | middle ear bones |
| Serous Membranes | thin, double layered membranes; lines the walls of cavities and folds back to cover the organs; secretes a lubricating fluid called serous fluid |
| Parietal Membranes | line cavities |
| Visceral Membranes | cover organs |
| Pleural Membranes | deals with the lungs |
| Pericardial Membranes | deals with the heart |
| Peritoneal Membranes | deals with the abdominopelvic cavity |
| Pleural Membranes | Parietal pleura, visceral pleura, pleural cavity |
| Peritoneal Membranes | Parietal peritoneum, visceral peritoneum, peritoneal cavity |
| Parietal pleura | line the walls of the right and left thoracic cavities (lungs) |
| Visceral pleura | membranes that cover the lungs |
| Pleural cavity | located between the parietal and visceral pleural membranes |
| Parietal pericardium | lines the pericardial cavity (heart) |
| Visceral pericardium (epicardium) | covers the heart surface |
| Pericardial cavity | located between the parietal and visceral pericardial membranes |
| Parietal peritoneum | lines the abdominal wall |
| Visceral peritoneum | covers each organ |
| Peritoneal cavity | the space between these membranes |
