HHP 1150 Unit 1
Body Cavities, Serous Membranes
| Question | Answer |
|---|---|
| body cavity | separate enclosed space within body that houses organs |
| body cavity organization | Dorsal (cranial and spinal), Ventral (thoracic 3, abdominopelvic 2) 3- pleural, mediastinum/mediastinal, pericardial 2- abdominal, pelvic |
| dorsal cavity | posterior |
| ventral cavity | anterior, separated by diaphragm |
| Describe cranial cavity | dorsal cavity. contains brain |
| Describe vertebral canal | dorsal cavity. contains nerves and spinal cord |
| where is thoracic cavity in the ventral cavity? What cavities does it contain? | ventral , superior to diaphragm. pleural, mediastinum (mediastinal), pericardial |
| where is the abdominopelvic cavity in the ventral cavity? What cavities does it contain? | ventral, inferior to diaphragm, abdominal, pelvic |
| Describe the pleural cavities | ventral, thoracic, one cavity surrounding each lung. |
| Describe pericardial cavity | ventral, thoracic, one cavity surrounding heart |
| Describe mediastinum/mediastinal cavity | ventral, thoracic, one cavity intermediate to lung |
| What separates the two abdominopelvic cavities? | pelvic brim of hip bones |
| Describe abdominal cavity | ventral, abdominopelvic, one cavity containing digestive organs |
| Describe pelvic cavity | ventral, abdominopelvic, one cavity surround pubic and some urinary organs |
| serous membrane: What is it? Where are they found? Why are they significant? | double layered continuous membrane. Found lining VENTRAL cavities |
| Term: parietal | lining internal surface of body wall (most superficial layer) |
| Term: visceral | lines external surface of specific organ (most deep layer touching organ wall) |
| Term: pleural | lungs |
| Term: pericardial | heart |
| Term: peritoneum | walls of abdomin |
| serous cavity: What is it? Where are they found? Why are they signifigant? | space between parietal and visceral serous layers filled with serous fluid. Reduces friction between moving organs |
| membranes of thoracic cavity: pericardium | parietal pericardium, visceral pericardium, pericardial cavity |
| membranes of thoracic cavity: pleura | parietal pleura, visceral pleura, pleural cavity |
| membranes of thoracic cavity: peritoneum | parietal peritoneum, visceral peritoneum, peritoneal cavity |
| The fluid inside a ventral serous membrane cavity is named: Ex: pericardial fluid inside pericardial cavity | after the cavity it is in |
