| Question | Answer |
|---|---|
| How many regions do doctors mentally divide the abdomen into? | nine |
| Name the nine regions of the abdomen | right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, left iliac |
| How many regions do doctors mentally divide the abdomen into? | nine |
| Name the nine regions of the abdomen | right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, left iliac |
| Simple way of mentally dividing the abdomen | 4ths (quadrants) |
| Name the quadrants of the abdomen | right upper, left upper, right lower, left lower |
| Name the two functions of body cavities | protect the organs they contain, keep organs in a fairly consistent location |
| Name the two principal body cavities | dorsal, ventral |
| Name the subdivisions of the dorsal body cavity | cranial cavity and spinal canal |
| The opening that interconnects the cranial cavity and spinal canal | foramen magnum |
| Name the subdivisions of the ventral body cavity | thoracic cavity, abdominal cavity, pelvic cavity |
| Mass of tissue between the lungs extending from the sternum to the vertebral column | mediastinum |
| Cavity that encloses the heart | pericardial cavity |
| Cavities that each contain a lung | pleural cavities |
| boundary between the thoracic and abdominal cavity | muscular diaphragm |
| Name the organs contained in the abdominal cavity | gallbladder, liver, spleen, stomach, small intestine, most of the large intestine, kidneys, pancreas and ureters |
| Name the organs contained in the pelvic cavity | bladder, colon, rectum and internal reproductive organs |
| Layers of tissue that cover organ surfaces, line body cavities and form tubes | membranes |
| Body membranes come from these two basic tissue groups | epithelial tissue and connective tissue |
| These membranes are classified by where they are located in the body | epithelial |
| Cavities that each contain a lung | pleural cavities |
| Types of epithelial membranes | cutaneous, mucous, serous |
| Outer layer of the skin | cutaneous membrane |
| Membranes that line every tube or cavity that connects to the surface of the body | mucous membranes (mucosa) |
| Membranes that line the major body cavities that do not connect to the outside surface of the body | se |
| Name the organs contained in the pelvic cavity | bladder, colon, rectum and internal reproductive organs |
| Layers of tissue that cover organ surfaces, line body cavities and form tubes | membranes |
| Body membranes come from these two basic tissue groups | epithelial tissue and connective tissue |
| These membranes are classified by where they are located in the body | epithelial |
| Types of epithelial membranes | cutaneous, mucous, serous |
| Outer layer of the skin | cutaneous membrane |
| Membranes that line every tube or cavity that connects to the surface of the body | mucous membranes (mucosa) |
| Membranes that line the major body cavities that do not connect to the outside surface of the body | serous membranes (serosa) |
| Name the pair of serous membranes | parietal and visceral |
| Membranes that cover the organs | visceral |
| Membranes that line the cavity | parietal |
| Function of serous membranes | put out a serous fluid (serum) that lubricates the organs and reduces friction |
| Function of mucous membranes | secrete mucus which prevents cavities from drying out |
| Function of cutaneous membrane | protective outer layer of skin (waterproof) |
| Viscus (pl. viscera) | name of each large organ in a major body cavity |
| Serous membrane lining the thoracic cavity | pleura |
| Serous membrane lining the pericardial cavity | perietal pericardium |
| Serous membrane covering the heart | visceral pericardium |
| Membrane lining the pleural cavities | perietal pleura |
| Membrane covering the lungs | visceral pleura |
| Largest serous membrane which protects the abdominopelvic cavity | peritoneum |
| Membrane lining the abdominopelvic cavity wall | perietal peritoneum |
| Membrane covering some of the organs in the abdominopelvic cavity | visceral peritoneum |
| Types of connective tissue membranes | synovial, cranial and spinal canal |
| Membranes that line the joints and secrete a fluid to cushion them | synovial membrane |
| Membranes that line the cranial cavity and spinal canal | meninges |
| Layers of meninges | dura mater (outer meninx), arachnoid (middle meninx) and pia mater (inner meninx) |
| Referring to organs located behind the perietal serosa | retroperitoneal |
| Referring to organs/structures located outside of the pleura membranes | extrapleural |
| Perietal serosa lining the cranial cavity and spinal canal | dura |
| The combination of the perietal and visceral serosa lining the cranial cavity and spinal canal | meninges |
