HN: The Thoracic Cavity if surrounded by an ____________________ thoracic cage
Osteocartilaginous
42
HN: The Thoracic cavity contains 3 primary divisions: What are they?
Two **pulmonary cavities** (located laterally, contain lungs) **Mediastinum** (located centrally, contains heart, thoracic great vessels, trachea, thoracic esophagus, thymus)
43
What does the **mediastinum** contain?
Heart Thoracic Great Vessels Trachea Thoracic Esophagus Thymus
44
CN: Which are the most commonly fractured ribs?
MIDDLE RIBS
45
CN: What are **supernumerary ribs?**
Extra ribs in either the cervical region or lumbar region
46
What are the three types of joints?
1. Synovial Joint (Diarthrosis) 2. Fibrous Joint (Synarthrosis) 3. Cartilaginous Joint (Amphiarthrosis)
47
What are the two forms of movement that occur at the **costovertebral joint?** Describe their movement
1. **Bucket Handle movement**: Increases transverse diameter of the thorax 2. **Pump Handle movement:** increases the anterior-posterior diameter of the thorax
48
CN: What does a **dislocation** of ribs refer to?
Dislocation at the **Sternocostal joint**
49
CN: What does a **separation of ribs** refer to?
Separation at the costochondral joint
50
CN: Describe **Thoracentisis**
Insertion of needle through **intercostal musculature** b/w ribs to obtain a fluid sample or drain small amounts of blood or fluid from the pleural cavity Needle is inserted inferior to the *intercostal neurovascular bundle* and superior to the *collateral branches*
51
CN: Describe **Insertion of chest tube**
Insertion of a tube to remove large amounts of air, fluid, blood or pus from the pleural cavity Tube is inserted b/w 5th and 6th intercostal space
52
CN: Describe **thoroscopy**
Insertion of a thoroscope into the pleural cavity through small incisions for visualizing and biopsying the space inside the pleural cavity
