Study Notes
Sensory Nerve Supply and Structure Relations
- The phrenic nerve supplies sensory fibers to the mediastinal parietal pleura, peritoneum, and pleura associated with the central tendon of the diaphragm.
- The right phrenic nerve passes through the caval hiatus.
Mediastinal Structures and Functions
- The thymus is located in the superior mediastinum and is active during childhood until puberty.
- The peritoneum lines the abdominal cavity.
Pericardium and Related Structures
- The pericardium has two layers: the fibrous pericardium and the serous pericardium, which includes parietal and visceral layers.
- Structures related to the right atrium include superior/inferior vena cava and the right pulmonary veins.
Anatomical Relationships and Clinical Considerations
- The transverse and oblique sinuses of the serous pericardium have specific positions, with the transverse sinus lying posterior to the ascending aorta.
- Key arteries in clinical anatomy of the thoracic aorta include those that branch from it and supply various thoracic structures.
Trachea and Veins
- The trachea starts at the cricoid cartilage (C6) and ends at the carina (T5).
- The brachiocephalic veins are formed by the junction of the internal jugular and subclavian veins.
Lymphatic Drainage
- The left thoracic lymph trunk drains lymph from the left thorax; the thoracic duct carries lymph from most of the body except specified regions.
- The thoracic duct opens into the venous system at the junction of the left internal jugular and left subclavian veins.
Thymus, Oesophagus, and Mediastinal Nodes
- The thymus is positioned in the superior mediastinum, offering important roles in immune function.
- Clinical anatomy of the oesophagus involves its position behind the trachea and anterior to the vertebral column.
- Mediastinal lymph nodes are pivotal in the spread of lung tumors.
Pericardial Cavity and Fluid
- The pericardial cavity is located between the parietal and visceral layers of the pericardium, containing pericardial fluid that reduces friction during heartbeats.
Diaphragm and Associated Structures
- The phrenic nerve also serves as the sole motor supply to the diaphragm.
- The right thoracic lymph trunk drains lymph from the right thorax.
Ribs and Associated Joints
- Commonly fractured ribs are typically ribs 5 to 9.
- The costovertebral joint forms between the rib tubercle and the transverse process of the corresponding vertebra, allowing for rib movement.
- The first rib has a unique anatomy with a shorter length and different orientation compared to other ribs.
Imaging and Complications
- Rib fractures can lead to complications such as pneumothorax, hemothorax, or lung contusions.
- Various anatomical atlases published by Elsevier and Lippincott Williams & Wilkins provide detailed images of rib fractures for clinical reference.
