Study Notes
Respiratory Anatomy
- Parietal refers to the wall of the body cavity.
- Visceral refers to the internal organs of the body, specifically those within the chest (e.g., heart or lungs) or abdomen (e.g., liver, pancreas, or intestines).
Viscera
- The plural form of "viscera" refers to the internal organs of the body.
- The singular form of "viscera" is "viscus", which is Latin for "an organ of the body".
- In a figurative sense, "visceral" refers to a feeling that is deep-seated or intense, often described as a "gut feeling".

Thoracic Cavity
- The thoracic cavity, also known as the "chest", is the region where the lungs are located.
- It is bounded caudally (inferiorly) by the diaphragm, a thin, flat muscle that separates the thorax and abdomen.
Diaphragm
- Contraction of the diaphragm results in inhalation.
Ribs and Intercostal Muscles
- The thoracic cavity is bounded laterally by the ribs and intercostal muscles.
- The ribs are flexible, thin bones with cartilage connections dorsally and ventrally.
- This allows for movement of the thorax while providing structure and preventing collapse during inspiration.
- The ribs also provide protection to the heart and lungs, which are vital organs.
Intercostal Muscles
- Intercostal muscles are the muscles between the ribs.
- They assist in ventilation.
Thoracic Vertebrae
- The thoracic cavity is bounded dorsally by the thoracic vertebrae, which form the spinal column.
Sternum
- The thoracic cavity is bounded ventrally by the sternum, which is connected to the ribs by cartilage.

Thoracic Cavity Boundaries
- Laterally, the thoracic cavity is bounded by the ribs and intercostal muscles.
- The ribs are flexible, thin bones with cartilage connections dorsally and ventrally, allowing for movement of the thorax while providing structure and protection to the heart and lungs.
- The intercostal muscles, located between the ribs, assist in ventilation.
Thoracic Cavity Boundaries (continued)
- Dorsally, the thoracic cavity is bounded by the thoracic vertebrae, which form the spinal column.
- Ventrally, it is bounded by the sternum, which is connected to the ribs by cartilage.
- Cranially, the thoracic cavity is bounded by the thoracic inlet, where all the structures pass between the neck and thorax, including blood vessels, oesophagus, trachea, and others.
Mediastinum
- The mediastinum is the area between the lungs, containing the trachea, heart, oesophagus, blood vessels, and connective tissue.
- It is divided into cranial (pink) and caudal (purple) mediastinum.
