The thoracic cavity is the largest part of the body. It contains the heart and other organs, and is bordered on either side by two pleural cavities. These cavities are located on either side of the ribs. The thoracic cavity is divided into three compartments: the anterior, middle, and posterior thoracic cavities. A superficial groove is present on the left side of the thoracic cavity, which allows blood and nerves to travel through.
Anatomy of the thoracic cavity starts with the boundaries. The thoracic wall is composed of a skeletal framework, fascia, and muscles, and is a strong protective cage. The thorax has two major openings: the superior and the inferior thoracic apertures. The former is bounded by the bones of the upper thorax, while the latter is surrounded by the sternum and the thoracic vertebrae.
The thoracic cavity is divided into three well-established compartments. The anterior and posterior thoracic bones are connected by the sternum, which is the first part of the thoracic cavity. The thoracic ribs articulate with the T1-T12 thoracic vertebrae and attach via costal cartilages to the sternum.
The thoracic cavity is located deep within the thoracic wall. It is separated from the neck by the diaphragm, and is lined by the pleura and pericadium, which line the internal walls of the lungs. These structures provide space and protection to the lungs and the heart. Several organs and structures are located in the thoracic cavity.
The thoracic cavity is composed of three parts. The sternum is the main anchor of the anterior thoracic cage. The manubrium is the superior portion of the sternum with a shallow U-shaped border. The clavicular notch is the site of the sternoclavicular joint. All these anatomical features are located in the thoracic cavity.
The thoracic cavity is divided into several compartments. The mediastinum is the central compartment, bordered by the internal intercostal muscles and the two pleural cavities on the lateral side. The inferior thoracic wall is composed of the anterior, middle, and posterior compartments. The inferior thoracic wall is curved and extends to the posterior border of the sternum.
The thoracic cavity is divided into three compartments. The mediastinum is the central compartment, while the other two are the lateral compartments. Each one communicates with the other compartments via the sternum and the thoracic vertebral bodies. The thoracic wall and its internal structures are made up of a number of bones. In addition to this, the thoracic cavity is made up of two ribs.
The thoracic cavity is divided into three compartments. The two pleural compartments contain the right and left lungs. The third compartment is the mediastinum. The mediastinum is the central and most important part of the thoracic wall. The thoracic wall consists of six sections. In each, the thoracic bones are located in their proper positions.
The thoracic cavity is divided into three compartments by the thoracic wall. Each compartment is lined by two types of mesothelium: the pleura, which lines the lungs, and the pericadium, which lines the heart and thoracic vertebral bodies. The two compartments communicate with the abdominal cavity via the inferior thoracic wall.
The thoracic cavity contains three main components: the thoracic ribs, the heart, and the internal jugular cavity. The thoracic wall is made up of the thoracic vertebral bodies. The pericardial sac is located in the thoracic area. In contrast, the pericardium is divided in two parts by the thoracic arteries.
The thoracic cavity is divided into two parts by the diaphragm. The thoracic cavity is surrounded by the pericardial tissue. The abdominal region is divided by the diaphragm. The chest is surrounded by the pleura of the lungs and the transverse process of the heart. The abdominal region is the home of the reproductive organs.
