Objectives for the Thorax (Chapter 3)
Gray’s Anatomy for Students
Conceptual Overview
When you have completed this section, you should be able to:
1. Describe the general function of the thorax as well as its general divisions.
2. Describe and discuss the components and general organization of the thorax and thoracic
viscera as well as it relationship with other regions of the body (neck, upper limb,
abdomen, and breast).
3. Identify and describe the key features of the thorax, including the segmental nature of the
thorax.
Regional Anatomy of the Lower Limb
When you have completed this section, you should be able to:
Pectoral Region
1. Describe the vascular supply, innervation and lymphatic drainage of the breast.
2. Identify and describe the attachments, actions and innervation of the muscle of the
pectoral region.
Thoracic Wall
1. Identify and discuss the skeletal framework of the thorax as well their articulations and
movements.
2. Identify and discuss the contents of the intercostal space, including, vascular supply,
innervation, muscular, and lymphatic components.
3. Describe the attachments, actions and innervation of the diaphragm.
4. Identify and describe the structures that traverse the diaphragm relative to other key
anatomic structures.
Pleural Cavities
1. Identify and describe the pleura, including its reflections, recesses, and innervation.
2. Identify lines of reference on the thoracic wall as they related to external and internal
structures.
3. Describe the general anatomic features of the lungs.
4. Describe the pulmonary vasculature, innervation, and lymphatic drainage.
Mediastinum/Pericardium
1. Identify and discuss divisions and structures found within the mediastinum.
2. Describe the structure, attachments, and relations of the pericardium, including
pericardial sinuses.
3. Discuss the vascular supply and innervation of the pericardium.
Heart
1. Discuss the orientation and general features of the heart.
2. Describe the flow of blood through the heart.
3. Describe and identify the anatomic structures of the heart chambers and cardiac
supporting structures.
4. Discuss the coronary vasculature including its location, distribution and anatomic
variations.
5. Identify and discuss the nerve supply to the heart and the cardiac conducting system.
Superior Mediastinum
1. Identify and discuss the boundaries and contents of the superior mediastinum including
their vasculature, innervation and lymphatic drainage.
2. Discuss the vasculature and nerve structures that pass through and innervate the region.
3. Identify and discuss the venous drainage of this region as it related to the rest of the
thorax.
Posterior Mediastinum
1. Identify and discuss the boundaries and contents of the posterior mediastinum including
their vasculature, innervation and lymphatic drainage.
2. Discuss esophageal relationships as they related to other structures within the thorax.
3. Discuss and describe the general pattern associated with the azygous system of veins.
Clinical and Surface Anatomy
When you have completed this section, you should be able to:
1. Identify the superficial landmarks associated with the thorax [features of the skin,
superficial and deep fascia, spaces, compartments, boney landmarks, muscles, ligaments,
nerves, vasculature and joints].
2. Apply anatomic knowledge and understanding to clinical scenarios presented in the
chapter (see green boxes).
