QuestionChoice
The image shows an axial view of the thoracic cavity. Within the image, the heart is located centrally, with the left and right lungs surrounding it laterally. The arrow is pointing anteriorly, just behind the sternum. The anterior mediastinum lies between the sternum and the pericardium and is therefore the correct answer. The anterior mediastinum normally contains the remnants of the thymus.

a
Anterior mediastinum
QuestionChoice
The image shows an axial view of the thoracic cavity. Within the image, the heart is located centrally, with the left and right lungs surrounding it laterally. The inferior mediastinum is a large division of the thoracic cavity which contains three subdivisions – the anterior, middle and posterior mediastinum. While the anterior mediastinum is contained within the inferior mediastinum, this answer is not very specific to the area indicated by the arrow.

d
Inferior mediastinum
QuestionChoice
The image shows an axial view of the thoracic cavity. Within the image, the heart is located centrally, with the left and right lungs surrounding it laterally. The middle mediastinum lies between the anterior and posterior mediastinum. It is the central part of the thoracic cavity and contains the pericardium, heart and origin of the great vessels.

b
Middle mediastinum
QuestionChoice
The image shows an axial view of the thoracic cavity. Within the image, the heart is located centrally, with the left and right lungs surrounding it laterally. The arrow is pointing anteriorly. The posterior mediastinum by comparison, is found most posteriorly. The pericardium lies anteriorly and the domed part of the diaphragm lies inferiorly. Many important structures descend through the posterior mediastinum, including the oesophagus, thoracic aorta, azygos, hemiazygos, accessory hemiazygos veins, thoracic duct and lymph nodes.

c
Posterior mediastinum
QuestionChoice
The image shows an axial view of the thoracic cavity. Within the image, the heart is located centrally, with the left and right lungs surrounding it laterally. Given the lower level of this axial section (inferred by the presence of the heart), the compartment indicated by the arrow is the anterior mediastinum, which is a small compartment of the inferior mediastinum. The inferior border of the superior mediastinum is formed by an imaginary line between the sternal angle and the lower border of the T4 vertebra.
