Anatomy of the mediastinum: illustrations and cross-sections
Thorax : Cross-sectional anatomy
This anatomical module is about the anatomy of the mediastinum and the sectional anatomy of the thorax.
This thoracic anatomy tool is especially useful for students (medical and paramedical studies).
Anatomical atlas of the mediastinum and thorax : illustrated anatomical plates and cross sectional anatomy
Anatomical illustrations of the mediastinum and thorax by sections
All the anatomical illustrations are original and created by Micheau, Antoine - MD. They were drawn in Illustrator using 3D modeling derived from medical imaging (principally thoracic scan) or scannography sections of the thorax.
Mediastinum and thorax : Illustrations and anatomical cross-sections : Lateral view , Left
The different anatomical charts are organized in their representation of the general anatomy of the mediastinum and thoracic cavity, then its structure in details and finally the anatomical sections are available at the end of the module:
Mediastinum: Anterior view
Mediastinum: Right lateral view
Mediastinum: Left lateral view
Mediastinum: Posterior view
Upper opening of the thorax
Anterior mediastinum - Thymus
Superior venae cavae
Lymphatic trunks and channels
Thoracic lymph nodes
Vagus nerve [X]
Superior thoracic aperture; Thoracic inlet
Labeled anatomical structures of mediastinum and thorax in transverse sections:
300 anatomical structures were labeled on these diagrams of thoracic anatomy, accessible on the "Anatomical parts" tab:
Bones: principally ribs and sternum
Joints: the different joints of the thoracic cage (costosternal and costotransverse joints...) are presented
Ligaments: various ligaments uniting the dorsal vertebrae, ribs and sternum (costotransverse, costoclavicular and sternocostal ligaments).
Arteries: includes the various arteries in the mediastinum (aortic, TABC, carotid and subclavian)
Aorta : Anatomy
Veins: includes the superior vena cava and its principal venous afferences (azygos vein, brachiocephalic veins...)
Superior vena cava: Antero-lateral view
Lymphoid system: thymus and lymphatic ganglia
Thoracic lymph nodes: Posterior view
Nerves: details the nervous anatomy of the mediastinum including notably the route of the phrenic and vagus nerves as well as the anatomy of the sympathetic trunk at the thoracic level.
Vagus nerve [X]
Heart: the external morphology of the heart in the mediastinum and the various chambers of the heart on the anatomical sections are detailed on these diagrams.
Lungs: pulmonary lobes and segments in sectional anatomy
Bronchi: the trachea and bronchial tree with their anatomical relationship with the mediastinum are captioned
Pleura / Pericardium: anatomical relationships and arrangement of pleural and pericardial cavities in the thoracic cavity.
Pulmonary arteries: anatomy of the pulmonary trunk and the right and left pulmonary arteries in the mediastinum.
Pulmonary veins: particularly visible on the anatomical charts of the mediastinum in posterior view and on the anatomical sections of the thorax.
Digestive system: mainly the oesophagus in its thoracic portion
Oesophagus : Anatomical illustrations
Language and terminology for the study of the anatomy of the thorax
We used the Terminologia Anatomica to label all the anatomical structures, with translations available in English, French, Japanese, German, Chinese, Portuguese, Russian, Polish, Korean, Italian and Spanish.
