Thorax
Thoracic wall
The thoracic wall is comprised mainly of the ribs, the sternum and the thoracic muscles.
-
Bones of the thoracic cavityThe sternum and the ribs are the bones of the thoracic cage.
-
SternumBony elements of the sternum.
-
RibsMain features of the ribs
-
Muscles of the thoracic wallMain muscles found in the thorax.
-
Nerves and vessels of the anterior thoracic wallMain arteries, veins and nerves of the anterior thoracic wall.
-
Neurovasculature of the intercostal spaceMain vessels and nerves of the intercostal space from a superolateral view.
Female breast
The breasts are paired milk-producing organs in the upper ventral sides of the torso. They contain the mammary glands which secrete milk used to feed infants.

Blood vessels of the female breastArteries and veins of the female breast.
-
Lymphatics of the female breastLymph vessels and nodes of the female breast.
Mediastinum
The mediastinum is found in the midline of the thorax and is surrounded by the left and right pleural sacs. Many structures are found within this area.

Esophagus
The esophagus is a long fibromuscular tube connecting the pharynx with the stomach. Here we will learn the structures that pass alongside and supply this organ.

Diaphragm
The diaphragm is a muscle residing within the trunk and separates the thoracic and abdominal cavities. Many structures pass through it, including blood vessels.
