Transpyloric planeThe transpyloric plane, also known as Addison's plane, is an imaginary horizontal plane, located halfway between the suprasternal notch of the manubrium and the upper border of the symphysis pubis at the level of the first lumbar vertebra, L1. It lies roughly a hand's breadth beneath the xiphisternum or midway between the xiphisternum and the umbilicus.
Supracristal planeSupracristal plane (Planum supracristale) (or supracrestal plane) is an anatomical transverse plane lying at the upper most part of the pelvis, the iliac crest. According to Gray's Anatomy, this anatomical plane crosses the upper border of the spinous process of L4 (fourth lumbar vertebra). It lies about half an inch below the level of the transumbilical plane and therefore passes through the umbilical region and the left and right lumbar regions.
Subcostal planeThe subcostal plane is a transverse plane which bisects the body at the level of the 10th costal margin and the upper border of the third lumbar vertebra.Intertubercular planeA lower transverse plane midway between the upper transverse and the upper border of the pubic symphysis; this is termed the intertubercular plane (or transtubercular), since it practically corresponds to that passing through the iliac tubercles; behind, its plane cuts the upper border of the fifth lumbar vertebra (L5).
Aortic archThe aortic arch, arch of the aorta, or transverse aortic arch (English: ) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea. StructureThe aorta begins at the level of the upper border of the second/third sternocostal articulation of the right side, behind the ventricular outflow tract and pulmonary trunk. The right atrial appendage overlaps it.
Superior vena cavaThe superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm) short length (~7 cm) vein that receives venous return from the upper half of the body, above the diaphragm. Venous return from the lower half, below the diaphragm, flows through the inferior vena cava.
Thoracic ductIn human anatomy, the thoracic duct (also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's duct) is the larger of the two lymph ducts of the lymphatic system (the other being the right lymphatic duct).
HeartOrgan found in humans and other animalsThe heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. The heart and blood vessels together make up the circulatory system. The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs.
Thoracic diaphragmThe thoracic diaphragm, or simply the diaphragm (; Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 'partition'), is a sheet of internal skeletal muscle in humans and other mammals that extends across the bottom of the thoracic cavity.
LiverThe liver is a major metabolicorgan exclusively found in vertebrates which performs many essential biological functions, such as detoxification of the organism and the synthesis of various proteins and various other biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm and mostly shielded by the lower right rib cage.
MediastinumThe mediastinum (from Medieval Latin: mediastinus, lit.'midway';pl.: mediastina) is the central compartment of the thoracic cavity. Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, mainly the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph nodes of the central chest.
Transumbilical planeThe transumbilical plane or umbilical plane, one of the transverse planes in human anatomy, is a horizontal line that passes through the abdomen at the level of the navel (or umbilicus). It also intersects the intervertebral disc between the third (L3) and fourth (L4) lumbar vertebrae. This horizontal anatomical plane lies about half an inch above the level of the supracristal plane.
Carina of tracheaThe carina of trachea (also: "tracheal carina") is a ridge of cartilage at the base of the trachea separating the openings of the left and right main bronchi. StructureThe carina is a cartilaginous ridge separating the left and right main bronchi that is formed by the inferior-ward and posterior-ward prolongation of the inferior-most tracheal cartilage.*As an Amazon Associate I earn from qualifying purchases.
