• Aortic Arch: portion of the main artery that bends between the ascending and descending aorta
...
○ Descending Aorta: beginning at the aortic arch and runs down through the chest and abdomen
...
• Atrium (right): right upper chamber of the heart
• Atrium (left): one of the four chambers of the heart, located on the left posterior side
...
• Brachial Plexus: network of nerves that originate in the neck region and branch off to form most of the other
nerves that control movement and sensation in the upper limbs, including the shoulder, arm, forearm, and
hand
...
The carina usually sits in the T4/T5 plane and is at the level of the sternal angle
...
• Clavicle (right and left): located between the sternum and the scapula, it connects the arm to the body
...
It runs behind the trachea and heart, in
front of the spine
...
○
Head of humerus (right and left): the "ball" portion of the joint
...
This is the wall that borders spetum between
the left and right ventricle
...
• Lung (right and left): located on either side of the chest
...
The
inferior border, oval and rough, is covered with a thin layer of cartilage for articulation with the body
...
○ Pericardium: a double-walled sac containing the heart and the roots of the great vessels
...
• Pulmonary Trunk: a major vessel of the human heart that originates from the right ventricle
...
• 1st Ribs (right and left):
• Superior Vena Cava: (SVC)the superior of the two venae cava, the great venous trunks that return
deoxygenated blood from the systemic circulation to the right atrium of the heart
...
• Spinal Cord: long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla
oblongata in the brainstem to the lumbar region of the vertebral column
...
It connects
to the ribs via cartilage, forming the front of the rib cage, and thus helps to protect the heart, lungs, and major
blood vessels from injury
...
Easily felt as
a small protuberance on the upper part of the chest, and it marks the location of the second rib
...
• Trachea: begins just under the larynx and runs down behind the sternum
...
• Thoracic vertebra 1-12: the upper and middle back
...
The thoracic spin is
made up of 12 vertebrae
...
• Ventricle of the Heart (left): One of the heart's four chambers; located in the bottom left portion of the heart
below the left atrium
...
Lower part of the sternum, which is usually ossified in the
adult human
