Study Notes
Orbital Anatomy
- The apex of the orbit is directed upward.
- The optic canal represents the apex of the orbit, connecting the orbit to the middle cranial fossa.
Muscles of the Eye
- The levator palpebrae superioris muscle is supplied by the oculomotor nerve.
- The lateral rectus muscle is supplied by the abducent nerve.
- The superior oblique muscle is supplied by the trochlear nerve.
Thoracic Anatomy
- The suprasternal notch is significant for localizing the trachea, which must be centrally located normally.
- The sternum is used for bone marrow aspiration due to its hematopoietic activity throughout life.
- The thymus is a primary lymphoid organ responsible for the development of B lymphocytes.
- The thymus starts to slowly shrink and becomes replaced by fat once you reach puberty.
- The largest lymphatic vessel in the body is the thoracic duct.
- The pulmonary veins receive oxygenated blood from the lungs, delivering it to the left side of the heart to be pumped back around the body.
Pelvic Anatomy
- The sacrum forms the posterior wall of the pelvis.
Thoracic Cage Anatomy
- The manubriosternal angle (angle of Louis) is formed by the articulation of the manubrium and body of the sternum.
- The manubriosternal angle lies at the level of the 1st costal cartilages anteriorly and opposite to the lower border of T3 posteriorly.
Intercostal Muscles
- The external intercostal muscle is an inspiratory muscle that elevates the ribs.
Surface Anatomy
- The nipple is used to localize the location of the apex beat of the heart.
