Mnemonics for week 4 and 5...

Description

Mnemonics for Week 4 Rib costal groove: order of intercostal blood vessels and nerves VAN (from superior to inferior) Vein Artery Nerve Diaphragm innervation “C3, 4, 5 keep the diaphragm alive” Diaphragm innervation is by cervical roots 3, 4, and 5 (phrenic nerve) Lingula location: LingULa Left Upper Lobe Lung lobe numbers/Heart AV valves: right vs. left Right side: Tricuspid heart valve and tri-lobed lung Lef side: Bicuspid heart valve and bi-lobed lung

Atrioventricular (AV) valves: LAB RAT Left Atrium: Bicuspid valve Right Atrium: Tricuspid Semilunar valve cusps: Aortic and pulmonary Both of them have a right and left cusp, but one has an anterior cusp and one has a posterior cusp Pulmonary trunk is anterior to the Aorta It has the anterior cusp (right, left and anterior cusps) Aorta is posterior to the pulmonary trunk It has the posterior cusp (right, left and posterior cusps)

Aortic Arch: major branch order Know your ABC’S: Aortic arch gives rise to: Brachiocephalic trunk Left Common Carotid artery Left Subclavian artery

 Beware of the trick question of “What is the first branch of the aorta?” Technically, it’s the coronary arteries. Coronary circulation: arteries and associated veins Small Margin: Small vein and Marginal artery Middle schoolers show Public Display of Affection (PDA): Middle Vein and Posterior Descending Artery Great LAD: Great vein and Left Anterior Descending artery CC’s: Coronary sinus and Left Circumflex artery

Main Bronchi: which one is more vertical? “Inhale a bite, it goes down the right”  Inhaled objects are more likely to lodge into the right main bronchus, since it is the one that is more vertical.

Mnemonics for Week 5 Pulmonary artery location on each lung, in relation to the bronchi. RALS Right lung the pulmonary artery will be Anterior to the main bronchi. Left lung the pulmonary artery is located Superior to the main bronchi. Remember the bronchi have cartilage so they should be easy to identify. Diaphragm apertures: spinal levels “I 8 10 Eggs At 12” (read this as “I ate ten eggs at twelve” if it doesn’t look right to you) Interior Vena Cava T8 T10 Esophagus Aorta  T12 Posterior mediastinum contents: DATES Descending aorta Azygous and hemiazygous vein Thoracic duct Esophagus Sympathetic trunk/ganglia

External carotid artery branches “Some Angry Lady Figured Out PMS”

Superior thyroid artery Ascending Pharyngeal artery Lingual artery Facial artery Occipital artery Posterior auricular artery Maxillary artery Superficial Temporal artery  Alternative: As Steve Lay Frozen Olive Palpated Some More
