NBME 26 Questions Answered 100% correct 2023 How can the jejunum be distinguished from the ileum? (5) 1. inner mucosal folds (plicae circulares) are more prominent, more numerous, and taller --> (this leads to increased mucosal SA and associated feathered appearance after the administration of oral contrast material) 2. larger caliber, thicker muscular walls 3. longer vasa rectae 4. fewer arcades 5. the ileum is notable for the presence of Peyer patches and mucosal lymphoid fo...

NBME Questions Answered 100% correct 2023 LFA-1 integrin CD11, cell adhesion molecule that binds ICAM - so the defect is in tight adhesion (PECAM is transmigration). DNI vs DNR do not intubate (tube), DNR is like atropine, chest compressions. Creatine is secreted or absorbed Secreted at the PCT. proximal convoluted tubule (PCT) segment of the nephron between the glomerular capsule and the nephron loop What is the arcuate nucleus? 1 of 4 dopaminergic pathways. Pr...

NBME 26 Questions Answered 100% correct 2023 Absence of the gamma region on SPEP indicates immunodeficiency with hypogammaglobulinemia or agammaglobulienmia increased left atrial pressure during ventricular systole on the pressure-time graph indicates mitral regurgitation, likely from rupture of the chordae tendinae Mannitol's effect on serum osmolality increases serum osmolality (and in turn, triggers production of ADH) hypoventilation is characterized by increased Pa...

Characteristics of Dysplasia - ANSWER-Loss of uniformity of cell size and shape = pleomorphism, Loss of tissue orientation, Nuclear changes - increase nuclear:cytoplasmic ratio and clumped chromatin Reversible cell changes to injury - ANSWER-Cellular and mitochondrial swelling due to reduce ATP leading to reduce activity of Na/K and Ca pumps, Membrane blebbing, Nuclear chromatin clumping, Ribosomal / polysomal detachment (reduced protein synthesis). Irreversible cell changes to ...
