NBME 26| Questions and Answers, 100% Correct 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 folli...

Immunology Exam 2 - Questions and Answers NKG2D is an activating receptor expressed on NK cells, : T cells, and some cytotoxic : T cells. When stressed or infected cells up-regulate receptors that bind to and activate NKG2D molecules, the stressed or infected cells will be killed. This pathway relies on the fact that stressed or infected cells up-regulate: A. All classical MHC class I molecules B. HLA-C molecules that bind KIRs C. MHC class Ib genes such as MICA, MICB, and RAET1 D. Qa-1 and HLA...

NBME EXAM QUESTIONS & ANSWERS 2024/25 LFA-1 integrin - ANSWERSCD11, cell adhesion molecule that binds ICAM - so the defect is in tight adhesion (PECAM is transmigration). DNI vs DNR - ANSWERSdo not intubate (tube), DNR is like atropine, chest compressions. Creatine is secreted or absorbed - ANSWERSSecreted at the PCT. proximal convoluted tubule (PCT) - ANSWERSsegment of the nephron between the glomerular capsule and the nephron loop What is the arcuate nucleus? - ANSWERS1 of 4 d...
