0 out of 1.7 points Which of the following ligaments prevents the knee joint from rotating in the anatomical position? Selected Answer: Popliteal ligament Answers: Popliteal ligament Collateral ligaments Cruciate ligaments Patellar ligament Response Feedback: When the knee joint is extended, both the collateral ligaments are tight. When it’s flexed, they become less tight. The function of the collateral ligaments is to keep the femoral and tibial condyles together, and thus to prevent the knee joint from bending from side to side. In addition to the obvious knee movements - flexion and extension - it’s also possible for the tibia to rotate a little on the femur. This rotation can happen only when the knee is flexed - when it’s extended the tightness of the collateral ligaments makes rotation impossible.
1.7 out of 1.7 points Which of the following order is correct from lateral to medial for distal row of the carpal bones? Selected Answer: Trapezium-Trapezoid-Capitate-Hamate Answers: Scaphoid-Lunate-Triquatral-Psiform Psiform-Triquatral-Lunate-Scaphoid Trapezium-Trapezoid-Capitate-Hamate Hamate-Capitate-Trapezoid-Trapezium Response Feedback: The proximal row of carpal bones, as seen in a lateral to medial direction on the palmar surface, include: the scaphoid bone the lunate bone the triquetral bone

1.8 out of 1.8 points A hypothetic mutation results in the following: Alanine is replaced by glutamic acid (In other words, Glutamic acid takes the place of alanine). Which change would be expected in the proierties of this protein? Selected Answer: Ionic interactions would increase. Answers: The number of peptide bonds would increase. Ionic interactions would increase. Hydrophobic interactions would increase. Water-solubility of the protein would decrease. A new disulfide bond would be formed. Response Feedback: Correct response: Ionic interactions would increase (Glutamic acid which incorporates into the protein is ionic). Incorrect responses: The number of peptide bonds would increase (No, the number of amino acids stays the same). Hydrophobic interactions would increase (No, glutamic acid is ionic). Water-solubility of the protein would decrease (No, it would increase because Glutamic acid is ionic). A new disulfide bond would be formed (No, cysteine is the amino acid involved in the disulfide bond).
