Chapter 22, Problem 4CCS
35-Year-Old Female with Chest Trauma
Barbara Joley was in a major car accident. When EMS managed to free her from the wreckage, she was cyanotic and apneic (not breathing). Her heart was still beating, but her pulse was fast and thready. The emergency medical technician reported that when Barbara was found, her head was cocked at a peculiar angle and it looked like she had a fracture at the level of the C2 vertebra. The following questions refer to these observations.
4.NCLEX-STYLE How do Barbara's recorded injuries relate to the pneumothorax?
a. The pain from her broken ribs is causing her to decrease breathing, so the right lung is not inflating.
b. Barbara’s fractured ribs probably punctured her lung tissue and allowed air within the lung to enter the pleural cavity.
c. When the level of O2 in the blood decreases, a negative feedback loop involving the central chemoreceptors causes lung inflation to decrease as well.
d. Her traumatic injury has caused her peripheral chemoreceptors to stop working, so they are not causing her to increase ventilation.

"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region."
My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.
1. pronodal cleaved by protease -> active nodal
2. Nodal -> BMP4 -> Wnt-> nodal
3. Nodal-> Nodal, Fox1 binding site
4. BMP4 on outside-> nodal
Are all of these occuring opposite to AVE?

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forward
