Textbook Question
Chapter 18, Problem 1CCS
Mr. Hutchinson, another middle-aged victim of the collision on Route 91, has a tourniquet around his thigh when admitted in an unconscious state to Noble Hospital. The emergency technician who brings him in states that his right lower limb was pinned beneath the bus for at least 30 minutes. He is immediately scheduled for surgery. Admission notes include the following:
Multiple contusions of lower limbs
Compound fracture of the right tibia; bone ends covered with sterile gauze
Right leg blanched and cold, no pulse
Blood pressure 90/48; pulse 140/min and thready; patient diaphoretic (sweaty)
Relative to what you have learned about tissue requirements for oxygen, what is the condition of the tissues in the right lower limb?

Please help me to draw this by hand. In as much detail as possible, hand draw a schematic diagram of the hypothalamic-pituitary-gonad (HPG) axis in the human female. Be sure to include all the relevant structures and hormones. You must define all abbreviations the first time you use them. Please include (and explain) the feedback loops.

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?arrow_forward

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
