To explain: Why local cortisone injection in an inflamed joint is preferred over the administration of pill.
Concept introduction:
The adrenal cortex acts through the endocrine system under the stressful conditions such as reduced level of blood sugar, volume, and pressure. It stimulates the hypothalamus to secrete the releasing hormone. Then, the releasing hormone stimulates the secretion of the adrenocorticotropic hormone (ACTH) from the anterior pituitary. From the pituitary, ACTH reaches the adrenal cortex through blood circulation and stimulates corticosteroids secretion. Two types of corticosteroids are found in humans namely glucocorticoids (cortisol) and mineralocorticoids. Glucocorticoids or cortisol activates glucose synthesis from protein and are also involved in the breakdown of proteins into amino acids in muscles and influence the immune system.

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

- You inject morpholino oligonucleotides that inhibit the translation of follistatin, chordin, and noggin (FCN) at the 1 cell stage of a frog embryo.

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
