Chapter 22, Problem 1RQ
Summary Introduction
To determine:
The phrenic nerves cutting will result in
(a) air entering the pleural cavity,
(b) paralysis of the diaphragm,
(c) stimulation of the diaphragmatic reflex,
(d) paralysis of the epiglottis.
Expert Solution & Answer
Answer to Problem 1RQ
Solution:
(b) Paralysis of the diaphragm
Explanation of Solution
The phrenic nerves begin at the neck and move down between the lungs and heart. They then finally reach the diaphragm. These nerves are crucial for breathing because they transfer the motor information to the diaphragm. The pleural cavity does not consist of phrenic nerves. The laryngeal nerves are present in the epiglottis.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud.
What is the phenotype of the resulting ectopic limb?
Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
