Summary Introduction

To review:

The nerve that, when injured, causes paralysis in the serratus anterior muscle.

Introduction:

The roots of the spinal nerves starting from the C5 to C8 and the nerve coming from the thoracic end unite to form the brachial plexus, which runs laterally and inferiorly on both sides of the last four and first cervical and thoracic vertebrae. The serratus anterior muscle is a muscle which carries the role for the protraction of the scapula that is, pulling of scapula forward and around the rib cage when someone throws a punch.

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.
