Chapter 10, Problem 1RQ
Summary Introduction

To determine:

(a) Antagonist

(b) Prime mover

(c) Synergist

(d) Agonist

Answer to Problem 1RQ

Solution:

(c) Synergist: The term “synergist” refers to the working together of two or more components. Similarly, the combined effect thus generated is referred to as the synergistic effect.

Explanation of Solution

An agonist is a muscle that is responsible for generating a specific movement. It might also be referred to as the prime mover, for example, the pectoralis muscle. Synergists help the agonist or the prime mover in completing its movement by aiding a small amount offorce or avoiding the movements that are not necessary.

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.
