Summary Introduction

To review:

Match the term diastole with the most closely related descriptions given below:

Vein to the left atrium

Covers outer surface of the heart

Supplies blood to heart muscle

Lines inner surface of fibrous pericardium

Slow heart rate

Functional syncytium

Muscular wall of the heart

Relaxation phase of the cardiac cycle

Vein to the right atrium

Contraction phase of the cardiac cycle

Introduction:

The cardiac cycle has two phases, including systole and diastole, which is detected in the form of a heartbeat. The systole is accompanied with a ‘lub’ sound and the diastole with a ‘dub’ sound. These sounds are generated when the valves between the heart’s chambers open and close as blood pass through them.

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.
