Summary Introduction

To determine:

The number of motor neurons need to carry the action potential from the spinal cord to smooth muscles in the wall of intestine.

Concept introduction:

Action potential is an electrical impulse that is needed to transfer the message from CNS to the organs muscles that carries out response to the stimulus. The source of energy for the development of the action potential is derived from the sodium and potassium ions. It is simply a concept of changes in the ionic concentration. It is produced by a type of passage or gate known as the voltage gated ion channels in the cell membrane.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
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.
