Summary Introduction

To explain:

How motor neurons action potential can trigger a skeletal muscle fiber contraction?

Introduction:

Motor neuron transmits signals to muscle fibers at a point known as a neuromuscular junction. It stimulates muscle contraction by sending a nerve signal to muscles through a neurotransmitter known as acetylcholine. Acetylcholine helps to stimulate the skeletal muscle. It is released in sarcolemma and changes the permeability of sodium and potassium ions.

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.
