Summary Introduction

To analyze:

The ways that botulism toxin affects the neuromuscular junction and generates the symptoms.

Introduction:

Neuromuscular junction refers to the region where the motor neuron axon branches come in contact with the muscle fiber. Botulism interrupts the neural signal transmission by inhibiting the release of acetylcholine, which acts as the neurotransmitter at the neuromuscular junction.

Students have asked these similar questions

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.
