Question
Chapter 39.3, Problem 1TC
Summary Introduction
To determine:
The skin areas that are especially sensitive to touch, and that differ from less sensitive areas.
Introduction:
Skin is the largest organ of the body. It has three layers. Epidermis is the outer layer of the skin that provides “waterproof barrier”. The dermis, present under the epidermis and it contains connective tissue and hair follicles. The deeper layer is made up of fat and connective tissue.
Skin receptors are the small cells known as sensory neurons. When skin comes in contact with something, the sensory neurons receive signals, and these signals travels to the brain.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage?
Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure?

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid.

- 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?arrow_forwardYou 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.arrow_forwardYou 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.arrow_forward
