Textbook Question
Chapter 13, Problem 1WYL
Identify at least two surface features of the orbital region that protect the eye.
Expert Solution & Answer
Summary Introduction
To determine:
The surface features of the orbital region that is responsible for the protection of the eye.
Introduction:
The human face is divided into five different regions. These regions are auricular, orbital, nasal, oral, and mental. The region which includes eye and its related structures is known as orbital region.
Explanation of Solution
Most of the surface features of the orbital region are responsible for protecting the eye. There are three surface features of the orbital region. These features are as follows:
• Eyelids:
The function of eyelids is to protect the eyes against any object moving near the eye. It also prevents contact of airborne particles with the eyeball.
• Eyebrows:
They are responsible for protecting the eyes from sunlight and any possible mechanical damage to the eye.
• Superior palpebral fissure:
It is also known as upper eyelid crease. Most individuals can easily touch it. It also protects the eye.

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.

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
