The diseases and conditions associated with the thyroid and the parathyroid gland. Introduction: Thyroid gland Is a large gland in the neck which is a cartilage of larynx. It is involved in secretion of hormones that helps in the regulation of body metabolism . Thyroid gland secretes: triidothyronine (T3) and thyroxine (T4). These hormones are important for the metabolism of the body. Also, it is important for the development and growth of the body. It controls the level of iodine in the body. The hormone calcitonin helps in the maintenance of blood calcium level. It plays important role in nerve conduction and muscle contraction. It also lowers the blood calcium level if it rises. Parathyroid glands are four small glands present in the neck. It helps in the control of calcium level of the body. These glands secrete parathyroid hormone (PTH). This hormone stimulates the activity of osteoclats that helps in the release of calcium ion from the bones. It also promotes the reabsorption of calcium ions by the kidney. This hormone helps in increasing the blood calcium level if it is low.

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.
