Scribepost: April 23

So, on Friday we learned about the Thyroid Glands and talked about the Adrenal Glands.

-TSH is produced in response to hypothalamic releasing factor
>increase metabolic rate
>Stimulate all body cells
>More glucose is utilized to form ATP
>Necessary for normal growth and nervous system function

-Thyroid requires iodine to produce these hormones
>Iodine deficiency causes simple goiter

-Then we learned about the 3 different disorders that were related to the thyroid.
1. Cretinism

Abnormal thyroid development

-Short, stocky body type
-Severe hypothyroidism
-Mental retardation
-Treatment must begin in first 8 weeks of life

On the left is the scull of a person who was a cretin and on the right is the scull of a regular person.

But anyways, linking this to real life. I was watching house on Monday, so yesterday night. They were talking about some kind of a disease that had to do with the adrenal glands, they went on to do a CAT scan, where they needed to look closely at the medulla oblongata. It was pretty cool that we actually learned about that stuff, and I sort of knew what they were talking about.
