Image Observations !Thyroid gland showed one or more small, lightcolored nodules.Thyroid glands are brownish-red in color. We were able to see the oxyphil cell that are present in the parathyroid gland.The color of the parathyroid glands is typically light brown to tan, which relates to their fat content, vascularity, and percentage of oxyphil cells within the glands The pancreases is shaped like a flat pear The Aderenal Gland is small, triangular-shaped the anterior pituitary makes up the pituitary gland

What is a hormone?

Hormones are chemical messengers that travel

throughout the body coordinating complex processes like growth, metabolism, and fertility. ... In response to a signal from the brain, hormones are secreted directly into the blood by the glands that produce and store them.
