2. Define the following vocabulary terms: -Endocrine glands -Hormones -Thyroid gland -Parathyroid Glands -Pancreas -Pituitary Glands -Gonads -Adrenal Glands Lesson 1: The Endocrine System

3. 1. Describe the role of the pituitary gland. What are the three different lobes within this gland and what are they responsible for? 2. Describe the role of the Adrenal Gland. What are the two parts of the Adrenal gland and what purpose to they serve? 3. What are problems that occur within the Endocrine system? List three and discuss which you believe is most prevalent in our society.

4. The Endocrine System is a network or glands within the body. Endocrine glands are ductless organs or groups of cells that secrete hormones directly into the blood. Hormones are chemicals that the body’s glands produce. They help control many of your body’s functions. The following slides discuss some of these major glands: Structure of the Endocrine System

5. Pituitary Gland This is the master gland. It controls the action of all the other glands. It has three parts: This is the master gland. It controls the action of all the other glands. It has three parts: Anterior lobe-makes 6 hormones. One controls body growth and hormones that control the growth and function of the gonads Anterior lobe-makes 6 hormones. One controls body growth and hormones that control the growth and function of the gonads Intermediate lobe-secretes a hormone that controls the darkening of skin Intermediate lobe-secretes a hormone that controls the darkening of skin Posterior lobe- secretes a hormone that controls the balance of water in the body Posterior lobe- secretes a hormone that controls the balance of water in the body

6. Adrenal Glands These are glans that help the body recover from stress and react to emergencies. They have two parts These are glans that help the body recover from stress and react to emergencies. They have two parts Adrenal cortex-secretes hormones that affect sodium levels, blood pressure, metabolism, and immunity Adrenal cortex-secretes hormones that affect sodium levels, blood pressure, metabolism, and immunity Adrenal medulla-secretes adrenaline Adrenal medulla-secretes adrenaline

7. Thyroid Gland- makes hormones that controls metabolism, body heat, and bone growth Thyroid Gland- makes hormones that controls metabolism, body heat, and bone growth Testes- male reproductive glands Testes- male reproductive glands Ovaries-female reproductive gland Ovaries-female reproductive gland Pineal gland- secretes melatonin. This controls sleep cycles and affects the onset of puberty Pineal gland- secretes melatonin. This controls sleep cycles and affects the onset of puberty Endocrine System continued

8. Diabetes mellitus- when the pancreas does not make enough insulin. It may cause high glucose levels. You have to urinate often. It may cause fatigue, loss of weight and thirst. Diabetes mellitus- when the pancreas does not make enough insulin. It may cause high glucose levels. You have to urinate often. It may cause fatigue, loss of weight and thirst. Graves’ disease- this is when the thyroid makes too much thyroxin. It may cause you to feel nervous an have rapid weight loss, rapid heart rate, and thirst Graves’ disease- this is when the thyroid makes too much thyroxin. It may cause you to feel nervous an have rapid weight loss, rapid heart rate, and thirst Cushing’s Disease- a result of too many adrenal hormones. It may cause you to have a round face, a hump on you lower back, thin skin, and fragile bones. Cushing’s Disease- a result of too many adrenal hormones.
