Endocrine Video Assignment

Endocrine Video Assignment – DUE June 28 at noon via email – 25 points

1. What are tropic hormones and how do they work? Use an example based on the pituitary hormones in your explanation. (Examples: TSH, ACTH, FSH & LH)

Tropic hormones target other endocrine glands. TSH is thyroid stimulating hormone and it stimulates the thyroid gland to release thyroid hormones.

2. What hormones stimulate overall growth and an increase in metabolic activities of the body?

Growth hormones promote overall growth.

3. Electrolytes are ions floating in the blood plasma, and include sodium, potassium, calcium, etc. What hormones are released by the endocrine system to balance these electrolytes?

ADH is antidiretic hormone that is released from the pituitary gland when the blood solute is increased. ADH acts on the kidney to reabsorb water to balance electrolyes.

4. Explain how the adrenal gland works as both a sympathetic ganglion and an endocrine organ? What materials are produced to help with the stress response?

The adrenal gland works as a sympathetic ganglion when it is stimulated in an fight or flight response by releasing Catecholamines. The adrenal gland acts as an endrocrine organ when it is stimulated by ACTH.

5. What essential hormones are released from the pancreas? What cells produce them and what action does the hormones’ release cause in the body?

The pancreas releases insulin and glucagon to lower and raise the blood glucose. The insulin is produced in the pancreas by Beta Cells and the Glucagon is produced in the pancreas by the alpha cells. When the blood glucose rises the pancreas release insulin which stimulates tissues and cells to take up glucose. Insulin also acts on the liver, stimulating it to convert glucose to glucogon. Thus, decreaseing the blood glucose. Glucagon has an opposite effect. When blood glucose levels fall the pancreas releases Glucagon that stimulates the liver to convert glucagon to glucose.
