Complete the following chart Control of Release Hormone Specific Source obytocin Neurosecretory cells of the posterior pinitory Nerve impulses traveling from hypothalamus toposterior pituitary T, and T. Epinephrine ProlactinExplanation / Answer
Answer:
1. a. Diabetes mellitus:
Gland: Pancreas
Hormone: Insulin
Diabetes incipidus:
Gland: Pituitary gland
Hormone: Vasopressin
In case of diabetes milletus, there is increase in blood glucose level or hyperglycemia, while there is no rise in blood sugar level in diabetes incipidus.
b. Cushing syndrome:
Gland: Pituitary gland
Hormone: Adrenocorticotropic hormone (ACTH)
Addison's disease:
Gland: Adrenal glands
Hormone: Cortisol (Aldosterone in some cases)
Cushing disease is caused by a pituitary gland tumor (usually benign) that over-secretes the hormone ACTH, thus overstimulating the adrenal glands' cortisol production.
Addison disease is a condition caused by damage or destruction of the adrenal cortex. This damage leads to lack of cortisol and other adrenal steroids.
c. Hypothyroidism:
Gland: Pituitary gland, Thyroid hormone
Hormone: Thyroid-stimulating hormone (TSH), Thyroxine
Hyperthyroidism:
Gland: Pituitary gland, Thyroid gland
Hormone: Thyroid-stimulating hormone (TSH), Thyroid hormone (Triiodothyronine and thyroxine)
Hypothyroidism is the reduced activity of the thyroid gland (underactive thyroid) leading to a decrease in circulating thyroid hormones. This slows the metabolic activity within the body.
Hyperthyroidism (thyrotoxicosis) is the increased activity of the thyroid gland (overactive thyroid) resulting in an increase in the level of thyroid hormones circulating in the blood. This speeds up the metabolic activity within the body.
