ENDOCRINE SYSTEM

OBJECTIVES:

2. The scholars will differentiate between hormones and enzymes.
3. The scholars will be able to explain the negative feedback loop in regards to hormones.
4. The scholars will be able to locate the major endocrine glands, identify the hormones the glands produce and the effect on body systems.
5. The scholars will differentiate between Type I and Type II Diabetes, be able to discuss the effect on our health care systems, and be able to give first aid for under/over insulin levels

DEFINITIONS:

Endocrine Gland: are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.

Exocrine Gland: a gland (as a sweat gland, a salivary gland, or a kidney) that releases a secretion external to or at the surface of an organ by means of a canal or duct—called also gland of external secretion.

Hormone: a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.

Enzyme: a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.

Negative Feedback loop: the process in which part of the output of a system is returned to its input in order to regulate its further output

Analyze the following glands and answer the prompts (in complete sentences) associated with each gland. DO NOT COPY AND PASTE OFF OF THE INTERNET THIS WILL RESULT IN A ZERO.

PITUITARY GLAND

Location: It is located in the bottom of the hypothalamus at the base of the brain.

Main hormones: The main hormone is cortisol.

Acromegaly: In acromegaly, the pituitary produces excessive amounts of GH.

Gigantism: A pituitary gland tumor is almost always the cause of gigantism.

Dwarfism: is a condition in which the pituitary gland does not make enough growth hormone, resulting in a child's slow growth pattern.

THYROID GLAND

Location: sits low on the front of the neck

Requires: The nutrients our thyroid needs are easily accessible in many foods and dietary supplements.

Hormone: T3 (triiodothyronine) and T4 (thyroxine) are the two main hormones.

Hyperthyroidism: is a condition in which the thyroid gland is overactive and makes excessive amounts of thyroid hormone.

Hypothyroidism: the thyroid gland does not make enough thyroid hormone.

PARATHYROID GLANDS

Location: are located in the neck behind the thyroid

Hormone: Parathyroid Hormone is a hormone for Parathyroid glands. PTH regulates how much calcium is absorbed from your diet, how much calcium is excreted by your kidneys, and how much calcium is stored in your bones.

Hyperparathyroidism: when your parathyroid glands overproduce parathyroid hormone.

Hypoparathyroidism: is decreased function of the parathyroid glands with underproduction of parathyroid hormone.

ADRENAL GLANDS

Location: They are located on top of each kidney.

Hormones: Mineralocorticoids, Glucocorticoids, and Adrenal androgens.

Cortex: The outer portion of the gland is called the adrenal cortex.

Medulla: the inner part of the adrenal gland helps a person cope with physical and emotional stress.

THYMUS

Location: in the upper anterior (front) part of your chest directly behind your sternum and between your lungs.

Functions: The thymus gland, despite containing glandular tissue and producing several hormones, is much more closely associated with the immune system than with the endocrine system.

Hormones: hormone of the thymus and it stimulates the development of disease-fighting T cells.

PINEAL BODY

Location: is a small pinecone-shaped mass of glandular tissue found just posterior to the thalamus of the brain.

Function: the pineal gland also regulates other endocrine functions and converts signals from the nervous system into endocrine signals.

Hormones: The pineal gland produces the hormone melatonin that
