Question | Answer |

What 2 systems control the activity of the body | 1. Nervous System 2. Endocrine System These 2 systems work together to regulate the activity of body cells |
What are the Nervous & Endocrine System regulated by? | 1. Nervous - nerve impulses (electrochemical) 2. Endocrine - chemical messengers called HORMONES |
What is the difference between exocrine & endocrine ducts? | Exocrine has ducts Endocrine has NO DUCTS |
Name the 2 major types of Hormones | 1. Protein Hormone 2. Steroid Hormone |
List the 2 second messengers | 1. Cyclic AMP 2. PIP (calcium signal mechanism) |
Describe Protein Hormones | - are NOT fat soluble - require a 2nd messenger to regulate their target tissue cells |
Describe Steroid Hormones | - Are fat soluble - can pass through cell membranes - DO NOT require a 2nd messenger go directly to the nucleus & activate the specific gene on the chromosomes |
Where is the Pituitary Gland located | - lies under surface of the brain - lies beneath the hypothalamus of the brain |
what is the stalk-like structure that is connected to the hypothalamus | Infundibulum |
Where does the Pituitary Gland sit in the brain | sella tursica |
What are the 2 distinct regions of the Pituitary Gland | 1. Anterior Pituitary 2. Posterior Pituitary |
What is the link between the nervous and endocrine system | Hypothalamus |
What is the difference between Anterior and Posterior Pituitary | - they are seperate glands - they produce different hormones - have different control mechanisms - have embryonic origins |
What is the pituitary gland called | Master Gland |
What is the pituitary gland controlled by | hypothalamus of the brain |
List the Anterior Pituitary Hormones | 1. Growth Hormone (GH) 2. Prolactin 3. Thyroid Stimulating Hormone (TSH) 4. Adrenocorticotropic Hormone (ACTH) 5. Follicle Stimulating Hormone (FSH) 6. Luteinizing Hormone (LH) |
What are Tropic Hormones | hormones that regulate another endocrine gland |
List the 4 Tropic Hormones | 1. Thyroid-Stimulating Hormone (TSH) 2. Adrenocorticotropic Hormone (ACTH) 3. Follicle-Stimulating Hormone (FSH) 4. Luteinizing Hormone (LH) |
What is the function of Thyroid Stimulating Hormone (TSH) | Stimulating the thyroid gland |
What is the function of Adrenocorticotropic Hormone (ACTH) | stimulates the Adrenal Cortex of the Adrenal Gland |
What is the function of Follicle Stimulating Hormone (FSH) | helps regulate production of the ovaries and testes |
Ovaries and Testes are called | Gonads |
FSH & LH are called ____. What will they regulate | Gonadotropin Gonads |
