Endocrine System
| Question | Answer |
|---|---|
| What is Target tissue | Cells which respond to the presence of a particular hormone. |
| What are some specific endocrine glands | Pituitary, Thyroid Parathyroid Adrenal Pancreas Ovaries & Testes Thymus Pineal |
| What system does the endocrine system functions with | Nervous System |
| What are some of the main functions of the endocrine system? | Water balance, uterine contractions and milk release, growth, metabolism and tissue maturation, Ion regulation (Na+, K+,Ca++ in the blood), Heart rate & blood pressure, Immune System-production of immune cells, and reproductive functions |
| Hormone secretion is regulated by? | A. Blood levels of chemicals (insulin) B. Hormones ( pituitary act on ovaries) C. Nervous System (Epinephrine released from adrenal glands) |
| What is a small pea-sized gland that is known as the master gland and releases 8 different hormones? | Pituitary Gland (hypophysis) |
| This is located inferior to the thalamus and is attached to the pituitary gland? | Hypothalamus |
| This is attached to the hypothalamus by a network of blood vessels which sends 6 different "releasing hormones" via the hypothalamus which can be released when the need arises | The Anterior Pituitary Gland |
| This hormone is attached to the hypothalamus by neurons, which synthesizes two hormones and passes them into this gland for storage temporarily | Posterior Pituitary Gland |
| What are the 6 Anterior Pituitary Hormones | GH (growth hormone), Prolactin, Thyroid Stimulation Hormone (TSH), Adrenocorticotropic Hormone, Follicle Stimulation Hormone (FSH), Luteinizing Hormone (LH) |
| What are the 2 Posterior Pituitary Hormones | Oxytocin, and Antiduretic hormone |
| Which hormone releases calcitonin which inhibits calcium and phosphate salts to be deposited into the bones to reach homeostasis | Thyroid Gland |
| This hormone will withdraw calcium and phosphate salts to be withdrawn from the bones and put into blood to reach homeostasis | Parathyroid gland |
| Which gland secretes Norepinephrine and Epinephrine hormones causing increase B/P, increase heart rate, etc | Adrenal Gland |
| Which gland uses insulin and glucagon to decrease blood glucose by transporting glucose into the cell and out of the blood. | Pancreas |
| Which gland secretes estrogen and progesterone | Ovaries |
| Which gland secretes testosterone | Testes |
| Which gland produces thymosin and affects T cell production of the immune system | Thymus Gland |
| Which gland produces melatonin and regulates the onset of puberty | Pineal Gland |
