Endocrine Flashcards
Master gland of the endocrine system
Pituitary Gland
Produces growth hormone, prolactin, and addrenocoriticotropic hormone
Pituitary Gland
Produces Thyroxin and Calcitonin
Thyroid Gland
Helps to regulate metabolism
Thyroid Gland
Help to regulate calcium levels in the blood
Calcitonin
Produces parathyroid hormone
Parathyroid Gland
Helps to regulate calcium levels in the blood (2)
Parathyroid Gland
Produces thymosin
Thymus Gland
Helps to develop the immune system
Thymosin
Produces epinephrine and norepinephrine, which helps to regulate the fight or flight response
Adrenal Gland
Produces insulin and glucagon
Pancreas
Helps to regulate blood sugar levels
Insulin and Glucagon
Produce estrogen and progesterone, which helps to regulate the menstrual cycle
Ovaries
Produce testosterone which helps to regulate the development of male reproductive organs and secondary sex characteristics
Testes
Hormones play a role in regulating ____ and ______
Growth and Development
Hormones play a role in regulating ______
Metabolism
Hormones play a role in ______ and ____
Reproduction and Mood
Made of cholesterol and include testosterone and estrogen
Lipid-Based Hormones
Hormones are insoluble in water and are transported in the blood by carrier proteins
Lipid-Based Hormones & Nonpolar, Fat-Soluble Hormones
Made of amino acids and include thyroid hormones
Nonpolar, Fat-Soluble Hormones
Made of amino acids and include epinephrine
Water-Soluble Hormones
Hormones are soluble in water and are transported in the blood by diffusion
Water-Soluble Hormones
Growth hormones helps stimulate
Cell division and Bone Growth
Process that amplifies change in a given direction
Positive Feedback Mechanism
Process that reverses the change or slows it down
Negative Feedback Reaction
Growth and Development, Reproduction, Metabolism, and Mood
Homeostasis in Endocrine System
Release of oxytocin during childbirth
Positive Feedback Mechanism
Causes uterine contractions and causes the fetus to push against/stretch the cervix
Oxytocin
Release of insulin in response to HIGH blood sugar levels
Negative Response Mechanism
Able to adjust the amount of hormones that is secreted in proportion to the amount of blood glucose detected in the blood
Pancreas
