Major functions of the Endocrine System
All living organisms are made up of -Glands
Emotions and mood.
Growth and development.
Fertility and sexual function.
Metabolism (the way you break down food and get energy from nutrients).
Blood pressure.
Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.
Diseases Associated with the Endocrine System
Addison disease
fatigue
weight loss
abdominal pain
low blood sugar
nausea or vomiting
diarrhea
irritability
a craving for salt or salty foods
irregular period
Diabetes
fatigue
weight loss
increased hunger or thirst
frequent urge to urinate
irritability
frequent infections
Homeostatic mechanisms of hormone regulation (negative and positive feedback)
Most hormones are controlled by negative feedback, in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme.
Compare and contrast steroid vs. non-steroid hormones and list the hormones for each
category
Hormones fall into two general groups—steroid and nonsteroid hormones. Each type of hormone acts on a target cell in a different way. Steroid hormones are produced from a lipid called cholesterol. Nonsteroid hormones include proteins, small peptides, and modified amino acids.
Steroid hormones are derived from cholesterol and are lipid-soluble molecules. Hormones are released into the blood and travel to other parts of the body where they bring about specific responses from specific cells.
Major endocrine glands/organs and their functions (separate by region/ body cavity)
Pineal. This gland is found in the middle of your brain. It’s important for your sleep-wake cycles.
Thyroid. The thyroid gland is located in the front part of your neck. It’s very important for metabolism.
Pituitary. The pituitary gland is located below the hypothalamus. The hormones it produces affect growth and reproduction. They can also control the function of other endocrine glands.
Parathyroid. Also located in the front of your neck, the parathyroid gland is important for maintaining control of calcium levels in your bones and blood.
Hypothalamus. While some people don’t consider it a gland, the hypothalamus produces multiple hormones that control the pituitary gland. It’s also involved in regulating many functions, including sleep-wake cycles, body temperature, and appetite. It can also regulate the function of other endocrine glands.
Thymus. Located in the upper torso, the thymus is active until puberty and produces hormones important for the development of a type of white blood cell called a T cell.
Adrenal. One adrenal gland can be found on top of each kidney. These glands produce hormones important for regulating functions such as blood pressure, heart rate, and stress response.
Pancreas. The pancreas is located in your abdomen behind your stomach. Its endocrine function involves controlling blood sugar levels.
