Study Notes
- Endocrine system maintains internal stability despite external changes
- Regulates metabolism, aids in growth and development, tissue function, sexual function and reproduction, and impacts sleep and mood
- Endocrine glands secrete hormones into the bloodstream
- Hypothalamus, located at the base of the brain, controls other endocrine glands and regulates hunger, thirst, sleep, body temperature, and involuntary mechanisms
- Pituitary gland, located just below the brain, influences growth, metabolism, and regeneration, and controls all other endcrine glands
- Hormones include TSH, ACTH, FSH, LH, testosterone, estrogen, progesterone, and growth hormone
- Hormones attach to receptors within or on cells, causing changes to the cells
- Endocrine glands include the hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid glands, adrenal glands, and pancreas
- Hormones can be steroid or non-steroid, with steroid hormones made from cholesterol and non-steroid hormones being peptides or proteins
- Disorders of the pituitary gland, such as acromegaly, can lead to excessive growth hormone production and various symptoms including enlargement of body parts, high blood pressure, and abnormal production of milk.
- Treatment for pituitary disorders includes medications, surgery, and hormone replacement therapy.
Test your knowledge of the endocrine system's role in maintaining internal stability, regulating metabolism, aiding in growth and development, tissue function, sexual function, reproduction, as well as its impact on sleep and mood. Explore the functions of endocrine glands and the secretion of hormones into the bloodstream.
