Thyroid Gland and other key Hormones Flashcards
What hormones are produced by the thyroid gland?
Thyroid hormone (TH), thyroxine (T4), triiodothyronine (T3), and calcitonin
How are thyroid hormones released
The hypothalamus releases a neurotransmitter that promotes TSH release from the anterior pituitary, which then stimulates T3 and T4 release from the thyroid.
What are the main functions of T3 and T4?
They increase basal metabolic rate, body temperature, and help maintain heart and blood pressure.
What triggers calcitonin release, and what is its function?
Calcitonin is released in response to high blood calcium levels and regulates circulating calcium and phosphate through bone metabolism
What are the main functions of oxytocin?
Oxytocin induces labor contractions and promotes milk ejection.
What is the role of ADH (vasopressin)?
ADH promotes water reabsorption in the kidneys, helping to concentrate urine
How does Gonadotropin-Releasing Hormone (GnRH) function
GnRH from the hypothalamus promotes LH and FSH release from gonadotropin cells, affecting gonadal function
What do Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) regulate
FSH and LH regulate oocyte and sperm production.
: What are the main functions of Growth Hormone (GH)?
GH is an anabolic hormone with tissue-building, metabolic, and growth-promoting effects.
What is the role of Thyroid Stimulating Hormone (TSH
TSH promotes normal thyroid gland development and hormone secretion.
What is the function of prolactin?
Prolactin stimulates milk production
How does Adrenocorticotropic Hormone (ACTH) function
ACTH promotes corticosteroid release from the adrenal glands
