Lesson 24.1.2 Hormones Flashcards
Melatonin
(Pineal Gland) Melatonin is the hormone that regulates the sleep-wake cycle. It also controls reproductive cycles and beginning of puberty. [The circadian rhythm or “biological clock”]
Gonadotropin- releasing hormone (GnRH)
(Hypothalamus) stimulates the release of hormones connected to puberty, sexual maturation, and reproductive function.
Somatostatin
(Hypothalamus) causes the pituitary gland to stop the release of growth hormone.
Growth hormone
(Pituitary gland) is for bone and tissue growth. [anterior lobe]
Thyroid-stimulating hormone (TSH)
(Pituitary gland) is for stimulating the thyroid gland. [anterior lobe]
Adrenocorticotropic hormone (ACTH)
(Pituitary gland) stimulates the adrenal gland. [anterior lobe]
Prolactin
(Pituitary gland) regulates milk production in females. [anterior lobe]
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
(Pituitary gland) control sexual functions. [anterior lobe]
Antidiuretic hormone (vasopressin)
(Pituitary gland) controls water loss. [posterior lobe]
Oxytocin
(Pituitary gland) stimulates uterine contractions during childbirth. [posterior lobe]
Thyroxine
(Thyroid gland) is a hormone used to regulate metabolism. It plays a crucial role in digestion, muscle control, and bone development.
Parathyroid Hormone
(Parathyroid gland) to regulate the blood calcium levels and bone metabolism.
Corticosteroids
(Adrenal gland) regulate metabolism, salt balance, and the immune system. [cortex]
Catecholamines
(Adrenal gland) help the body cope with different kinds of stress. [medulla]
Epinephrine or Adrenaline
(Adrenal gland) released during stress or strenuous activities. They control the fight-or-flight response (increase blood flow to muscles, pupil dilation, and blood sugar). [medulla]
