Hormones Flashcards
What does the Hypothalamus release?
2
Oxytocin & Anti Diuretic Hormone
What does the posterior pituitary release?
ADH
Oxytocin
Where are the target cells for ADH and what is their effect?
Kidneys & Sweat Glands
Water Balance
Where are the target cells for Oxytocin and what is their effect?
Female Reproductive System
Stimulates uterine contractions in a female
What are the transport systems for the hormones from the hypothalamus to the Pituitary Glands?
Posterior - Through the median eminence and nervous system
Anterior - Portal vessels
What are the Hypothalamus Releasing Hormones and their corresponding Pituitary Hormones?
GnRH - LH
GnRH - FSH
Thyroid Releasing Hormone - Thyroid Stimulating Hormone
PRH - Prolactin
GHRH - Growth Hormone
Corticotropin Releasing Hormone - Adrenocorticotropic hormone
Where are the target cells for LH and what is their effect?
Reproductive system
Stimulates production of sex hormones
Where are the target cells for FSH and what is their effect?
Reproductive system
Stimulates production of Sperm & Eggs
Where are the target cells for TSH and what is their effect?
Thyroid Gland
Stimulates release of:
- T3 (Triiodothyronine)
- T4 (Thyroxine)
Both increase metabolic rate
Where are the target cells for PRL and what is their effect?
Mammary Glands
Production of Milk
Where are the target cells for GH and what is their effect?
Liver, Bone & Muscles
Promotes the production of IGFs which stimulates growth & metabolic rate
Where are the target cells for ACTH and what is their effect?
Adrenal Glands
Increases the production of gluticosteroids
Where are the target cells for Parathroid Hormone and what is their effect?
Kidneys, Bone Intestine
Regulates blood calcium
