Study Questions (Part Eight- Endocrine) Flashcards
The Posterior Pituitary Gland produces what?
Oxytocin (OT) Antidiuretic Hormone (ADH, vasopressin)
Oxytocin (OT) targets which organ?
Reproductive organs
Antidiuretic Hormone (ADH, vasopressin) targets which organ?
Kidneys
What is the function of Oxytocin (OT)?
In females oxytocin produces a contraction of the uterus and promotes the ejaculation of milk.
Oxytocin is also a bonding hormone that produces a desire to cuddle, groom, and bond with mate.
What is the function of Antidiuretic Hormone (ADH, vasopressin)?
ADH promotes the reabsorption of water and concentrates urine. It is chemically similar to oxytocin and can create crossover reactions.
The Anterior Pituitary Gland produces what?
Somatotrophins (Growth Hormones GH or HGH) Thyroid Stimulating Hormone (TSH) Adrenocorticotropic Hormone (ACTH) Prolactin (PRL) Lutenizing Hormone (LH) Follicle Stimulating Hormone (FSH)
GH/HGH (Somatotrophins) target which organ?
The liver
TSH (Thyroid Stimulating Hormone) targets which organ?
The thyroid
ACTH (Adrenocorticotropic Hormone) targets which organ?
The Adrenal Cortex
PRL (Prolactin) targets which organ?
The breasts
LH (Lutenizing Hormone) targets which organ?
The gonads
FSH (Follicle Stimulating Hormone) targets which organ?
The gonads
What is the function of GH/HGH (Somatotrophins)?
GH/HGH stimulates growth, cellular reproduction, and regeneration.
It affects the height and length of bones.
What is the function of TSH (Thyroid Stimulating Hormone)?
Stimulates the thyroid to release thyroxin (important for metabolism).
What is the function of ACTH (Adrenocorticotropic Hormone)?
Signals the adrenal cortex to secrete glucocorticoids (important for the management of stress).
What is the function of PRL (Prolactin)?
Milk production.
If not lactating, high levels are often due to a pituitary tumor.
What is the function of LH (Lutenizing Hormone)?
Maturation of sex cells.
In females, that mean ovulation; in males, it means the secretion of androgens.
What is the function of FSH (Follicle Stimulating Hormone)?
Maturation of sex cells.
In females that means the maturation of ova, and the secretion of androgens, estrogen, and progesterone. In males, that means the maturation of sperm and the production of androgen binding protein.
