by means of IGF-I, indirectly stimulates protein anabolism and growth of bones and soft tissures. fat mobilization and glucose conservation

targets: liver

stimulates IGF-I secretion

Term
Follicule-stimulating hormone
Definition

Gland: anterior pituitary

targets: females ovarian follicles

promotes follicular growth and development; stimulates estrogen secretion

targets: males seminiferous tubules in testes

stimulates sperm production

Term
Luteinizing hormone
Definition

Gland: anterior pituitary

targets: females ovarian follicle and corpus luteum

stimulates ovulation, corpus luteum development, and estrogen and progesterone secretion

targets: males interstitial cells of leydig in testes

stimulates testosterone secretion

Term

Prolactin

 

Definition

Gland: anterior pituitary

targets: females mammary glands

promotes breast development; stimulates milk secretion

 

Term
Melatonin
Definition

Gland: Pineal Gland

targets: brain; anterior pituitary; reproductive organs; immune system; possible others

entrains body's biological rhythm with external cues. inhibits gonadotropins; reduction likely initiates pubery; acts as antioxideant; enhances immunity

Term

Tetraoidothyronine (T4)

tri-iodothyronine (T3)

Definition

Gland: thyroid gland follicular cells

targets: most cells

increases metabolic rate; essetial for normal growth and nerve development

Term
CALCITONIN
Definition

Gland: Thyroid Gland C cells

targets: Bone

Decreases plasma Ca2+ concentraion

stimulated by gastrin

Term
Aldosterone
Definition

Gland: Adrenal cortex; Zona glomerulosa

targets: kidney tubules

increases Na+ reabsorption and K+ secretion

Term
Cortisol
Definition

Gland: zona fasciculata and zona reticularis

target: most cells

increases blood glucose at the expense of protein and fat stores; contributes to stress adaption

Term
Androgens
Definition

gland: adrenal cortex; zona fasciulata and zona reticularis

females: bone and brain

responsible for pubertal growth spurt and sex drive in females

Term
Epinephrine and norepinephrine
Definition

gland: adrenal medulla

targets: sympathetic receptor sites throughout body

reinforces sympathetic nervous systen; contributes to stress adaption and blood pressure regulation

Term
insulin
Definition

Beta cells

Gland: endocrine pancreas )islet of langerhans)

targets: most cells

promotes cellulare uptake, use and storage of absorbed nutrients

Term
Glucagon
Definition

alpha cells

Gland: endocrine pancreas

targets: most cells

important for maintaining nutrient levels in blood during postabsorptive state

Term
Somatostatin
Definition

D cells

gland: endocrin pancreas

targets: digestive systen

inhibits digestion and absorption of nutrients

targets: pancreatic islet cells

inhibits secretion of all pancreatic hormones

Term
Parathyroid Hormone (PTH)
Definition

Gland: Parathyroid gland

targets: bone, kidneys, intestine

increases plasma calcium concentration; decreases plasma PO4 3- concentraion; stimulates vitamin D activation

Term
Estrogen
Definition

Gland: gonads/female ovaries

targets: female sex organs; body as a whole

promotes follicular development; governs development of secondary sexual characteristics; stimulates uterine and breast growth

targets: bone

promotes closure of the epiphyseal plate

Term

Progesterone

 

Definition

gland: gonads/ female ovaries

targets: uterus

prepares for pregnancy

 

Term

Testosterone

 

Definition

gland: male testes

targets: male sex organs; body as a whole

stimulates sperm production; governs development of secondary sexual characteristics; promotes sex drive

targets: bone

enhances pubertal growth spurtL promotes closure of the epiphyseal plate

Term

Inhibin

 

Definition

Gland: testes and ovaries

targets: anterior pituitary

inhibits secretion of follicule-stimulating hormone (FSH)

 

Term

Estrogen;progesterone

from the placenta

Definition

gland: placenta

targets: female sex organs

help maintain pregnancy; prepare breasts for lactation

Term
Human Chorionic gonadotropin
Definition

glands: placenta

target: ovarian corpus luteum

maintains corpus luteum of pregnancy

Term

Renin

(by activating angiotensin)

Definition

Gland: kidneys

target: zona glomerulosa of adrenal cortex (acten on by angiotensis, which is activated by renin)

stimulates aldosterone secretion; angiotensin II is also a potent vasoconstrictor and stiulates thirst

Term
Erythropoietin
Definition

Gland: kidneys

target: bone barrow

stimulates erythrocyte production

Term
Ghrelin
