Trophic hormone is a hormone that has a growth effect, hyperplasia or hypertrophy, on the tissue it is stimulating. The term ''trophic'' is from Ancient Greek τροφικός (''trophikós'') meaning "pertaining to food or nourishment", here used to mean "growth"; this is the same origin as ''atrophy.'' This should not be confused with ''tropic,'' as in the similar-sounding tropic hormone – the words and concepts are both unrelated. A key example of this is thyroid-stimulating hormone stimulating the thyroid; excess thyroid-stimulating hormone can create a goitre. Trophic hormones from the anterior pituitary include: *Thyroid-stimulating hormone (TSH or thyrotropin) – stimulates the thyroid gland increasing the size and number of cells. *Adrenocorticotropic hormone (ACTH or corticotropin) – stimulates the adrenal cortex increasing the size and number of cells. ==See also== *Endocrine system *Tropic hormone *Non-tropic hormone 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trophic hormone」の詳細全文を読む スポンサード リンク
