Hypothalamus is a bridge between the nervous system and endocrine system

Endocrine system secretions start in the brain.

Hypothalamus controls what is released by the pituitary gland by secreting releasing factors.

• Thyrotropin releasing hormone = TRH

• Corticotropin releasing hormone = CRH

• Gonadotropin releasing hormone = GRH

• Growth hormone releasing hormone = GHRH

Releasing hormones from the hypothalamus cause the release of stimulating hormones from the pituitary.

-Thyroid stimulating hormone TSH

-Adrenocorticotropic hormone ACTH

-Follicle stimulating hormone FSH-Luteinizing hormone LH

-Growth hormone GH

What do the following pituitary gland hormone do? TSH, ACTH, FSH, LH, GH
