ANATOMY

Detailed explanation-1: -Whereas Oxytocin and vasopressin, two peptide hormones, are actually synthesized in the hypothalamus and then transported axonally to the posterior pituitary gland . So, hypothalamus does not produce any releasing hormone for pituitary to release oxytocin.

Detailed explanation-2: -A hormone made by a part of the brain called the hypothalamus. Gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Detailed explanation-3: -The hypothalamus produces GnRH, and it is released into the hypophyseal portal circulation to act on G-protein-coupled receptors at gonadotropic cells of the anterior pituitary. Those gonadotropic cells produce FSH and luteinizing hormone (LH) and release them into the peripheral circulation.

Detailed explanation-4: -The hormones produced in the hypothalamus are corticotrophin-releasing hormone, dopamine, growth hormone-releasing hormone, somatostatin, gonadotrophin-releasing hormone and thyrotrophin-releasing hormone.

Detailed explanation-5: -For each system, the hypothalamus secretes releasing hormones (i.e., CRH, GnRH, and TRH) that act on the pituitary gland. In response to those stimuli, the pituitary gland releases ACTH, gonadotropins (i.e., LH and FSH), or TSH.
