Oxytocin
Oxytocin is a mammalian neurohypophysial hormone produced by hypothalamus and stored and secreted by posterior lobe of pituitary gland. It acts as a neuromodulator in the brain. It is secreted by the pituitary without the involvement of a Releasing Hormone (RH).
TSH, FSH and prolactin are secreted with the involvement of releasing hormones to release thyrotroph, gonadotroph and lactotroph cells triggers respectively the anterior lobe of pituitary to release their particular hormones such as thyroid releasing hormone, gonadotropin releasing hormone and prolactin releasing hormone, respectively.
