One physician notes that clinical observation shows that breastfeeding contractions do not produce dilation of the cervix. Accordingly, in the Moscona survey of 57 mothers breastfeeding during pregnancy, only four women (seven percent) recalled contractions related to breastfeeding at all.
The pituitary gland itself consists of a larger anterior lobe that makes the following hormones: adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), growth hormone (GH) and Prolactin.
The pituitary gland secretes nine hormones that regulate homeostasis by stimulating other endocrine glands to produce and secrete their own hormones. The pituitary gland has two components: the anterior (front) pituitary (or adenohypophysis) and the posterior (back) pituitary (neurohypophysis).
