Step-by-Step Solution:1. Definition of Lactation: - Lactation refers to the process of milk secretion from the mammary glands of female mammals. It typically begins after childbirth and is essential for fee
In humans, there are several parts of the breast and mammary gland that play critical roles in lactation. The alveoli are responsible for producing and storing milk. A group of alveoli forms what is known as a lobule, which connects to a lobe. The lobes connect to milk ducts, which transp...
Prolactin has a rich mechanistic set of actions and signaling in order to elicit developmental effects in mammals. Historically, prolactin has been appreciated as an endocrine peptide hormone that is responsible for final, functional mammary gland development and lactation. Multiple signaling pathways ...
Although in some mammals oxytocin may also function in the control of plasma osmolality, its major role is to cause contraction of the smooth muscle in the uterus and mammary gland during birth and lactation. View chapter Chapter Gastrin Encyclopedia of Gastroenterology Reference work2004, ...
The Ovary-Brain Axisregulates production of estrogen, progesterone and testosterone (yes, women have testosterone too). It also regulates luteinizing hormone, follicle stimulating hormone and prolactin. Collectively, these hormones are responsible for ovulation, menstrual bleeding, lactation and menopause. ...

Called alsoautacoidandautocoid. luteinizing hormone(LH) agonadotropinof the anterior pituitary gland, acting withfollicle-stimulating ...
the production of CCN3 in these select neurons, lactating female mice rapidly lost bone, and their babies began to lose weight, confirming the importance of the hormone in maintaining bone health during lactation. Based on this discovery, they now refer to CCN3 as Maternal Brain Horm...
(Aß), which impairs neural function in the brain. Experimentation has shown that oxytocin, a peptide hormone primarily responsible for parturition, bonding, and lactation, also regulates cognitive behavior in the rodent central nervous system (CNS). This finding, along with the identification of ...
Although the physiological function of this placental hormone has not been established with certainty, it may be regulate maternal metabolism during pregnancy and prepare the mammary glands for lactation (Chapter 14). Growth hormone, PRL and hCS appear to have evolved from a single ancestral gene ...
In spite of the fact that the main function of PRL is lactation, it also can be an indicator of relaxation and sexual satisfaction. Increased levels of PRL decrease estrogen and testosterone and are responsible for impotence and loss of libido. PRL influences the hypothalamus, decreasing the...
