The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus Author: Charles Molnar, Jane Gair, Molnar, Charles, Gair, Jane. CHAPTER 15 • THE FEMALE REPRODUCTIVE SYSTEM; PREGNANCY AND BIRTH The Mammary Glands The mammary glands, or breasts, are composed mainly of glandular tissue and fat (Fig. ). Their purpose is to provide nourishment for the newborn. The milk secreted by the glands is carried in ducts to the nipple. The Menstrual CycleFile Size: 1MB.
FIGURE(S): Female Tubular Genitalia The cervix lies between the uterine body and the vaginal vault where it acts as a barrier during certain phases of the estrus cycle and during pregnancy. The mucosa of the cervix is thrown up in longitudinal folds Author: Ryan Jennings, Christopher Premanandan. The Golgi Apparatus. The Golgi apparatus is responsible for sorting, modifying, and shipping off the products that come from the rough ER, much like a post-office. The Golgi apparatus looks like stacked flattened discs, almost like stacks of oddly shaped pancakes. Like the ER, these discs are membranous. The Golgi apparatus has two distinct.

It lies below the brain in a cavity of the sphenoid bone—the sella turcica (Figure 20–2). The pituitary develops in the embryo partly from oral ectoderm and partly from the developing brain (Figure 20–3).

Studies on the Golgi Apparatus in Gland-cells. Glands associated with the Alimentary Tract. By Robert H. Bowen, Department of Zoology, Columbia University. With Plates THE recent researches of Nassonov ( and ) on the relation of secretory granules to the Golgi apparatus have again revived the hope that we may at last be on the Cited by: 8.
Considering the Golgi apparatus from the standpoint of its general behaviour in gland-cells, perhaps the most striking feature which it constantly presents is the increase in its amount during secretory activity. This hypertrophy of the Golgi apparatus occurs in every type of gland-cell which I have examined, and has been commented upon by.

One of the secreted glycoproteins, uteroferrin, is believed to play an important role in the iron transfer from mother to fetus. From midpregnancy onward, a special cell type, the “granule laden cell” is found scattered between normal secretory cells of the uterine by: Uterine epithelial cells contained agranular ER and a well-developed Golgi apparatus.

Free ebooks since We previously reported that at 6 weeks gestational age the glandular epithelial cells closely resemble those during the luteal phase of the cycle, with large accumulations of glycogen within the apical portions of the cell [18,21]. In the normal menstrual cycle these accumulations disperse around days 23–24, but their persistence indicates that the corpus luteum of pregnancy maintains the glands Cited by: In rats, there is a documented increase in cytoplasmic organelles (e.g., the number of Golgi bodies and dense-core vesicles) in the second half of the pregnancy.

Physiology of Lactation. of the cell biology and physiology of milk formation well-developed Golgi apparatus, and secretory vesi- lar epithelial cells during pregnancy.
Milk secretion involves significant flux of water, driven largely by synthesis of lactose within the Golgi apparatus. It has not been determined whether this flux is simply a passive consequence of the osmotic potential between cytosol and Golgi, or whether it involves regulated flow.
Aquaporins (AQPs) are membrane water channels that regulate water flux. AQP1, AQP3 and AQP5 have previously Cited by: 4. The lining epithelial cells of alveoli differentiate into active secretory cells with prominent rough endoplasmic reticulum, Golgi apparatus and numerous mitochondria.
The growth during pregnancy is affected by many factors, in the first place by hormones – estrogens, progesterones, prolactin, human chorionic gonadotropin – hCG.
The size of the milk gland reaches its maximum during the peak of milk production, when cells are filled with endoplasmic reticulum, Golgi apparatus, mitochondria, and the milk gland vacuole is fully replete (Fig 1B).
The milk gland quickly returns to its pre-lactation state within one day of parturition, following the proliferation of Cited by: 1. The development of the placenta begins during implantation of the blastocyst. The cell blastocyst contains two distinct differentiated embryonic cell types: the outer trophoblast cells and the inner cell mass.
The trophoblast cells form the placenta. The inner cell mass forms the fetus and fetal membranes/5. Uterine natural killer cells make up approximately 70% of maternal lymphocytes during pregnancy, occupying both the decidua basalis of the endometrium at the implantation site and the mesometrial lymphoid aggregate of pregnancy that surrounds the blood vessels supplying the placenta.
This number is at its peak in early pregnancy but declines at parturition. Human endometrial glands synthesize and secrete a high molecular weight mucin-like glycoprotein in a menstrual cycle-dependent fashion.
A novel moiety within this Golgi-associated glycoprotein is strongly reactive with IgG antibodies in numerous murine ascites, and has been termed MAG (mouse ascites Golgi).Cited by: Placental concentration Pulsatile Shows diurnal variations During pregnancy – start at 8th week & peak ( ng/ml) at term Sources – placenta, amniotic fluid & maternal anterior pituitary gland.

Uterine closure involves mild generalised oedema and reabsorption of luminal on: Epithelium. After implantation, during mid-gestation and during prepartum luteolysis, a similar localization pattern was seen for both receptors in the uterine parts of the uteroplacental compartments (i.e., superficial uterine glands, the so-called glandular chambers) and deep uterine glands (Figs.
