- The sarcoplasmic reticulum is the endoplasmic reticulum of the muscle cell. There are sac-like regions of the sarcoplasmic reticulum known as terminal cisternae. The terminal cisternae act as calcium storage sites. The calcium ions stored in the terminal cisternae are essential in muscle contraction.

The Stomachs Feeding a cow, in fact, involves feeding the micro-organisms in her rumen. The process of fermentation takes place in the rumen and the reticulum. Fermentation is when microorganisms convert carbohydrates into volatile fatty acids and gases. This process allows the cow to convert cellulosic fiber into energy.

The Healthy Cow A thermometer is an extremely useful and inexpensive piece of equipment for cattle keepers. The cow should be adequately restrained using a crush, the thermometer inserted into the rectum and pressed up against the mucosa (lining) of the rectum. The normal temperature of an adult cow is around 38.5°C (approx 101.5°F.A temperature over 39.5°C (103°F) may indicate an infectious or inflammatory process.he cow should be adequately restrained using a crush, the thermometer inserted into the rectum and pressed up against the mucosa (lining) of the rectum.

Nutrition and Feeding of the Cow-Calf Herd: Digestive System of the Cow The reticulum, with its honeycomb like lining, is a compartment of the stomach that is involved with rumination. It also acts as a trap for foreign objects ingested by the cow. It is not unusual to find rocks, nails, and pieces of wire and metal in the reticulum of cattle.

The Female Reproductive System in Cow, Sow, Ewe, Mare and Doe The female reproductive system, as illustrates for the cow in Figure 2-1,consists of two ovarians and the female duct system. The duct system includes the oviducts,uterus,cervix,vagina,and vulva. The origin of the ovaries is the secondary sex cords of the genital ridge.agina. The vagina is tubular in shape,thin-walled and quite elastic.It is from 25 to 30 cm in length in the cow and mare,and 10 to 15 cm in length in the sow, doe, and ewe. In the cow, doe ,and ewe, semen is deposited into the anterior end of the vagina,near the opening to the cervix, during natural mating.

The Rough Endoplasmic Reticulum (rER) The Rough Endoplasmic Reticulum (rER) The rER is a series of stacked membranes closest to the nucleus that is the site for synthesis and maturation of proteins destined for the plasma membrane, secretory vesicles, or endocytic vesicles. Many ribosomes stud the cytoplasmic face of the rER, as well as populating the surrounding cytoplasm.

Does a Cow Recover From a Prolapse? A cow can suffer from several forms of prolapse, including vaginal, uterine or rectal. A prolapse occurs when tubal tissue turns inside out and hangs out of the body. prolapse is recognizable by the appearance of pink tissue protruding from the rear end of the cow, below the tail. Because this mass of uterine, vaginal or rectal tissue is outside of the body when it normally would be inside the body, a variety of issues can result.
