As well as using eye drops, dry eyes can be helped by taking a supplement of omega 3,6 and 9. Sjogrenâs syndrome: An auto-immune condition affecting around half a million people in the UK, this causes the body to attack its own moisture-producing glands, leading to abnormal dryness of the eyes, says Mr Allamby.
The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1).
Endoplasmic reticulum is a system of tubules. If there are ribosomes on the tubules, it is termed rough endoplasmic reticulum. Ribosomes produce proteins. When the ribosomes are attached to endoplasmic reticulum, the proteins produced by the ribosomes are exported.
