Bacteria and viruses can infect the conjunctiva. Redness and tearing or discharge are common symptoms, and some people have sensitivity to light. Good hygiene helps prevent the infection from spreading to the other eye or to someone else's eye. Antibiotic eye drops are often given.
Cartilage and Adipose. Cartilage. Cartilage is a specialized connective tissue that provides for both strength and flexibility. It is mainly found in the form of hyaline cartilage (hyalos means glass in Greek), which is so named because of its smooth, glassy bluish-white appearance when fresh.
In connective tissue proper, the intercellular substance is soft, in cartilage it is firm yet flexible, in bone it is rigid due to the deposition of calcium salts, in blood it is fluid. Connective tissue in the embryo has quite a different structure and consistency from that in the adult. Knowledge of the development of the connective tissues is important, for the stages of repair in wound healing have considerable similarity to embryonic developmental stages.
