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.
Mucosal-associated Lymphoid Tissue (MALT) refers to the unencapsulated lymphoid tissue distributed in association with mucosal tissues, primarily within their lamina propria. Histology The key feature of MALT is its presence in the mucosal lamina propria and its unencapsulated nature. MALT can appear as aggregations of immune cells roughly similar in architecture to a section of a lymph node and may contain lymphoid follicles with germinal centers. Unlike lymph nodes, MALT aggregations are not penetrated by lymphatic vessels and are exposed to antigens directly from the mucosa they surround. In addition, MALT refers to the diffusely distributed immune cells, usually lymphocytes, found throughout the lamina propria of mucosa. Function Given the enormous microbial burden present at mucosal surfaces, MALT provides the immune system easy histological access to the organisms.
