| | Epithelium - Wikipedia, the free encyclopedia |
 | | Stereocilia: Similar to cilia, except they have no internal structure and are non-motile. | | | This process occurs mainly in skin, since it provides a tough, impermeable barrier. | | | Places where squamous cells can be found include the alveoli of the lungs, the filtration of the kidneys, and the major cavities of the body. |

| | Three kinds of muscle are found in vertebrates: | | | Groups of organs make up the various systems - digestive, excretory, etc. - of the body. | | | During this period, the cells produced by mitosis enter different pathways of differentiation; some becoming blood cells, some muscle cells, and so on. |

| | Epithelial Tissue |
| | Epithelial tissues come in three basic types: squamous, cuboidal and columnar. | | | This is what we commonly call "absorption." To help with this, they have numerous microvilli on their apical (lumenal) surface, which increases their surface area to allow for greater absorption. | | | The cytoplasm stains clear due to a large amount of mucus within it that the cell secretes to protect the intestinal cells from digestion by the digestive enzymes (your body wants to digest the food, not itself!). |

| | Brain tumor - Wikipedia, the free encyclopedia |
| | Tumors may affect brain cells from a distance by consuming too much food and energy that is crucial for neurons, by secreting endocrine substances altering nerve cell functions or – in the majority of the cases – by causing the immune system of the body to develop antibodies (autoantibodies) directed against nerve cells. | | | Most frequent paraneoplastic diseases are cerebellar ataxia, peripheral sensory neuropathy, limbic encephalitis and brainstem encephalitis. | | | Since the brain has no lymphatic drainage system like other organs (cerebrospinal fluid system acts like lymphatic system in the brain), spreading of tumor cells by the lymphatic route (which is very typical for cancers of other organs) is impossible in the brain. |

| | Polarized Epithelial Cells |
| | Alterations in cell membrane polarity are seen in several disease states, and may play an important role in the pathogenesis of many cancers. | | | One important example of a polarized epithelial cell is the absorptive enterocyte that lines the lumen of the lumen of the small intestine. | | | Attachments between cells are mediated by cell adhesion molecules, specifically E-cadhedin in the case of epithelial cells. |
