| Question | Answer |
|---|---|
| define histology | study of tissue |
| 4 main groups of tissues | epithelial,connective,muscle,nervous |
| epithelial tissue | covers surfaces,lines cavities, forms glands |
| connective tissue | supports and forms the framework of all parts of the body |
| mussle tissue | contracts and produces movement |
| nervous tissue | conducts nerve impulses |
| squamous | flat and irregular |
| cuboidal | square |
| columnar | long and narrow |
| transitional epithelium | capable of great expansion but returns to its original form once tension is relaxed,ex.bladder |
| goblet cells | secrete mucas, ex. pseudostratified epithelial |
| endocrine | secretes hormones directly into the blood |
| exocrine | ducts or tubes to carry secretions away from the gland |
| in connective tissue cells are seperated by large amounts of nonliving materials called | matrix |
| liquid connective tissue | suspended in a fluid enviroment, ex. blood and lymph |
| soft connective tissue | loosely held togather with semi liquid material between the cells, ex.adipose(fat)areolar(loose) |
| fibrous connective tissue | densley packed |
| fibroblast produce | ligaments,tendons,capsules |
| hard connective tissue | very firm consistency,ex. cartilage hardened by material,(bone) |
| Flexible white protein found in large numbers of fibrous connective tissue | collagen |
| some organs such as kidneys are surrounded by what | osseous tissue |
| osseous tissue | tissue of which bones r made |
| what type of cells form bones | osteoblast |
| what type of muscle tissue is voluntary | skeletal |
| dendrite | fiber carries messages in the form of nerve impulses to the nerve cell bodyaxon |
| material that insulates and protects some axons | myelin |
| what color is myelin | white |
| what are specialized cells in nerve tissue called | neuroglia |
| 3 types of epithelial membranes | serous,mucous,cutaneous |
| pleurael/pleunas | line the thoracic cavity and cover each lung |
| serious pericardium | forms part of the sac that encloses the heart |
| peritoneum | lines the walls of the abdominal cavity,covers the organs of the abdomen and forms supporting and protective structures w/in the abdomen |
| parietal layer | attached to the wall of a cavity or sac |
| visceral layer | attached to a organ |
| 2 membranes that consist of connective tissue with no epithelium | synovial membranes and menings |
| what kind of fascia covers, seperates and protects skeletal muscles | deep fascia |
| name of the cavity that encloses the heart | fibrous pericardium |
| membrane around the cartilage | perichondrium |
| in rheumatoid arthritis what membrane becomes inflamed and swollen | synovial |
| another name for tumor | neoplasm |
| benign tumor | confined to a local area and does not spread |
| malignant tumor | tumor spread to neighboring tissues or to distant parts of the body |
| lipoma | a connective tissue tumor originating in fatty(adipose)tissue (benign) |
| 2 main categories of malignant tumors | carcinoma and sarcoma |
| symptoms of cancer | unusual bleeding,persistant indigestion, chronic hoarseness or cough,changes in color or size of moles, |
| biopsy | removal of living tissue for the purpose of microscopic examination |
| radiography | use of x-rays to obtain images of internal structures |
| ultra sound | use of high reflected frequency sound waves to differentiate various kinds of tissue |
| computed tomography | use of e-rays to produce a cross sectional picture of body parts |
| surgery to remove cancer | removes tumor surgically |
| radiation to remove cancer | x-ray or placement of small amounts of radioactive material with in the involved cell |
| chemotherapy to remove cancer | treatment of cancer with antioneoplastic agents |
| immunotherapy to remove cancer | use of substance that stimulat the immune system as a whole or vaccines |
| atrophy | muscles and other tissues waste from loss of cells with age |
| term mean in layers | stratified |
| any thin sheet of tissue that seperates two or more structures | membrane |
| visceral muscle also known as | smoothe muscle |
| Nerve impulses are carried away from the cell body by the | axon |
| the sheet of tissue that underlies the skin | superficial fascia |
| a tough membrane composed entirely of connective tissue that serves as a anchor and supports the organ or covers a muscle | deep fascia |
| pleurae are examples of this type of membrane | serous |
| the portion of serious membrane attached to an organ | visceral layer |
| connective tissue membrane that lines joint cavities | synovial |
| a tissue found in serious membranes | mesothelium |
| the portion of the serious membrane attached to the body wall | parietal layer |
| tough membranous tissue that encloses an organ | capsule |
| the cartilage found between bones of the spine | fibrocartilage |
| a fiber found in most connective tissues | collagen |
| a strong gristly cartilage that makes up the trachea | hyaline cartilage |
| type of connective tissue | areolar |
