Review questions 2
| Question | Answer |
|---|---|
| A group of cells that have a common origin and function together to perform a specialized group of activities is a | tissue |
| This tissue covers body surfaces and lines hollow organs of the body such as the bladder and stomach | Epithelial Tissue |
| This type of tissue can function as fat storage, pad out and bind an organ together, wrap skeletal muscles, or transport substances | Connective Tissue |
| Which type of cell junction would you expect to find anchoring the cells of the epidermis to each other. This types of junction gives the skin the ability to endure stretching and other mechanical stresses without tearing. | Desmosomes |
| This type of junction contains tiny fluid filled tunnels called connexons which allow the movement of ions small & molecules between cells. Its found between muscle cells of the heart and in organs with smooth muscle tissue such as gastrointestinal tract | Gap junctions |
| If you wanted to design a tissue that restricted the movement of water and other molecules which junction would it be | Tight junction |
| In this type of cell junction the transmembrane proteins are integrins which anchor the cell to basement membranes | Hemidesmosomes |
| This tissue has extensive extracellular matrix, usually has many blood vessels, and provides oxygen and nutrients to overlying tissues | Connective tissue |
| Which tissue depending in its location and functions is called endothelium or mesothelia | Simple squamous epithelium |
| Which type of tissue is found in the tubules of kidneys, the covering of ovaries, and also in glandular tissues such as the thyroid gland? its function is absorption and secretion | Simple cubodial epithelium |
| This type of epithelium has elastic properties. its able to stretch and return to a less stretched condition. When stretched the cells at the top flatten out and when relaxed they become rounded | Transitional |
| Which type of exocrine gland are sebaceous (oil) glands | Holocrine |
| Which type of connective tissue provides the supporting framework for the liver, spleen, lymph, nodes, and red bone marrow | Reticular |
| All connective tissues consist of two basic elements: | Cells and extra cellular matrix |
| Where are mesenchymal cells found | In embryonic connective tissues |
| The function of ______ is to store triglycerides | Adipocytes |
| Where would you be able to find dense regular connective tissue in the body | In tendons and ligaments |
| This type of connective tissue has no direct blood supply in its extracellular matrix, which makes it slow to heal | Cartilage |
| Which of these serous membranes line the abdominal cavity & covers the abdominal organs | Peritoneum |
| Faster healing with fewer scars in the young can be explained by ? | Better blood supply to tissues, better in take of nutrients in a younger person, more metabolically active cells |
| These cells are found near blood vessels in connective tissue and release histamine to promote inflammation as a response to injury or injection | Mast cells |
| Which of the following restricts movement or entry of chemicals into the epithelium | Tight junctions |
| Which of the following cell junctions attaches epithelium to the basement membrane | Hemidesmosome |
| If a person has a herniated vertebral disc, which cartilage has been damaged? | Fibrocartilage |
| Why can cartilage rarely heal itself/continue to grow? | It lacks a direct blood suuply which is necessary for healing, anti-angiogensis factos secreted into the matrix, and chondroblasts are nto present in the EC matrix |
| Lack of vitamin C in the diet interferes with the ability of fibroblasts to produce collagen. What affects might this interference have on CT? | Tissue is weak and prone to damage |
| Connective tissues share three basic components | Specialized cells, EC fibers, and ground substance |
| Where is elastic cartilage located in the body | It forms part of the exterior nasal system and the external ear |
| Why are blood and bone classified as supportive connective tissue | Because they form the framework of the body |
| Mesenchyme connective tissue gives rise to which tissue type? | All connective tissues |
| This epidermal layer contains melanocytes, and merkel cells | Stratum basale |
| Theses layers contain areolar connective tissue | Papillary dermis and hypodermis |
| These sweat glands are found primary with hairy skin | Apocrine |
| Which phase of wound healing is characterized by the arrival of fibroblasts at the wound site? | Migration |
