bio exam 2 quiz
| Question | Answer |
|---|---|
| This tissue covers body surfaces and lines hollow organs of the body such as the stomach and bladder. | epithelial tissue |
| Of the four basic tissue types, which one is able to generate electrical signals that can trigger muscles contractions or glandular secretions? | nervous tissue |
| Which type of cell junction would you expect to find anchoring the cells of the epidermis to each other. This type of junction gives the skin its ability to endure stretching and other mechanical stresses without tearing. | desmosomes |
| This type of junction contains tiny fluid-filled tunnels called connexons: allow movement of ions & small molecules between cells. Found between muscles cells of the heart and in organs with smooth muscle tissue such as the gastrointestinal tract. | gap junctions |
| If you wanted to design a tissue that restricted the movement of water and other molecules between adjacent cells, which type of junction would you use to connect the cells? | tight junctions |
| This tissue has an extensive extracellular matrix, usually has many blood vessels, and provides oxygen and nutrients to overlying tissues. | connective tissue |
| Which type of tissue is found in the tubules of kidneys, the covering of the ovaries, and also in glandular tissues such as the thyroid gland? Its function is absorption and secretion. | simple cuboidal epithelium |
| This type of epithelium has elastic properties. It is 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. What is this tissue? | transitional |
| Which type of exocrine gland are sebaceous (oil) glands? | holocrine |
| Which of the following is not an example of an exocrine gland? | pituitary gland |
| 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 __________? | extracellular matrix |
| Where are mesenchymal cells found? | near the basement membranes of epithelial 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 type of muscle tissue would have these characteristics: branched cells, usually has one nucleus, has striations (a striped appearance)? | cardiac |
| Which type of muscle tissue is under the voluntary control of our nervous system. We can consciously control the movement of this type of muscle tissue | skeletal |
| Which type of muscle tissue is found in the walls of hollow organs and is not under voluntary control | smooth |
| Of the basic tissue types, which types have excitable cells? | muscle and nervous tissues |
| Tight junctions allow ions, nutrients, and waste products to freely move between cells. | false |
| Blood has a fluid extracellular matrix with cellular elements in it. | true |
| The cells of the nervous system which are able to generate nerve impulses (action potentials) are called neuroglia. | false |
