tissues
| Question | Answer |
|---|---|
| what are the four basic types of body tissues | epithelial, connective, muscular, and nervous |
| what characteristics is used to name tissue types | organization of cells |
| The type of intercellular junction that functions as a rivet or "spot weld" | desmosome |
| type of intercellular junction that forms tubular channels | gap junction |
| type of intercellular junction that consists of fused membranes | tight junction |
| tissue through which gases are exchanged between the blood and the air in the lungs | Simple Squamous Epithelium |
| Epithelial tissue functions in | secretion, absorption, and protection |
| A Basement membrane anchors | epithelial to connective tissue |
| type of epithelium that lines the urinary bladder and many of the urinary passageways | transitional |
| A carcinoma is a cancer originating from | epithelium |
| type of tissue lines the follicles of the thyroid glands | Simple cuboidal epithelium |
| The type of epithelium that secretes into ducts that open onto surfaces like skin or into body fluids | Grandular Epithelium |
| branches repeatedly before reaching the glandular cells or secretory part | compound gland |
| _______ tissue contains collagenous fibers, elastic fibers, and gel-like ground substance | Areolar |
| Tendons and ligaments are composed primarily of | dense regular connective tissue |
| Bone cells form concentric circles around longitudinal tubes called | central canals |
| What is a cellular fragment | blood platelets |
| produce connective tissue fibers | fiberblast |
| Adipose tissue is a form of | connective tissue |
| Extracellular matrix consists of | ground substance and protein fibers |
| Epithelial membranes are typically composed of | epithelium and underlying connective tissue |
| ____ membrane has tubes and cavities that open to the outside of the body | mucous |
| Cutaneous membrane refers to | skin |
| Involuntary muscles are | smooth and cardiac |
| Muscle cells with more than one nucleus | skeletal only |
| Muscle tissue that can be consciously controlled is | skeletal |
| Smooth muscle is found | in the wall of the stomach and intestine |
| type of muscle tissue in blood vessels is | smooth muscle |
| _____ fuction to support and bind nervous tissue and provide nutrients and growth factors to neurons by connecting them to blood vessels | neuroglia |
| Mutations usually disrupt collagen's function because | collagen has a very precise structure |
| Which of the following is not true about the extracellular matrix? | it is the same in all tissues |
| The antihistamine Benadryl has a sedative effect, but the antihistamine Zyrtec does not, because | Benadryl crosses the blood-brain barrier but Zyrtec does not. |
| Bone tissue contains abundant | collagen |
| The differences among merocrine, apocrine, and holocrine secretions are the | amount of cytoplasm secreted along with the glandular product. |
| Cartilage heals slowly because | chondrocytes do not have direct blood supplies |
| The blood brain barrier (BBB) consists of | tight junctions between endothelial cells that form the capillary walls. |
| elastic connective tissue forms | elastic fibers |
| what are the general characteristics of connective tissues? | common origin of connective tissue from mesenchyme, varied degrees of vasculacity and a large amount of extracellular matrix that varies with tissue type all characterize. |
| About 90% of all cancers originate from | epithelium |
| Embryonic stem cells growing in a lab dish are bathed in a "cocktail" of chemicals that cause them to specialize into branching networks of single-nucleated cells that pulsate in unison. This tissue is most likely | cardiac muscle |
| An engineered tissue might include | A.stem cells. B. progenitor cells. C.a scaffold built of synthetic materials D.extracellular matrix components |
| The basis of using proteomics to describe tissues is that | Different cell types produce different sets of mRNAs |
| Which of the following is not a characteristic of nervous tissue? | Its intercellular space is filled with collagen. |
| Cardiac muscle is found in the wall of the | A.stomach.B.intestine.C.urinary bladder.D.eyeball. *E.none of the above |
| There are __ types of muscle cells. | 3 |
| A serous membrane consists of a | layer of simple squamous epithelium and a thin layer of loose connective tissue. |
| A ______ gland does not branch before reaching the glandular cells or secretory part. | simple |
| The tissue that forms the inner lining of the respiratory passages is | mucus-secreting, ciliated, and pseudostratified. |
| intercellular junctions connect | cell membranes |
