Question | Answer |
---|---|
hist/o | web, tissue |
histology | study of composition and function of tissues |
psued/o | false |
pseudostratified epithelium | tissue with cells that appear to be in layers, but are not |
strat/o | layer |
Structures that connect cell membranes. | intercellular juctions |
Membranes of adjacent cells converge and fuse in what type of intercellular junction? | tight juction |
A type of intercellular junction that rivets or spot welds cells enabling them to form a reinforced structural unit. | desmosome |
A type of intercellular junction that connects cells by tubular channels. | gap junctions |
Four major tissue types: | |
Groups or layers of cells with similar origin and common function. | Tissues |
Three types of muscle tissue. | Skeletal, Cardiac, Smooth |
Connective tissue proper | Loose connective tissue and dense connective tissue. |
Specialized connective tissue. | Cartilate, Bone, Blood |
Tissue type that lacks blood vessels; readily divides; and cells are tightly packed. | Epithelial tissue |
Most abundant tissue type; cells are far apart. | Connective tissue |
Tissue type that is able to contract in response to specific stimuli. | Muscle tissue |
Tissue type with cells that communication with each other and other body parts. | Nervous tissue |
What are the functions of cartilage? | Protects underlying tissue and provides support and framework for the body. |
What best describes simple cuboidal epithelium? | A single layer of cube-shaped cells. |
What is the basic function of epithelial tissue? | Protective covering, secretion, absorption |
What is the basic function of connective tissue? | Support soft tissue; bind structures together |
What is the basic function of muscle tissue? | Produce body movements |
What is the basic function of nervous tissue? | Coordinate and control body activities |
What type of connective tissue that stores energy in the form of fat, cushions against trauma, and insulates against temperature changes? | Adipose tissue |
Where do most blood cells form? | In the hemopoietic tissue in the red marrow of certain bones. |
What type of fibers are produced by fibroblasts? | Collagen fibers, elastic fibers and reticular fibers. |
What type of fibers are thick threads, produced by fibroblasts, and are the major structural protein of the body. | Collagen fibers |
What are the three types of cartilage, distinguished by their types and extracellular matrix? | 1. Hyaline cartilage, most common, has very fine collagen fibers 2. Elastic cartilage, more flexible than hyaline, its extracellular matrix has dense network of elastic fibers. 3. Fibrocartilage, a tough tissue, many collagen fibers. Shock absorber. |
The most common type of cartilage. | Hyaline cartilage. |
Type of tissue that protects organs in body cavities, provides attachments for muscles, forms blood cells, and stores inorganic chemicals such as calcium and phosphorus. | Bone tissue |
Blood mostly composed of | Plasma and formed elements |
Some functions of blood. | Defense agains pathogens, blood clotting and transport of gases |
What type of cartilage is the most flexible due to its dense network of thin stretch fibers? | Elastic cartilage |
What is the extracellular fluid matrix component of blood | Plasma |
