Term
epithelial tissues may be divided into 2 functional types: 1.) _?_ 2.) _?_ |
|
Definition
covering and lining glandular epithelium |
|
|
Term
Although cells are highly organized entities, they function as isolated units in the body. (T/F) |
|
Definition
FALSE Although cells are highly organized entities, they do not function as isolated units in the body. |
|
|
Term
covering and lining epithelium forms the superficial layer of the _?_ and some _?__?_. Glandular epithelium makes up the _?__?_. Such as the _?__?_. |
|
Definition
skin internal organs secretory glands thyroid gland |
|
|
Term
| _?__?_ tend to be arranged in one or more layers and the basal layer always rests upon a basement membrane. |
|
Definition
|
|
Term
| Epithelium is classified based upon the _?_ of cell layers making up the tissue and according to the _?_ of the cells. |
|
Definition
|
|
Term
|
Definition
| single layer of cells found in areas where activities such as diffusion, osmosis, filtration, secretion, or absorption occur. |
|
|
Term
|
Definition
2 or more layers of cells found in areas subject to wear and tear where protection of underlying structures is required. Rare in body. EX: stratified columnar and stratified cuboidal. |
|
|
Term
| pseudostratified epithelium |
|
Definition
| one layer of a mixture of cell shapes giving a multilayered appearance. Upon close examination, one can see that each cell's basal end rests on the basement membrane, therefore it's not truly stratified (pseudo=fasle) |
|
|
Term
|
Definition
| squama=flat. They're flat and resemble a tiled floor. |
|
|
Term
|
Definition
| are thicker with cube or hexagonal shapes. Width is equal to approx. height. These cells are sometimes ciliated. Can be found in the proximal convoluted tubules of the kidneys where they function in absorption. |
|
|
Term
|
Definition
| Tall and cylindrical and may possess on their apical surfaces cell extensions such as microvilli (small intestine) or cilia (fallopian tubes). |
|
|
Term
|
Definition
| change shapes from flat to columnar, often due to distention or expansion, or movement of body parts. Found in the urinary bladder where the organ is subject to great distension as it fills with urine. |
|
|
Term
| all _?_ cells lie on a basement membrane |
|
Definition
|
|
Term
| Where are simple squamous epithelium cells found? |
|
Definition
| in the walls of the capillaries |
|
|
Term
| Where are simple cuboidal epithelium cells found? |
|
Definition
|
|
Term
| Where are pseudostratified columnar epithelium (ciliated) cells found? |
|
Definition
| tissue that lines the trachea. touch basement membrane. |
|
|
Term
| how many layers do stratified squamous epithelium cells have? |
|
Definition
|
|
Term
| Where are transitional epithelium cells found? |
|
Definition
| urinary bladder and ureters. no def. shape. |
|
|
Term
| Describe the anatomical structure of microvilli. What is its function? |
|
Definition
| small intestine. increase absorbtive area. |
|
|
Term
| How do cilia differ structurally and functionally from microvilli? |
|
Definition
Cilia- movement. move debris up so you can spit/cough it out, keep clean. |
|
|
Term
| What is a goblet cell and name 2 places in the body where this cell is found. |
|
Definition
| Produce mucous to coat linings. protection from acids, seeds, rough foods you eat. |
|
|
Term
| What is the most abundant and widespread tissue in the body that lends support, binds together, strenghthens other body tissues, and protects internal organs? |
|
Definition
|
|
Term
| What is the name of the cell that secretes matrix? |
|
Definition
|
|
Term
| What is the consistency of the matrix? |
|
Definition
|
|
Term
| What are the 4 subtypes of connective tissues? |
|
Definition
connective tissue proper cartilage bone blood |
|
|
Term
What does connective tissue proper contain? |
|
Definition
fibroblasts fibrocytes (mast cells, macrophages, adipocytes, etc.) |
|
|
Term
| Areolar (loose) connective tissue |
|
Definition
| serves as "packing material"- protects. |
|
|
Term
| adipose connective tissue |
|
Definition
|
|
Term
| _?_ attach muscle to bone. |
|
Definition
|
|
Term
| reticular connective tissues |
|
Definition
| internal framework of liver, spleen, kidney |
|
|
Term
| dense regular connective tissue |
|
Definition
stacked parallel (very densely) strongest of protein fibers matrix squeezed between collagen fibers nuclei-elongated, flat |
|
|
Term
| elastic connective tissue |
|
Definition
elastic fibers- wavy lines fibroblast found in walls in great arteries (aorta) |
|
|
Term
| What consistency is cartilages matrix? |
|
Definition
| firm and gelatinous (semi-solid). |
|
|
Term
| Why is cartilage a connective tissue? |
|
Definition
| provides a framework for the support of the rest of the body. |
