What are the functions of Epithelial Tissue?
|
Covers the surface of the body. Lines hollow organs, cavaties and ducts. Forms the glands of the body
|
|
Does epithelial tissue contain nerves and blood vessels?
|
It contains nerves but no blood vessels (avascular)
|
|
What are the names of the 5 cell junctions which hold the epithelial cells together?
|
Tight junctions, gap junctions, desmosomes, hemidesmosomes, adherens junctions
|
|
What is the function of The Basement Membrane?
|
Supports the epithelium. Provides a surface along which epithelial cells migrate during growth and wound healing. Acts as a physical barrier.
|
|
Name and the describe the two parts that make up the basement membrane.
|
Basal lamina which is secreted by overlying epithelia and contains collagen and laminin. Reticular lamina which is produced by underlying connective tissues and contains fibrous proteins
|
|
Define Tissue
|
A tissue is a group of cells that usually have a common origin in an embryo and function together to carry out specialised functions
|
|
Define Cell junctions
|
A contact point between plasma membranes of adjacent tissue cells
|
|
Name the two types of Epithelial Tissue
|
Covering & Lining Epithelia. Glandular Epithelia
|
|
Which type of Epithelia Tissue forms the outer covering of the skin and some internal organs, and forms the lining of the blood vessels, ducts, body cavaties and the interior of the respiratory digestive, urinary and reproductive systems?
|
Covering and Lining Epithelia
|
|
Which type of Epithelial tissue makes up the secreting portion of glands eg. thyroid gland, adrenal gland and sweat gland?
|
Glandular Epithelia
|
|
What is the difference between stratified and pseudostratified tissue?
|
Stratified consists of two or more layers, whereas pseudostratified just appears to have multiple layers when actually all cells rest on the basement membrane
|
|
Which is taller than it is wide, Squamous, cubodial or columnar cells?
|
Columnar
|
|
Which is flat, cubodial or squamous cells?
|
Squamous
|
 Which cell type most commonly lines the cardiovascular system, where it is known as endothelium? Present at sites of filtration, diffusion and secretion but not wear and tear |
Simple Squamous
|
 Which cell type is a single layer of cube-shaped cells, found in areas of secretion and absorption such as the surface of ovaries, kidney tubules and ducts and the secreting portions of some glands? |
Simple Cubodial
|
