Tissue Types Flashcards
The four basic tissue types are:
- Epithelial
- Connective
- Muscle
- Nervous
The tissue type specialized for linking tissues and organs together is:

muscle tissue
The tissue type specialized for forming barriers is:
epithelial tissue
The tissue type specialized for generating and transmitting impulses is:
nervous tissue
The tissue type that forms the immune system is
connective tissue
True or false? Epithelia is vascular (contains blood cells)
False. Epithelia is avascular
Epithelia rests on the _____ ______.
Basal lamina.
The apical surface of epithelia is _______, while the basal surface is ______.
Exposed/external, hidden/internal
The simple squamous epithelium that lines body cavities is called the __________.
mesothelium
The simple squamous epithelium that lines heart chambers and blood vessels is called the __________.
endothelium
The type of epithelium found in glands and their ducts is called
simple cubiodal
The type of cilliated epithelium that lines the digestive tract, fallopian tubes & excretory ducts are called
simple columnar
The type of epithelium found in areas with severe mechanical stress are called:
stratified squamous
Keratin is good for ____ cells because it is ____ ______, but that also makes it bad for other areas of the body.
skin cells, water-resistant
The type of epithelium that is relatively rare, found in larger exocrine glands, is called
stratified cuboidal
The type of epithelium that is relatively rare, found in larger excretory ducts, is called
stratified columnar
In a pseudostratified columnar epithelium, all cells touch the _____ _____, but ____?
the basal lamina, but they may not reach the luminal surface
The type of epithelium found only in the urinary system has ____-shaped outermost cells and is called
dome-shaped, transitional epithelium.
Glands are composed of ________ cells.
epithelial
Exocrine glands release secretions where?
Through ducts and onto the surface.
Endocrine glands release secretions where?
Into the bloodstream.
The mechanism of secretion wherein normal exocytosis happens is called
merocrine
The mechanism of secretion wherein the apical surface is pinched off, secreting all at once, is called
apocrine
The mechanism of secretion wherein the entire cell is released and must be produced anew is called
holocrine
The three parts of connective tissue matrix are:
- Collagen
- Reticular
- Elastic
What do the fibroblasts in connective tissue do?
They secrete ground substance and fibres.
What do the macrophages in connective tissue do?
They digest debris and function in immune system response.
Mesenchyme are also known as ____ ____.
Stem cells
