Card preview (24)
Enumerate the 4 general types of animal tissues.
• epithelial • connective • muscle • nervous
Enumerate the 3 general functions of epithelial tissues.
• cover body surfaces • line body cavities and ducts • form glands
It refers to tissues that bind, support, and protect body parts.
connective tissues
It refers to tissues that produce movement via contractions.
muscle tissues
It refers to tissues that transmit nerve impulses from one body part to and from the spinal cord and brain.
nerve tissues
It refers to the material surrounding the cells.
extracellular matrix
TRUE or FALSE: The composition of the extracellular matrix varies among different tissue types.
True
Enumerate the 2 types of epithelial tissues according to function.
• membranous epithelia • glandular epithelia
It is described as epithelial tissues which consist of sheets of tightly packed epithelial cells that line the organs.
membranous epithelia
It is described as epithelial tissues which consist of clumps of epithelial cells that form glands.
glandular epithelia
TRUE or FALSE: Epithelial cells are polar, which means they have a distinct basal and apical side.
True
The surface of an epithelial tissue which is anchored to the thin, sheet-like extracellular matrix.
basal surface
It refers to the thin, sheet-like extracellular matrix.
basement membrane; basal lamina
It refers to the surface of an epithelial tissue facing towards the external environment or towards the lumen.
apical surface
It refers to the cavity at the center of a tubular structure.
lumen
Enumerate the 2 classifications of membranous epithelia according to the number of cell layers.
• simple - single layer • stratified - multiple layers
Enumerate the 3 classifications of the cells in the membranous epithelia and describe their shapes.
• squamous - flat cells • cuboidal - cube shaped cells • columnar - elongated cells
Identify which membranous epithelia is described below: single layer of flat cells
simple squamous epithelia
Identify which membranous epithelia is described below: single layer of cube-shaped cells
simple cuboidal epithelia
Identify which membranous epithelia is described below: lines small ducts and tubules
simple cuboidal epithelia
Identify which membranous epithelia is described below: single layer of elongated cells
simple columnar epithelia
Complete the sentence below: The stratified epithelia of frog skin consist of __________ epithelial cells found on the surface and layers of __________ epithelial cells beneath.
squamous; cuboidal or columnar
Which non-keratinized epithelia line moist internal cavities such as the oral mucosa and esophagus?
stratified squamous epithelia
Complete the sentence below. The functional units of the glandular epithelia may be __________ or __________.
unicellular; multicellular
