(29 cards)
Lining, covering, and glandular tissue of the body
Epithelial Tissue
____ = laid on, covering
epithe
Epithelial functions
Protection, Absorption, Filtration, Secretion
Classification of Epithelia
Simple Epithelia, Stratified Epithelia, Glandular Epithelium
One layer of cell
Simple epithelium
More than one layer
Stratified epithelium
Cell that is flattened like fish scales
Squamous cells
Cube-shaped like dice cell
Cuboidal cells
Shaped like columns
Columnar cells
Single layer of thin squamous cells resting on a basement membrane
Simple squamous epithelium
One layer of cuboidal cells resting on a basement membrane
Simple cuboidal epithelium
Single layer of tall cells that fit closely together
Simple columnar epithelium
Some of its cell are shorter than others, and their nuclei appear at different heights above the basement membrane
Pseudostratified columnar epithelium
Most common stratified epithelium in the body, and usually consists of many cell layers
Stratified squamous epithelium
Two cell layers with (at least) the surface cells being cuboidal in shape
Stratified cuboidal epithelium
Columnar cells, but its basal cells vary in size and shape
Stratified columnar epithelium
Highly modified, stratified squamous epithelium that forms the lining of only a few organs
Transitional epithelium
Gland consists of one or more cells that make and secrete a particular product
Glandular epithelium
Two major types of glands develop from epithelial sheets
Endocrine, Exocrine
Retain their ducts, and their secretions exit through the ducts to the epithelial surface
Exocrine Gland
Lost their ducts; thus they are often called ductless glands. Their secretion diffuse directly into the blood vessels that weave through the glands.
Endocrine Gland
Major connective tissue
Bone, Cartilage, Dense Connective Tissue, Loose Connective tissue, Blood
Composed of osteocytes
Bone
Less hard and more flexible than bone. Its major cell type is chondrocytes
Cartilage
