Anatomy Ch. 5 Tissues Flashcards
Bone is considered what tissue?
Connective tissue
Name the four main types of tissues
Epithelial, Connective, Muscular, Nervous
Characteristics of Epithelial Tissues
Cover organs and body surface, Have a free (apical) surface exposed to an open space, anchored to Basement membrane, Lacks blood vessels
Name three cell shapes
Squamous (thin & flattened), Cuboidal (glands & cubes), Columnar (tall & elongated)
Number of cell layers
Simple (1 layer), Stratified (2 or more layers)
How do you determine cell layers?
count from free space to Basement Membrane
What does the Basement Membrane do?
Anchors Epithelial tissue to connective tissue
Cells can be…?
ciliated and nonciliated
Extensions from free surfaces of certain cells
Cilia
Scattered, secretes mucus for protection and Lube
Goblet Cells
Some cells contain this to increase surface area for absorption
Microvilli
Pseudostratified
False or fake layer
In the Skin, outer layers of cells go through
Keratinization
Stratified Cuboidal
Consists of 2-3 layers, forms lining of Lumen, lines ducts of mammary glands
Cell tissue designed to stretch (distend) and then return to normal size. (Bladder) functions as expandable lining
Transitional Epithelial
What cells are most likely to diffuse
Squamous cell
Produce & secrete substances into ducts or into body fluids
glands, exocrine glands
Endocrine glands
secrete into body fluids or blood
Fat cells
Adipocytes
Bones cells
Osteocytes
Nerve cells
Neurons
See cilia think…
Pseudostratified columnar epithelium
Lumen
Tube like opening
Stratified columnar epithelium is a …
