|
Epithelial tissue |
covers body surfaces, internal and external |
|
|
Connective tissue |
protection and support of body structures |
|
|
Muscle tissue |
provides the force necessary for movement |
|
|
Nervous tissue |
coordination of body activities |
|
|
Apical (free) surface |
the outer edge (e.g. surface of the skin) |
|
|
Lumen |
the space that lies next to the apical surface of certain epithelial tissue |
|
|
Basal surface |
attaches to the connective tissue |
|
|
Basement membrane |
a thin structure which usually consist of two layers that are located between the connective tissue and epithelial cells |
|
|
Avascular |
lacking a blood supply, epithelial tissue lacks blood vessels |
|
|
Squamous |
flattened, scale-like |
|
|
Cuboidal |
cells as tall as they are wide |
|
|
Columnar |
cells that are taller than their width, are cylindrical or rectangular |
|
|
Transitional |
these cells change shape as they are stretched |
|
|
Simple |
a single layer of cells |
|
|
Stratified |
tissue is two or more layers of cells in thickness |
|
|
Pseudostratified |
a single layer of cells that appear to be stratified, i.e. not all of the cells extend to the apical surface (the nuclei are located at different levels) |
|
|
Cilia |
hair-like structures that move substance along the surface of cells |
|
|
Microvilli |
finger-like cytoplasmic projections that increase surface area |
|
|
Goblet cells |
modified columnar cells that secrete mucous |
|
|
Fibroblasts |
cells that secrete fibers and ground substance |
|
|
Macrophages |
produced from monocytes |
|
|
Plasma cells |
produce antibodies |
|
|
Mast cells |
release histamine to cause vasofilation |
|
|
Adipocytes |
"fat cels", store triglycerides |
|
|
Chondrocytes |
"cartilage cells", produce and maintain cartilage |
|
|
Osteocytes |
"bone cells", maintain osseous tissue |
|
|
Matrix |
material that fills the area between cells |
|
|
Ground substance |
non-cellular material secreted between connective tissue cells examples of key components: - calcium hydroxyapatite (bone) - chondroitin sulfate (cartilage) |
|
|
Fibers |
helps strengthen and support connective tissue |
|
|
Collagen fibers |
long chains of the protein collagen, are flexible but resist stretching (have a high tensile strength) |
|
|
Elastic fibers |
composed of the protein elastin, thinner than collagen fibers, can be stretched up to 1 1/2 times their length without being damaged and are able to return to their original length |
|
|
Reticular fibers |
provide a supporting framework in many tissues, ex. liver, spleen, lymph nodes |
