Tissue Review
Term | Definition |
---|---|
Cells | Building blocks of all living things |
Tissue | Group of cells that are similar in structure and function |
Epithelial Tissue | Tissue that protects, absorbs, filters and secretes |
Avascular | No blood supply |
Simple | One layer of cells |
Stratified | More than one layer of cells |
Squamous | Flattened shape to cell |
Cuboidal | cube-shaped cells |
Columnar | column-shaped cells |
Simple squamous | Single layer of flat cells that line the lungs and capillaries. Usually used for exchanged between body and external environment |
Simple Cuboidal | Cells that form the walls of kidney tubules Function: protection, absorption and secretion |
Simple Columnar | Lines the digestive tract Contain goblet cells that produce mucus |
Pseudostratified Epithelium | Line the respiratory tract Contain cilia and used for absorption and secretion |
Stratified Squamous | Form Skin and esophagus Functions: protection |
Transitional Epithelium | Forms the urinary bladder and has the ability to stretch |
Endocrine glands | Ductless glands that secrete hormones and other substances into the body |
Exocrine glands | Empty substance through ducts in epithelial tissue Example: Sweat glands |
Bone | Used to protect and support the body Forms a very hard extra cellular matrix |
Hyaline Cartilage | Composed of collagen fibers Used for cushioning between joints, and make up fetal skeleton |
Fibrocartilage | High compressible cartilage Forms the vertebral disks that space bones in vertebral column |
Tendon | Dense connective tissue that attach muscle to bone |
Ligament | Dense connective tissue that attach bone to bone |
Areolar Tissue | Contains all fiber types Located directly underneath stratified squamous epithelium |
Adipose Tissue | Used for insulation and fuel storage Contains large lipid deposits |
Reticular Tissue | Connective tissue that makes up the supporting network of spleen, lymph nodes and bone marrow |
Blood | Liquid connective tissue used for transport |
Skeletal muscle | Striated, voluntary muscle Example: Bicep |
Smooth Muscle | Non-striated, involuntary muscle that makes up digestive tract |
Cardiac muscle | Striated, involuntary muscle that forms the heart |
Neural tissue | functions to send impulses to other areas of the body |
Regeneration | Replacement of destroyed tissue by the same kind of cells |
Fibrosis | repair by dense fibrous connective tissue (scar tissue) |
