Term | Definition |
Epithelial Tissue- Function | protective tissue |
Connective Tissue -Function | connects other tissue and forms the components of the intercellular material |
Muscle Tissue -Function | properties of changing shape |
Nervous Tissue -Function | respond to environmental changes, communication from the body to the brain and other parts of the body |
Epithelium tissue | covers surfaces and lines internal structures and cavities |
Characteristics of Epithelium | cells compact together
one or more layers
singe layers- transport materials
2 or more layers - protect against bacteria
(cilia-movement , microvilli- absorption |
Characteristics of Connective | cells, fibers, and proteins = intercellular material
support and flexibility and binds structures
(tendons/ligaments) |
Cellular Components
(Connective) | important for transport and storage of materials and protect against foreign materials |
Matrix
(Connective) | intercellular fluid may exit as a fluid, semi-fluid, gelatinous or solid substances
Connective- serve as a medium to transport and store soluble substances, protective lining between and around structures and a medium to fill spaces |
Nervous tissue | collects and transmits info by means of different types of nerve cells
some sensitive to external changes
others carry proper responses |
Muscle tissue | |
Simple Squamous
(Epithelial Tissue) | flat an thin found in the lining of the blood vessels, heart and lungs
funct. secretes serous fluid to reduce friction
between membranes |
Stratified Squamous
(Epithelial Tissue) | tall and cylindrical or flat, forms layer, found covering tissues or organs
funct. protects organs against injury |
Simple Cuboidal
(Epithelial Tissue) | cells almost square shaped, found in secretory glands, kidney tubules and covering ovaries
funct. secretes certain tissue fluids |
Simple Columnar
(Epithelial Tissue) | cells tall and packed together, found in digestive tract
funct. protect organs, secrete mucus secretions which lubricates epithelial surfaces |
Ciliated
(Epithelial Tissue) | modified columnar, contains hairlike projections, found in nucleus and reproductive organs
funct. cilia aid in movement of particles |
Loose Connective | few cells and many fibers in a semi- fluid matrix found directly beneath the epithelium of skin
funct. supports and surrounds organs
collagen- flexible
elastin- single interlacing fibers |
