Chapter 4 Tissue
Tissue
| 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 |
