Tissues
Chapter 5
| Question | Answer |
|---|---|
| What is the study of tissues? | Histology |
| What are the four tissue types? | Epithelial, Connective, Muscle, and Nervous |
| What is epithelial tissue composed of? | tightly packed cells with minimal extracellular matrix |
| What is the function of epithelial tissue? | Covers body and organ surfaces, lines body cavities, organ cavities, and forms some glands |
| What are the sub types of epithelial tissue? | Simple and Stratified |
| What are the sub types of simple epithelial tissue? | Simple squamous, simple cuboidal, simple columnar, pseudostratifed columnar |
| What are the sub types of stratifed epithelial tissue? | Stratified squamous, stratified cuboidal, stratified columnar, transitional |
| What is connective tissue composed of? | Cells, protein fibers, and ground substances |
| What is the function of connective tissue? | Binds, supports, and protects other tissues and organs |
| What are the subtypes of connective tissue? | Connective tissue proper, supporting connective tissue, and fluid connective tissue |
| What are the sub types of connective tissue proper? | Loose( areolar, adipose, reticular) Dense ( regular, irregular, elastic) |
| What are the sub types of supporting connective tissue? | Cartilage(hyaline, elastic, fibro) Bone |
| What are the subtypes of fluid connective tissue? | Blood and Lymph |
| What is muscle tissue composed of? | Cells that may be spindle shaped, branching, or cylindrical |
| What is the function of muscle tissue? | Moves the skeleton and organ walls |
| What are the subtypes of muscle tissue? | Skeletal, cardiac, smooth |
| What is nervous tissue composed of? | Contains neurons and glial cells |
| What is the function of nervous tissue? | Transmits nerve impluses and processes info |
| Are there any subtypes of nervous tissue? | No |
| What is simple epithelium? | One cell layer thick all cells are in direct contact with basement membrane |
| What is stratified epithelium? | Two or more layers of epithelial cells - Only deepest layer are in direct contact with basement membrane |
| What is pseudostratified epithelium? | Appears layered - classified as simple because all of cells are attached to basement membrane |
| What are squamous cells? | flat, wide, somewhat irregular shape |
| What are cuboidal cells? | As tall as they are wide |
| What are columnar cells? | slender and taller than they are wide |
| What are transitional cells? | Cells that can readily change shape |
| What is simple squamous epithelium? | single layer of flattened cells |
| What is simple cubodial epithelium? | single layer of cells about as tall as they are wide, spherical and centrally located nucleus |
| What is nonciliated simple columnar epithelium? | single layer of cells taller than they are wide, ovalshaped nucleus |
| What is ciliated simple columnar epithelium? | single layer of ciliated cells taller than they are wide, ovalshaped nucleus oriented lengthwise in basal region of cell |
| What is ciliated pseudostratifed columnar epithelium? | single layer of cells with varying heights, all cells connected to basement membrane - has goblet cells and cilia |
| What is nonciliated pseudostratifed columnar epithelium? | Single layer of cells with varying heights, all cells connected to basement membrane- no goblet or cilia |
| What is keratinized stratifed sqaumous epithelium? | multiple cell layers, basal cells are cuboidal - apical cells are dead and filled with protein kertain |
| What is nonkeratinized stratifed sqaumous epithelium? | multiple cells layers, basal cells are cuboidal - apical cells are alive and kept moist |
| What is stratifed cuboidal epithelium? | two or more layers of cells - about as tall as they are wide |
| What is stratifed columnar epithelium? | two or mote layers of cells- taller than they are wide |
| What is transitional epithelium? | Appearance varies depending on whether tissue is stretched or relaxed |
| What are the three basic components of a connective tissue? | cells, protein fibers, ground substance |
| What are the two classes of cells in connective tissue proper? | Resident cells and wandering cells |
| What are resident cells? | stationary cells that are permanently housed within connective tissues |
| What are wandering cells? | continuously move throughout connective tissue |
| What are examples of resident cells? | fibroblasts, adipocytes, mesenchymal cells, fixed macrophanges |
| What are examples of wandering cells? | Mast cells, plasma cells, free macrophanges, other leukocytes |
| Name the 3 protein fibers | Collagen, reticular, elastic |
| What are collagen fibers? | unbranced cable like fibers that are strong flexiable - In tendons and ligaments - white fibers |
| What are reticular fibers? | similar to collagen but thinner - in lymph nodes, spleen, liver |
| What are elastic fibers? | contain protein elastin - yellow fibers - in skin, arteries, lungs |
