Epithelial Tissue 2. Connective Tissue What are the four different types of tissues? 3. Muscle Tissue 4. Nervous Tissue 1. Cellular Shape Tissues are identified by, what two things? 2. Arrangement 1. Cuboidal What are the 3 different types of cellular 2. Columnar shapes? 3. Squamous 1. Simple What are the four different types of 2. Stratified arrangements? 3. Transitional 4. Pseudostratified Columnar Epithelium Single layer What is the definition of simple epithelium? - All cells attached to basement membrane ex.1 Simple Cuboidal What are three examples of simple? ex.2 Simple Columnar ex.3 Simple Squamous What are examples of Simple cuboidal? cells of kidney tubules: Loop of Henle (Descending / Ascending) Distal Convoluted Tubule Function: Secretion and Absorption ciliated types propel mucus or reproductive cells What are some examples of Simple Columnar? lining of the small intestine (microvilli) Jejunum Function: 1. Absorption 2. Secretion of Mucus enzymes /other substances 3. ciliated type propels mucus or reproductive cells by ciliary action What are some examples of Simple Squamous? Bowman's Capsule Kidney's Glomeruli air sac of lungs (so thin) Function: Diffusion and Filtration What is stratified? In two or more layers 1. Stratified Cuboidal Give examples of three stratified 2. Stratified Columnar epitheliums? 3. Stratified Squamous Give an example of Stratified Cuboidal? Occurs in ducts of sweat glands Give an example of Stratified Columnar? Duct with two layers + columnar = Salivary glands in ducts of glands, usually a larger duct, thinner cells nuclei towards the side of basement membrane Give an example of Stratified Squamous? locations: Epidermis of skin (scalp) Lining of esophagus Skin Scalp Function: Protects underlying tissues in areas subjected to abrasion Cells that can change shape many layers thick, but inner layers are not squamous, unless ureter is stretched What is Transitional epithelium? Function: stretches readily and permits distention of urinary organ by contained urine Give an example of Transitional epithelium? ureter (not going to be stretched in microscope) many layers thick, but inner layers are not squamous, (unless ureter is stretched) when released go back to original shape Where is Pseudostratified Columnar Epithelium found? really only one layer but looks like more! Found in the respiratory system Ciliated All touch basement membrane Simple Squamous Epithelium identify this slide function? Function: diffusion, filtration, and secretion in serous membranes Simple Cuboidal Epithelium identify this slide? Function: secretion and absorption function? ciliated types propel mucus or reproductive cells Simple Columnar Epithelium of small intestine Function: secretion and absorption ciliated types propel mucus or reproductive cells identify this slide? Function? identify this slide Function? - Stratified Squamous Epithelium (Scalp) Function: Protection Stratified Squamous Epithelium (250X) identify this slide Transitional Epithelium (found in Ureter) identify this slide Function? Function: stretches readily and permits distention of urinary organ by contained urine Pseudostratified Ciliated Columnar Epithelium (as seen on slide of Larynx) identify this slide 250X Function? Function: secretion, particularly of mucus - propulsion of mucus by ciliary action Pseudostratified Ciliated Columnar Epithelium identify this slide Areolar Connective Tissue Functions: identify this slide? - wraps and cushions organs Functions? - holds and conveys tissue fluid plays important role in inflammation defends the body against infection stores nutrients as fats Adipose Function: identify this slide provides reverse food fuel Functions? insulates against heat lost supports and protects organs Dense Regular Connective Tissue (Tendon) identify this slide? Functions: Functions? attaches muscle to bone or muscle attaches bone to bone Dense Irregular Connective Tissue in the Dermis (adipose present) Function: able to withstand tension exerted identify this slide? in many directions Functions? - provides structural strength Compact Bone Function: identify this slide? bone support and protects (by enclosing) function? provides levers for the muscle to act on stores calcium and other minerals and fat identify slide? Cancellous (Spongy) Bone Hyaline Cartilage identify slide? Functions: Functions? - supports and reinforces has resilient cushioning properties resists compressive stress Elastic Cartilage identify slide? Functions? Functions: maintains the shape of a structure, while allowing great flexibility Erythrocytes Function: RBC, small, O2 transporting identify this slide? Neutrophil Function: destroys bacteria identify this slide? function? Monocyte Function: largest leukocytes use blo
