- 14 types of TissuesEpithelial
Connective
Muscle
Nervous - 2Epithelial TissueIt is a covering and a lining
- 3Nervous TissueBrain and Spinal Cord
- 4Muscle Tissue3 types - smooth, cardiac, and skeletal
- 5Connective TissueMost abundant tissue by weight. It is everywhere. It is vascular
Eg: blood. - 6Number of cell layers in the 4 types of tissue layers1) Simple -1 row
2) Stratified - more than 1 row
3) Pseudostratified - False rows. Not actually stacked. Usu. columnar cells
4) Transitional - Cells changing shape. - 7Cell ShapesSquamous
Cuboidal
Columnar - 8SquamousTend to be flat
- 9CuboidalLook like cubes. Very round nucleus with cytoplasm on all 4 sides. Located where there is absorption or secretion
- 10ColumnarNucleus usually in bottom 1/3 with cytoplasm on top. Simple columnar in digestive system
- 11Transitional Epithelial CellsIn bladder and urethra and ureters
- 12Simple Squamous EpitheliumAbove basement membrane (more superficial). Use nucleus placement for identification*** (Nucleus in 1 row)
- 13Simple Columnar EpitheliumGoblet cells. Most likely trachea or intestinal/digestive tract
- 14Stratified squamous epitheliumMultiple nuclei rows. Esophagus. Non-karatinized (no need for waterproofing)
- 15Stratified cuboidal epitheliumSalivary gland - equal cytoplasm, nuclei in centres of cells
- 16Transitional EpitheliumIn organs that change shape. eg. bladder
- 17Epithelial Tissue Surface Specialization1) Smooth Surfaces
2) Microvilli
3) Cilia
4) Keratin - 18Epithelial Tissue Surface Specialization - Smooth SurfacesEg. linings of blood vessels
- 19Epithelial Tissue Specialization - MicrovilliMultiple finger - like projections
Increases surface area of cell/plasma membrane
Absorption, secretion (eg. intestinal or urinary tract) - 20Epithelial Tissue Surface Specialization - CiliaMultiple hair-like projections
Transport material along cell/tissue surface (eg. trachea and mucus) - 21Epithelial Tissue Surface Specialization - KeratinProtective waterproof substance in mature epithelial cells
- 22Pseudostratified columnar with ciliaEg lungs or trachea
- 23Keratinized stratified squamousHigh area of friction. Could be skin or esophagus, but we have a cornified (keratin) layer, which won't be present in esophagus
- 24Connective Tissue Classification - 2 typesProper and Specialized
- 25Connective Tissue Classification - Proper Typea) Loose
-Areolar
-Adipose
-Reticular
b) Dense
-Regular
-Irregular
-Elastic - 26Connective Tissue Classification - Specialized Typea) Bone
-Spongy
-Compact
b) Blood
c) Cartilage
-Hyaline
-Elastic
-Fibrocartilage - 27Loose Connective Tissue - AdiposeFat. Looks like big fat ping pong balls
- 28Loose connective tissue - AreolarMost abundant. Very loose. There are so many adipose cells in the body. Overweight people have larger adipose cells, and when they lose weight the cells shrink, but never disappear.
- 29Loose reticular connective tissueFramework of organs
- 30Dense regular connective tissueAchilles tendon (for an example)
- 31Dense Irregular Connective TissueSome branching, not perfectly straight and linear. Provides more give. Eg. heart pumping
- 32Elastic Connective TissueNeed them to open and close quickly. Eg. in arteries
- 33Spongy BoneArea where blood is produced
- 34Cartilage: HyalineBluish tinge on view (microscope) Eg. trachea. Has some give
- 35Cartilage: ElasticAreas where we need recoil. Eg. outer ear
- 36Cartilage: FibrocartilageIn areas of compression. Eg. b/w vertebrae
- 37Muscle TissueSmooth - no control over (eg. stomach. Involuntary)
Cardiac - Heart muscle
Skeletal - Voluntary. Biceps and triceps - 38Cardiac MuscleIntercalated discs are the only way to tell the difference between cardiac and other types. 1 nucleus/cell. On slides note dark pink lines - intercalated discs
- 39Skeletal MuscleNuclei in periphery of cell. Can be binuceated. Lots of striations. Super long cells.
- 40Smooth MuscleNo striations, short and branching cells. Lining hollow organs (eg. bladder)
- 41Nervous TissueNo connective tissue within the brain and spinal cord. Space occupied by glial cells. Neurons have larger cell body and nuclei +/- axons
