TISSUE A group of cells that perform a similar function within an organism. Epithelium Connective Muscle Nervous CREDITS Epithelium Connective Muscle Nervous
Epithelium Composed of a layer of cells. Lines both the exterior and the interior Shape Squamous Cuboidal Columnar Transitional Stratification Simple: Single layer Stratified: Multiple layers Pseudostratified All cell shape epithelial (Squamous, Cuboidal, etc.) have both simple and stratified tissue. Only one contains pseudostratified. Simple Cuboidal Squamous Columnar Cuboidal Transitional Simple Cuboidal
Squamous Consists of flat cells Simple: cells are irregularly shaped and very flat Function: Diffusion Reduce friction Stratified: Several layers Function: Protection Squamous Columnar Cuboidal Transitional
Cuboidal Cube-shaped Simple: Surface of ovaries Function: Secretion Absorption Stratified: Sweat Glands Male Uretha Function: Protection Squamous Columnar Cuboidal Transitional
Columnar Column shaped Simple: Relatively thick and protective Lines the uterus Digestive tract Function: Absorption Noncilliated: No cilia Gastrointestinal tract Gallbladder Secretion Ciliated: Move mucus Upper respiratory tract The uterus Stratified: The uterus Male uretha Function: Secretion Protection Pseudostratified: Single layer of cells Nuclei placement Stratified Ciliated: Lines the trachea Upper respiratory tract Noncilliated: Male uretha Squamous Squamous Cuboidal Cuboidal Columnar Columnar Transitional Transitional
Transitional Multiple layers of cells Contracts and expands Stretches Found in: Urinary tract Urinary bladder Allows changes in liquid in an organ Fluctuates as needed Protection Unstretched Cuboidal Stretched Squamous Squamous Columnar Cuboidal Transitional
Connective Structure and support Proper Loose Dense Fibers Collagen Long structural protein Supports most tissues Gives cells structure Elastic Stretches and snaps back Reticular Supporting mesh Specialized Bone Cartilage Blood dense regular Connective Tissue Proper Bone Cartilage Blood
Proper Loose Holds organs in place Epithelia Attaches to layer underneath Made of fibers Collagen Contains fibroblasts Irregular cells Secretes fibrous proteins Dense Forms: Ligaments Tendons Collagen fibers Extremely strong Regular Strong tissue connection Irregular Not parallel like regular Connective Tissue Proper Bone Cartilage Blood
Blood Functions: Transport Oxygen Nutrients Hormones Made of Red blood cells White blood cells Platelets Connective Tissue Proper Bone Cartilage Blood
Bone Almost entire skeleton Functions Protection Structure Support Movement Skeletal muscles, tendons, ligaments Connective Tissue Proper Bone Cartilage Blood
Cartilage Dense connective tissue Composed of either/or Collagen fibers Elastin fibers Function: Supply smooth surface for bone movement Found at Joints Ear Nose Intervertebral discs Three main types: Elastic Hyaline Fibrocartilage Connective Tissue Proper Bone Cartilage Blood
Elastic Function: Permanently keep tubes open Withstands constant bending Found at Outside ear Larynx Similar to hyaline cartilage Contains elastic bundles within matrix Connective Tissue Proper Bone Cartilage Blood
Hyaline Avascular No nerves Found at The nose Ribs Fibers askew in matrix Connective Tissue Proper Bone Cartilage Blood
Fibrocartilage Made of Bundled connective tissue Cartilage cells in between Cells resemble Dense irregular s Tendon s During labor, aids in delivery Connective Tissue Proper Bone Cartilage Blood
Muscle 3 Main Groups: Skeletal Cardiac Smooth Involuntary: Movement not controlled Includes: Cardiac Smooth Voluntary: Movement controlled Includes: Skeletal Smooth Cardiac Skeletal
Smooth Involuntary Non-striated Hollow Organs Found in Respiratory tract Uterus Bladder Spindle shaped fibers Contract and relax Single nuclei Function: Stretch and elasticity Support Smooth Cardiac Skeletal
Skeletal Voluntary Controlled movement Involuntary: Reflexes Striated Attached to skeleton Function: Apply force to joints and bones Contract Movement Smooth Cardiac Skeletal
Cardiac Involuntary Striated Cross-striations Found in Heart (only) Function: Contraction Pump blood Smooth Cardiac Skeletal
Nervous Function: Communication React to stimuli Neurons Easily stimulated Transmit impulses Nerve Nerve cell fibers Neurons Makes up the nervous system Brain Spinal Cord
