Four types of tissues. Epithelial Connective Muscle Nervous
Make up organs Connective Nervous Epithelial Muscle Credits

Most common Most widely
distributed 5 main functions

Stands up to tension and compression
Its both tough and flexible
80% water Rarely found in
adults
Home Connective Tissues Elastic CartilageHyaline Fibrocartilage
Similar to Hyaline cartilage
More elastic Cartilage
Maintains shape but still flexible
Home Connective Tissues Cartilage Hyaline Fibrocartilage
Most common Cartilage
Contains imperceptible collagen fibers
Forms the costal cartilage
Found at the end of bones and compression points Home Connective Tissues Cartilage
Elastic Cartilage Fibrocartilage
Intervertebral disks Compressible and
Resists tension Able to withstand
heavy pressure
Home Connective Tissues Cartilage Elastic Cartilage Hyaline
Two subclasses Loose Dense
Home Connective Tissues Loose Dense
Parallel Collagen Fibers
Subcatagorizied Regular and
Irregular
Home Connective Tissues ProperRegular Irregular
Parallel collagen fibers
Fibroblasts commonly found
Can withstand tension
Found in digestive tract
Home Connective Tissues Proper Dense Regular
Parallel collagen fibers
Fibroblasts commonly found
Found in Tendons
Home Connective Tissues Proper Dense Irregular
Consists of ground substances, fibers, and masenchymal cells
Can become any other tissue type
Found in embryo
Home Connective Tissues
Broken down into three subclasses: Reticular Areolar Adipose
Home Connective Tissues Proper Reticular AreolarAdipose
Very Rare Cells lie in a fiber
network Supports other
systems
Home Connective Tissues Proper Loose Areolar Adipose
Gel-like matrix Wraps and
cushions organs Found throughout
body
Home Connective Tissues Proper Loose Reticular Adipose
Gel-like matrix Reserves food Found under skin Provides nutrients
to organs
Home Connective Tissues Proper Loose Reticular Areolar
Supports Protects and aids
muscular action Hollow with hard
collagen fibers Stores nutrients
Home Connective Tissues
Fluid matrix Found in blood
vessels Used to transport
nutrients
Home Connective Tissues
Compose entirely of cells
Either simple or Stratified
Supported by fibers
Home Simple Stratified
One Layer Cubodial Squamous Columnar
IrregularPseudostratified
Columnar
Home Epithelial Cubodial Squamous Pseudostratified Columnar Columnar
Single layer Often with cilia Found in tubes Absorption and
secretion
Home Epithelial Simple Squamous Pseudostratified Columnar Squamous
Single layer Pancake Shaped Disk shaped nuclei Slick Surface Diffusion and
Filtration
Home Epithelial Simple Cubodial Pseudostratified Columnar Columnar
Single layer Often with cilia Goblet cells
included Oval nuclei
Home Epithelial Squamous Cuboidal Pseudostratified Columnar
Single layer with different heights
Secretion and propulsion of mucus
Ciliated and non-ciliated
Home Simple Epithelial Cuboidal Squamous Columnar
More than one cell layer Squamous Cubodial Columnar
One irregularTransitional
Home Epithelial Squamous CubodialColumnar Transitional
Extremely rare Found in glands 1-2 layers Protection
Home Epithelial Stratified Squamous Columnar Transitional
Found in places of Abrasion
Thick membrane Many layers Forms outer layer
of epidermis Surface cells are
dead
Home Epithelial Stratified Cubodial Columnar Transitional
Limited distribution Transitions
between epithelia Protection and
Secretion
Home Epithelial Stratified Squamous Cubodial Transitional
Several layers Cubodial and dome
shaped cells Stretches
Home Epithelial Stratified Cubodial Columnar Squamous
Contract and
release Three main types
Skeletal Cardiac Smooth
Home Smooth Cardiac Skeletal
Closely fit together No striations Single nuclei Involuntary Walls of hollow
organs
Home Muscular Cardiac Skeletal
Branch out Found in walls of
heart Propel blood
involuntarily
Home Muscular Smooth Skeletal
Long cylinder cells
Stripes Many nuclei Voluntary
movements Attach to bones
Home Muscular Smooth Cardiac
Branched Neurons Transports Signals Found in brain,
spinal cord and peripheral nerves.
