Tissue
Epithel-ial
Function
protection of underlining structures
Absorption of nutrients
Secretion of hormones and excretion
Coverage
Filtration
Structure
Has a apical (free) surface
Cells reproduce (quickly)
Has a basement membrane
made up of epithelial cells
3 major types
Complexity
Simple
One layer
3 shapes
Squomous
thin and fat
Its found in the skin.
Cuboidal
cube shaped
Its found in the pancreas, and glands.
Columnar
more tall than wide
Its found in the lining of the intestine, stomach, and colon.
stratified
More than one layer
nervous
Function
coordinating and to control many body activities
communications
Structure
Is made out of three different cells
Dendrites
Extensions, or processes, of the cytoplasm that carry impulses to the cell body.
The cell body
Transmit information between neurons and away from muscles and glands.
One axon
Transmit information between neurons and away from muscles and glands.
neurons
The cells considered to be the basis of nervous tissue.
glial cells
Provide support for an essential nervous system function.
3 major types
Interneurons
They connect spinal motor and sensory neurons.
Sensory neurons
Carries impulses from the receptor to the CNS.
Motor neurons
Transmit impulses from the spinal cord to skeletal and smooth muscles, and so directly control all of our muscle movements.
Connec-tive
Function
Supporting organs and cells
transporting nutrients and wastes
defending against pathogens
storing fat
repairing damaged tissues
Structure
non living material
extracellular matrix
Ground substance
Fibers
Fibers
Collagan
Strongest most abundant fiber
Reticular
Provide stroma to sustain the lymphoid organs
Elastic
Provides elasticity and resilience to the tissues.
4 major types
Blood
Bone
cartilage
A strong, flexible connective tissue that protects your joints and bones.
Connective tissue Proper
loose connective tissue
A cellular connective tissue with thin and relatively sparse collagen fibers.
dense connective tissue
Stabilize surrounding structures and maintain the structural framework in the body.
Fat
Provides insulation and fuel storage.
Muscle
Function
provides movement for the body parts.
Structure
muscle fibers
Fascicles
Composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.
3 major types
Skeletal
Providing structural framework and movement to the body.
Smooth
Thick and thin filaments that are not arranged into sarcomeres giving it a non-striated pattern.
Cardiac
The thick middle layer of the heart.
