Histology
- The study of
the normal
structure of
tissues
- Tissue:
- A group of
structurally and
functionally
related cells &
their ECM that
perform a
common function
- 2 basic components
- Extra Cellular
Matrix (ECM)
- 2 Main
Components
- Ground Substance
- Protein Fibers
- Collagen Fibers
- Elastic Fibers
- Reticular Fibers
- Interweave to form
mesh
- supports cells
- spleen: help trap
foreign substancds
- supports cells
- Interweave to form
mesh
- stretch to 1.5
times their
length -
Distensibility
- Return to
resting -
elasticity
- Return to
resting -
elasticity
- Reticular Fibers
- resembles entwined
pieces of steel cable
- Appear White in tendons
- Appear White in tendons
- Resistant to tension
- Elastic Fibers
- Collagen Fibers
- 3 Families of
Macromolecules
- Ions
- Water
- nutrients
- ECF
- ECF
- nutrients
- Water
- Glycosaminoglycans
(GAG's)
- Proteoglycans
- Bottle Brush Shape
- ECM Firmer
- Barrier to Diffusion of
Substances
- Barrier to Diffusion of
Substances
- ECM Firmer
- Bottle Brush Shape
- Glycoproteins
- Cell-adhesion
molecules (CAM)
- Glue Cells to their
place in ECM
- Glue cells
to each
other
- Glue cells
to each
other
- Glue Cells to their
place in ECM
- Cell-adhesion
molecules (CAM)
- negative sugars
in GAG attract
Cations in ECM
- Creates
concentration
gradient that
causes
Osmosis of
water out of
the cell &
blood vessels
- Water in ECM helps it
resist compression
- Water in ECM helps it
resist compression
- Creates
concentration
gradient that
causes
Osmosis of
water out of
the cell &
blood vessels
- Proteoglycans
- Ions
- 3 Functions
- provides
strength to
resist ensile
and
compressive
forces
- holds cells
in their
proper
place
- regulates miosis
and survival of
cells within a tissue
- provides
strength to
resist ensile
and
compressive
forces
- Protein Fibers
- Ground Substance
- 2 Main
Components
- Cells Related in
Structure and function
- Extra Cellular
Matrix (ECM)
- 4 Types of Tissues
- Epithelial Tissue
- Connective Tissue
- Nervous Tissue
- Muscle Tissue
- Muscle Tissue
