Connective Tissue Flashcards
Formed by three classes of components: cell, fibers, and ground substance.
Connective tissue
Major constituent of connective tissue
Extracellular matrix (ECM)
Connective tissue cells
Blast
Cytes
Clasts
What are the protein fibers?
(CRE)
Collagen fibers
Reticular fibers
Elastic fibers
Fibers consist of collagen, which is the most abundant protein in the body.
Collagen fibers
Fibers which are very strong and flexible, like microscopic ropes but quite inelastic.
Collagen fibers
Very fine, short collagen fibers that branch to form supporting network
Reticular fibers
This protein has the ability to return to its original shape after being stretched or compressed, giving tissue an elastic quality
Elastin
most abundant type of collagen
Type I collagen
Collagen found in connective
tissues, tendons, ligaments, bone, teeth, and the dermis of the skin.
Type I collagen
Collagen found in hyaline cartilage.
Type II collagen
It constitutes reticulin fibers. These fibers play a role in the structural component in the liver, bone marrow, and lymphoid
organs.
Type III collagen
Collagen found in basement membranes. Does not form fibers or fibrils
Type IV collagen
3 types of connective tissue
Embryonic CT
Connective tissue proper
Specialized CT
It is the shapeless background against which cells and collagen fibers are seen in the light microscope.
Ground Substance
Two types of Embryonic Connective Tissues
Mesenchyme
Mucoid
Types of Connective Tissue Proper
Loose (Areolar)
Dense Irregular
Dense Regular
What are the 5 types of Specialized Connective Tissue
(ARC BB)
Adipose
Reticular
Cartilage
Bone
Blood
It is an embryonic tissue formed by elongated undifferentiated cells, the mesenchymal cells, that formed the different connective
tissues.
Mesenchyme
The mesenchyme develops mainly
from the middle layer of the
embryo called?
Mesenchyme = Mesoderm
Mesoderm
Random fibroblasts and collagen fibers in viscous matrix.
Mucoid Connective Tissue
Supports and cushions large blood vessels
For example,
Matrix of fetal umbilical cord (Wharton’s Jelly)
Pulp cavities of young teeth
Mucoid Connective Tissue
It consists of relatively few protein fibers that form a lacy network, with numerous spaces filled with ground substance and fluid.
Loose Connective Tissue
Other term for loose connective tissue
Areolar tissue
