Ch. 5 Connective Tissue Flashcards
How is connective tissue you distributed in the body
Abundantly distributed it is the most abundant tight
What is the structure of connective tissue
Variety in structure
Mainly matrix
How is connective tissue divided and what are the different functions
Bind support and protect
Insulates in stores
Transportation and defense
From where does connective tissue originate
Mesoderm
Where will connective tissue never be found
On exposed body surface
What does connective tissue do
Gives internal support
Surround organs
Hold organs in place
Attaches organs to body wall
What does connective tissue contain
Blood vessels
What is it called when tissue has many blood vessels
Vascular
What does the connective tissue matrix consist of
Ground substances
Tissue fluid
Fibers
Describe the ground substance texture in the connective tissue matrix
Rubbery as in cartilage
Flexible
Soft and stretchable
Hard as a rock
Describe the tissue fluid in the connective tissue matrix
Clear and watery
Derived from blood liquid portion
Contains gases wastes and nutritional items
Describe the fibers of the connective tissue matrix
Long thin proteins
Provide strength and elasticity
What are the three types of matrix fibers
Collagen
Reticular
Elastic
Most abundant type holds muscle to bone
Collagen
Internal framework of soft organs
Basement membrane
Reticular matrix fiber
Stretchable
Skin blood vessels and lungs
Elastic matrix fiber
How many types of cells are present in connective tissue and name them
2
Fibroblasts
Fibrocytes
Secretion and maintenance
Fibrocytes
Defend against infection aid in healing
Fibroblasts
What is found in fibrous connective tissue
All have matrix with some collagen fibers and blood vessels found in all types
Where is loose connective tissue distributed and where does it wrap
Widely distributed in adults
Wraps around internal organs, blood vessels, muscles and nerves
Describe the structure of loose connective tissue
Greater flex
Little strength
Describe dense connective tissue
More collagen fibers
Strength
Tendons and ligaments
Describe elastic connective tissue
Numerous bundles
Stretchability
Walls of organs
Stomach. Lungs, vessels,vocal cords
Describe reticular connective tissue
Network of fibers (collagen)
Internal framework for soft organs
Liver,spleen, lymph nodes, tonsils
Specialized connective tissue
Diverse
Adipose ( holds things together)
Adipose connective tissue
Functions for storage
Found under skin; protection
Few fibers
Cells that store fat
Adipocytes
Removal of adipose tissue
Liposuction
Describe cartilage
Many collagen fibers
Gives strength; flexibility
Lacks blood vessels, nerves, heals slowly
Secretes cartilage matrix
Chondroblasts
Found in small openings called lacunae
Produce the fibers and the tough, gristle like ground substance of cartilage
Chondrocytes
Dense connective tissue
Wrapped around cartilage
Blood vessels nourish the cartilage
Perichondium
Matrix consistency of connective tissue
Vary from liquid to rigid
Structure and composite of connective tissue
Lot of matrix and less cells
Types of connective tissue
Fibrous
None
Cartilage
Blood
