Connective Tissue

Common Characteristics
- Common Origin - mesenchyme
- Degrees of vascularity
- Extracellular matrix
Connective tissues are largely composed of a nonliving extracellular matrix that can take stress, abuse, and punishment that other tissues cannot.

Ground Substance
- Unstructured
- Interstitial fluid, cell adhesion proteins, proteoglycans

CARTILAGE
- Tension and. Compression
- Tough but flexible
- Avascular
- Nerve fibers
- Diffusion through connective tissue membrane
- Up to 80%water

CARTILAGE
- Avascular
- Lose ability to divide
- Calcify or ossify
- Chondrocytes die

Hyaline
- Gristle
- Most Abundant
- Glassy (hyalin = glass)
- Firm Support with some pliability
- Why is the function important in terms of location?

Hyaline Locations
- Articular cartilage
- Tip of Nose
- Connects ribs to sternum
- Embryonic skeleton
- Epiphyseal plates

Elastic
- Nearly identical to hyaline
- Elastin fibers
- Where need strength coupled with exceptional stretchability

Fibrocartilage
- Between hyaline and dense connective tissue
- Chondrocytes
- Collagen fibers
- Compressible, resists tension
- Strong support &a heavy pressure

BONE
- Osseous tissue
- Support
- Protection
- Cavities for storage
- Fat and blood
- More collagen
- Inorganic calcium salts

BLOOD
- Fluid within blood vessels
- No connection or support
- Matrix is plasma
- RBCs, WBCs
- Blood clotting "fibers"

AREOLAR FUNCTIONS
- Support and bind other tissues
- Hold body fluids
- Defend against infection
- Storing nutrients

AREOLAR
- Loose arrangement of fibers
- Means "small open space"
- Hyaluronic acid
- Edema

Adipose
- 90% Adipocytes
- Chickenwire appearance
- Nucleus displaced
- Richly vascularized
- 18-50% of a person's body weight
Photo by Leo Reynolds
Adipose Functions
- Shock absorber
- Insulation
- Energy storage
- Smaller deposits to supply local nutrient needs
- heart, lymph nodes, bone marrow

Dense regular
- White, flexivle structures with great resistance to tension
- Slightly wavy
- poorly vascularized
