Q

Collagen fibers

A

Most common fibers in connective tissue proper

Long, straight, and unbranched

Strong and flexible

Resist force in one direction

Ex: tendons and ligaments

Reticular fibers

A

Network of interwoven fibers(stroma)

Strong and flexible

Resist force in many directions

Stabilize functional cells and structures

Ex: sheats around organs

Q

Ground substance

A

Fluid to make sure the fibers stay in place

Is clear, colorless and viscous

Fills spaces between cells and slows pathogen movement.
