Answer 17

binding, packing material

fascia and sheaths

Question 18

what are the primary characteristics of dense connective tissue>

Answer 18

dense collagen fibers arranged parallel to direction of force
strong and flexible
white and silvery

Question 19

what are the primary characteristic of supporting connective tissue

Answer 19

Question 20

what are the 3 types of cartilage and what are their purposes

Answer 20

hyaline cartilage
- reduces friction
- stiff and flexible support
- common cartilage

fibrous cartilage
-resists compression
-prevents bone-bone contact
-limits movement.

elastic cartilage
-support
-can be distorted without permanent damage
-returns to original shape.
