A

mostly straight fibers not much ground substance. many Collagen fibers few elastin fibers main cell type is fibroblasts

25
Q

Connective Tissue Proper - Dense Regular // Function

A

Attaches muscles to bones or to muscles; attaches bones to muscles and has a great tensile strength from force in one direction (slight elaciticty 20 percent elastic fibers)

26
Q

Connective Tissue Proper - Dense Regular // Location

A

tendons, ligaments, aponeuroses

27
Q

Connective Tissue Proper - Dense Irregular // Description (main cell type and fiber type and amounts)

A

Irregularly arranged collagen fibers; w some elastic fibers (20-30 percent) and major cell type is fibroblast
