(d)
Connective tissue proper: dense connective tissue, dense regular
Description:
Primarily parallel collagen fibers;
a few elastic fibers; major cell type is the
fibroblast.
Function:
Attaches muscles to bones or to
muscles; attaches bones to bones; withstands
great tensile stress when pulling force is
applied in one direction.
Location:
Tendons, most
ligaments, aponeuroses.

(e)
Connective tissue proper: dense connective tissue, dense irregular
Description:
Primarily irregularly arranged
collagen fibers; some elastic fibers; fibroblast
is the major cell type.
Function:
Withstands tension exerted
in many directions; provides structural
strength.
Location:
Fibrous capsules of organs and
of joints; dermis of the skin; submucosa of
digestive tract.
