Figure 4-5A.
A representation of collagen ±
bers in loose
connective tissue.
Collagen ±
bers
are fl
exible but impart strength to the tissue.
They are arranged loosely, without a def nite orientation in
loose connective tissue.

Loose connective tissue
, also called
areolar connective tissue
, is
shown in a mesentery spread. In this tissue preparation, both col-
lagen f
bers and elastic f
bers are visible. The
elastic ± bers
are thin
strands stained deep blue, and
collagen ±
bers
are thick and stained
purple.
Fibroblasts
are seen among the f
bers.

A representation of collagen ± bers in dense
connective tissue.
Interwoven bundles oF
collagen ± bers
interspersed with
elastic ±
bers
are illustrated here. These f
bers are tightly
packed together in dense connective tissue.

An example oF
collagen
± bers
in the dense irregular connective tissue oF
the dermis oF the skin is shown. Both collagen
f bers (
pink
) and
elastic
± bers
(
black
) are present. Collagen f bers predominate in dense irregu-
lar connective tissue. They are arranged in thick bundles tightly packed
together in a nonuniForm manner.
