fibroblasts (8) in transverse section.

Between the large collagen bundles are the interfascicular connective

tissue (2) partitions. These partitions contain blood vessels, an arteriole and
venules (6), nerves, and, occasionally, the sensitive pressure receptors Pacinian
corpuscles (9).

Also illustrated on the left side of the figure is a transverse section of several
skeletal muscle fibers (4). These are adjacent to the tendon but are separated

from it by a connective tissue partition. Note that the nuclei (5) of skeletal
muscle fibers (4) are located on the periphery of the fibers, whereas the
fibroblasts (1, 8) are located between bundles of collagen fibers (3, 7).

FIGURE 5.13 | Adipose Tissue: Intestine

A section of intestinal mesentery is illustrated, in which accumulations of

adipose (fat) cells (4, 8) are organized into adipose tissue. The connective tissue
(9) that surrounds the adipose tissue is covered by a simple squamous epithelium
called mesothelium (10).

Adipose cells (4, 8) are closely packed and separated by thin strips of

connective tissue septa (3), in which are compressed fibroblasts (7), arterioles
(1), venules (2, 6), nerves, and capillaries (5).

Individual adipose cells (4) appear as empty cells because the fat was
dissolved by chemicals during preparation of the tissue. The adipose cell nuclei
(8) are compressed to the peripheral rim of the cytoplasm, and, in certain

sections, it is difficult to distinguish between fibroblast nuclei (7) and adipose
cell nuclei (8).
