Morphology of the dorsal phalangeal connective tissue body
1Department of Anatomy, University of Cologne, Germany.
Background:
The connective tissue body of the dorsal finger is partitioned by multiple horizontal lamellae derived from expansions of intercellular spaces. These connective fibres are involved in providing gliding spaces for the extensor apparatus, and they formed spreading rooms of infection processes.
Methods:
In order to describe the topographical histological and histochemical behavior of cellular and intercellular elements of the border lamellae of the dorsal aponeurosis of the fingers, a modified method of Epoxid resin embedding technique without pre-infiltration is used.
Results:
The bordering elements of the connective tissue lamellae described in this investigation are especially well defined in the region of the dorsal aponeurosis. The morphological examinations show that both the expansions of the intercellular space as well as defined fibrocytic cellular elements function in a manner equivalent to a synovial membrane of tendon sheaths.
Conclusions:
Saving or reconstructing these structures appears to be of importance in preventing for adhesive disorders of finger motion following surgical intervention in this region.

01:20Embryonic Connective Tissues
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development. Mesenchyme is...

Adipose Tissue
Adipose tissue consists primarily of fat storage cells called adipocytes and little extracellular matrix. A large number of capillaries present within adipose tissue allow rapid mobilization of lipid molecules. White adipose tissue is...

Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...
01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
