Proximal phalangeal fractures are relatively common and may result in a great deal of disability. The mechanism of action usually results from a direct perpendicular force, a rotary force, or hyperextension of the finger. The physical examination is the same as that for distal phalangeal fractures (see above).
Dense irregular connective tissue are tissue types found in the dermis. subcutaneous layer. The Dermis of the skin is composed of Dense Irregular Connective Tissue. skin tissue.
The dermis is the deeper skin layer consisting of two layers: the papillary and elastic, both containing collagen. Blood vessels (capillaries) and nerves are found in this layer. The principle structural component of the dermis is the protein collagen, produced by fibroblasts dispersed throughout the dermis.kin thickness varies and is on average 1mm thick; the thinnest on eyelids at 0.5mm and the thickest at 1.5mm on the palms and soles. Skin consists of multiple layers (stratified), epidermis, dermis and hypodermis (deepest layer).
