Furrows and dermal ridges of the hand in patients with alcohol embryopathy
Abstract:
Palmar creases and dermal ridge patterns of 34 patients with alcohol embryopathy are compared with 470 healthy individuals. In alcohol embryopathy several typical deviations were noted. Palmar Creases. The interdigital part of the distal palmar crease is generally sharply bent, the proximal transverse crease is hypoplastic or missing, the thenar crease is commonly well marked. Simian creases and bridged palmar creases are more common in patients with alcohol embryopathy than in healthy individuals. Ridge Patterns of the Palm. The main line D coming from triradius d in patients with alcohol embryopathy mostly shows a low type of ending in the fourth interdigital area; in this area loops are twice as common as in healthy individuals. Patterns of the Fingertips. No deviations were noted in the distribution of whorls and loops, but virtually no arches were observed in patients with alcohol embryopathy. These anomalies suggest embryonic damage in the twelfth week of gestation.

Papillary 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.

The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
