Commentary: Unilaterally absent palmaris longus: A golden opportunity

Morphology of human palmaris longus tendon.

A systematic morphological investigation of human palmaris longus tendons by polarisation microscopy and low angle x-ray diffraction is reported. It is shown that contrary to some previously reported observations, and in common with other tension bearing soft collagenous tissues, the fibres in this tendon are crimped. A new method of preparation of the tissue enabling one to see directly the cr...

Neuroanastomosis of orthotopically transplanted palmaris longus muscles.

Palmaris longus (PML) muscles of rhesus monkeys were transplanted, with or without anastomosis of the median nerve, to the nerve stump of the autograft. Because PML autografts revascularize spontaneously, vascular anastomoses were not performed. Muscle fibers regenerated in all autografts with neuroanastomosis, but in only three of eight autografts without neuroanastomosis. Five autografts with...

A Case of the Bilateral Duplicate Palmaris Longus Muscles Coupled with the Palmaris Profundus Muscle

The palmaris longus muscle is one of the most variable muscles in human anatomy. During a routine anatomical dissection for medical students at Tottori University, we found duplicate palmaris longus muscles in the bilateral forearms together with the palmaris profundus muscle in the right forearm. The bilateral aberrant palmaris longus muscles were observed at the ulnar side of the palmaris lon...

A golden opportunity, squandered.

Even when used to make products of negligible risk and that contribute significantly to public health, recombinant DNA technology (a.k.a. ‘genetic modification’, or GM) applied to agriculture has a tough row to hoe. ‘Golden Rice’, which has been enriched by the addition of genes that allow rice to synthesize b-carotene (the precursor of vitamin A) in its edible endosperm, has endured resistance...
