Arachnodactyly
Long spider-like fingers and toes, a frequent finding in Marfan syndrome, a heritable disorder of connective tissue.
'Arachnodactyly' is derived from the Greek 'arachne' (spider) and 'daktylos' (finger).
The Greek word was derived from the name 'Arachne,' a maiden in Greek mythology whom the goddess Athena turned into a spider after the girl, a skilled weaver, challenged Athena to a weaving contest.
