Yn anatomeg dynol, diffinir yr arddwrn fel 1) y carpws neu'r esgyrn carpalaidd, y cymhlyg o wyth asgwrn sy'n ffurfio'r segment procsimol esgyrnol yn y llaw;^[1]^[2] (2) cymal yr arddwrn neu'r cymal radio-carpol, y cymal rhwng y radiws a'r carpws;^[2] a'r (3) ardal anatomegol sy'n amgylchynnu'r carpws gan gynnwys y rhannau distal asgwrn yr elin a rhannau procsimol y metacarpws neu'r pump asgwrn metacarpal a'r cyfres o gymalau rhwng yr esgyrn hyn, a gyfeirir atynt fel 'cymalau'r arddwrn.^[3]^[4] Mae'r ardal hon hefyd yn cynnwys y twnel carpal, y blwch snisin anatomegol, plygydd retinacwlwm, a'r estynnydd retinacwlwm.
