It an oil painting on canvas and features a reclining nude woman with her back to the viewer, with a tree branch in the background.

The model is actress Lisa Coleman, who attended Uglow's studio one to three times a week during the period, and reflected positively on her experience.

[16] The study was purchased by Hamish Parker from Marlborough Fine Art and later accepted by the UK Government under the Cultural Gifts Scheme and allocated to the British Museum.

[17] The Museum's catalogue record describes the content as a "reclining nude female figure with her back to the viewer, framed in a rectangle".

[19] Uglow regarded his Nude with Green Background (1964–65) as one of his first "really serious" paintings, and remarked that "You can see the easy movement from there to the back view of Articulation, very simple, I hope so.

[11] Coleman commented that "I treasure it as a lesson in the concept that he did not paint to produce pictures, but that they were by-products of his quest to capture the perfect fall of light", and that, despite being naked, she felt fully comfortable, due to "being viewed in a completely different way from how society normally judges the female form".

[28] Uglow similarly claimed that he did not distinguish between painting a live model as against another subject; this assertion was challenged by critic Adrian Searle.

[29] Martin Gayford of The Daily Telegraph felt that despite the long time Uglow took to complete his paintings, they were "fresh".

[25] Gayford argued that reflecting reality in a truthful way in a painting was a painstaking process; he commended "the softly rounded forms of the model's lower back and bottom" represented by "flat patches of mauve, pinky-grey and buff" in Articulation.

[25] Tim Hilton named Uglow "Best Artist of the Year" in his retrospective article in The Independent; the single image included was of Articulation.

[29] Searle complained about the emphasis in the paintings on the difficulty of producing them and remarked that "the act of looking and recording is presented as a joyless test".
