The statement regarding the phalanges of the hand being true is that each phalanx has a base, shaft, and head. This structure is consistent across all phalanges in the fingers. Each phalanx is divided into three distinct parts: the proximal end, known as the base; the middle section known as the shaft; and the distal end, termed the head. This anatomical structure allows for the articulation with adjacent bones, facilitating movement and function in the fingers.

Other options present details that do not accurately represent the anatomy of the phalanges. For instance, the phalanges do connect to the carpals through their proximal ends, hence the statement claiming they do not connect is inaccurate. While most fingers have three phalanges (proximal, middle, and distal), the thumbs are an exception, having only two, which contradicts the notion that all phalanges in hand anatomy are structured in three segments per finger. Lastly, while ligaments connect the bones, they are not the sole means by which phalanges are connected, as these bones also articulate through joints.
