翼龙的翅膀由一个狭窄的翼膜或翼膜组成，主要由超长的前肢支撑和控制，但也附着在身体的侧面和后肢上。翼膜由一薄层可伸展的皮肤组成，具有细长的结构纤维（=放线原纤维），呈放射状排列。放线原纤维的功能被不同地解释为1）防止不必要的翼膜拍打，2）使翼膜弯曲，将空气动力学载荷向前和近侧传递到掌骨和前臂，以及3）使翼膜向弦向伸展。只有最后的解释与现有数据一致。放线原纤维抵抗纵向压缩，以扩展翼膜弦向，重定向展向张力在近端翼膜的弦向张力在远端翼膜，并允许紧凑的折叠。
The wings of pterosaurs consisted of a narrow wing membrane or patagium primarily supported and controlled by the hyperelongate forelimb, but also attaching to the side of the body and the hindlimb. The patagium consisted of a thin sheet of extensible skin with slender structural fibers (=actinofibrils) arranged in a posterodistally radiating pattern. The function of the actinofibrils has been variously interpreted as 1) to prevent unwanted flapping of the patagium, 2) to camber the patagium, transferring aerodynamic loads anteriorly and proximally to the metacarpus and antebrachium, and 3) to spread the patagium chordwise. Only the last interpretation is consistent with the available data. The actinofibrils resisted longitudinal compression so as to spread the patagium chordwise, to redirect spanwise tension in the proximal patagium as chordwise tension in the distal patagium, and to permit compact folding.
