What Are the Wings of a Bat Like? Structure and Flight Features
Modified forelimb bones are the primary skeletal elements that support the bat’s flight membrane. The humerus is shortened relative to the forearm, allowing a compact shoulder joint that tolerates rapid, repetitive motion. The radius and ulna are elongated and partially fused, creating a rigid yet flexible support for the wing’s leading edge.. Date latest changes:
