WebWoodpecker Skull. Diagram of a woodpecker skull showing the hyoid bone wrapping around the skull. This extremely elongated bone is one of several evolutionary adaptations that protect a woodpecker's brain from damage when it drums on hard surfaces. Photo courtesy of Geoffrey E. Hill. Web5 apr. 2024 · Due to the large contact area between the hyoid bone and the head, and the special structures including the skull and cancellous bone, the excellent impact resistance of the woodpecker's head was enhanced obviously . Inspired by the damping mechanism of the woodpecker, there are also a number of engineering applications [34,35,36,37,38].

The hyoid bone is derived from the lower half of the second gill arch in fish, which separates the first gill slit from the spiracle, and is often called the hyoid arch. In many vertebrates, it also incorporates elements of other gill arches, and has a correspondingly greater number of cornua. Amphibians and reptiles may have many cornua, while mammals (including humans) have two pairs, and birds onl… WebWoodpeckers avoid brain injury while they peck at trees up to 20 Hz with speeds up to 7 …

WebThe bending resistance is low at the posterior section of the hyoid bones, indicating that this region has a high degree of flexibility to absorb impact. These new structural findings can be applied to further studies on the energy dissipation of the woodpecker during its drumming behavior, and may have implications for the design of engineered impact …
Webb) A woodpecker has an extended part of a tongue called the hyoid bone. It goes from the jaws to the back portion of the skull, as shown in Fig. 1. The hyoid bone acts as a buffer and retards the shock into the skull bone. c) The bone in the front of the skull bone is porous.
