Official Pittsburgh Pirates Cooperstown Collection Huntington Logo Shirt
Unlike insects and birds, which have relatively rigid wings that can move in only a few directions, a bat’s wing contains more than two dozen joints that are overlaid by a thin elastic membrane that can stretch to catch air and generate lift in many different ways. This gives bats an extraordinary amount of control over the Pittsburgh Pirates Cooperstown Collection Huntington Logo Shirt and I love this three-dimensional shape their wings take during flight. What is more, their wings have long muscles embedded in the skin, running front to back, and not attached to any bones. Scientists had suspected that these muscles probably helped shape the wings in flight, but evidence was lacking. Now, in experiments at Brown University with Jamaican fruit bats, investigators have found signs that the muscles do indeed contract on the downstroke when bats are flying. One more surprise are that bats’ stretchy bicep and tricep tendons are crucial for storing and releasing the energy the creatures require for takeoff.
