Topic: Patagium


In the News (Sat 28 Nov 09)

  
  Patagium
The patagium is a furred membrane of skin, stretching from the fore leg to the hind leg.
Underneath the skin of the patagium lay long thin muscle groups that control some of its movement, and along the edge lies a group of intertwined muscle that serves to hold the skin flaps in various degrees of tautness as required during its glide.
The patagium attaches to the fore leg via the styliform cartilage (see image at right), a rod-like appendage that allows the patagium to be extended further than would be the case without such a feature, thereby increasing the area of the leading edge, and the total area of the airfoil.

  Wing Anatomy
The patagium stretches between the fingers, connects the fore and rear limbs, and even extends between the legs (incorporating the tail) of the bat.
The bones of the arm and the four fingers primarily support and manipulate the patagium.
The hindlimbs are attached at the hip of the bat at a 90 degree rotation, pointing the legs sideways and the knees backward.

 Spongaster tetras tetras Ehrenberg
A completely enveloping patagium usually makes the central spheres difficult to see, and, at best, 5 concentric rings can be recognized; the "arms" appear merely as dark patches.
Patagium is, for the most part, a dense irregular spongy meshwork with small subcircular pores, but around the "arms" bars become thicker and 3-bladed.
Patagium may be depressed slightly around the central structure, but at its periphery its thickness is ~0.25 the length of the sides of the square (Nigrini, 1967).

 Draco Cyanopterus
The ventral surface of the patagium and tail is yellow in females, salmon in males, in both sexes either immaculate or with a few minute, widely scattered fl spots.
The same color that occurs on the ventral patagium may also be present as a wash down the middle of the chest and abdomen.
In males, the dorsal patagial pattern is composed of large pale cream spots within a thin, dark brown to fl reticulum over the proximal one—third of the patagium, but distally there are 4—6 large patches of naked skin (without scales) that are vivid chartreuse in coloration; the green patches appear ultramarine blue in preserved specimens.

The patagium consists of a loose flap of skin that is opened when the animal extends its limbs and sometimes its tail.
Instead of having one large patagium supported by its ribs, the flying gecko has small skin flaps along its limbs, torso, tail, and head.
Even stranger than the gliding lizards is the Malayan flying frog which glides using the membranes between the toes of its limbs, and small membranes located at the heel, the base of the leg, and the forearm.

 Morphology of the Chiroptera
Unlike birds and pterosaurs, in which the wing is supported by the bones of the arm and one finger, a bat's wing membrane, or patagium, is supported by the arm and by four highly elongated fingers (hence the name Chiroptera, or "hand-wing," for the bats).
The patagium extends all the way around to the bat's hind legs and tail, where it forms a flap called the uropatagium, supported by specialized foot bones called calcars.
Not only does the uropatagium help the bat fly and maneuver, it is often used to sweep prey, such as insects on the wing, into the bat's mouth while the bat is in flight.

 Amphirhopalum ypsilon Haeckel
In some specimens a patagium is present around the central structure and arms, sometimes with 4 or 5 chambered rows, concave inwards; sometimes simply a spongy mass.
It seems probable that a complete patagium (i.e., on a fully developed specimen) might surround the whole basic shell structure, but in all specimens examined the patagium had developed only between the 2 main arms and around the central structure.
Specimens from the upper parts of the cores examined [late Quaternary] average four or five proximal chambers on the forked arm before it bifurcates.

A conspicuous feature of the extended wing is the patagium, the fold of skin which extends from the upper arm along the entire lower arm to the wrist.
The patagium is essential because it presents a flattened plane to the airstream, and also increases the surface area of lift in the wing.
There is also a smaller fold of skin extending from the upper arm to the trunk, called the humeral patagium.

 A Flying Dragon Roaming the Air In Dinosaur Times - Another lizard with ribbed patagium - Softpedia
The fossil was discovered by Xing Xu at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, China and his team in northeastern China's Liaoning Province, a site that has delivered a trove of feathered dinosaurs and early bird remains during the last years.
The fossil's membrane is in a half-open position, due to the folding of the wing after the lizard's death.
The lizard’s patagium shares some similarities with the wings of modern birds, indicating it was somehow more agile in the air than modern flying dragons are (but still, not as agile as a bird).
