2020年4月2日 · Bat Anatomy 101: The Various Bones of The Wing & Skeleton. When it comes to the anatomy of bats, the most fascinating part is undoubtedly their wings. Made up of a thin membrane of skin stretched over a network of bones, cartilage, and muscles, wings are incredibly strong and flexible, allowing these animals to fly with amazing agility.

Human, bird, and bat forearm bones include the humerus, ulna, radius, carpals, metacarpals, and phalanges. Can you identify these bones on the diagram below? While these organisms all have the same basic types of bones, the bones have been modified to have different functions.

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 origin of bat wings is most clearly revealed by their skeleton. Every element of that skeleton is clearly homologous with structures in the forelimbs of other mammals, and there is no question that bat wings evolved as a result of modifications to the forelimbs of their ancestors.

Bat wings are modified tetrapod forelimbs. Because bats are mammals, the skeletal structures in their wings are morphologically homologous to the skeletal components found in other tetrapod forelimbs.

2023年12月31日 · – Wings: The wings of‍ a bat are⁢ a unique ‌adaptation of the forelimbs, with a flexible membrane of skin stretched between elongated fingers. This membrane, called the patagium, allows bats to generate lift and propel themselves‌ through the air.

2016年1月28日 · Here, the bone structure of the wings is highlighted in the brown long-eared bat, Plecotus auritus. The majority of support for the wing is provided by the metacarpals, the first bones of the fingers – in humans, these bones form the fleshy part of the hand (see here).

... bat wing consists of three membranes (patagia): dactylopatagium, between the digits; plagiopatagium, between the fifth digit to the ankle; and the propatagium, a smaller membrane on the...

Background/aims: Wing skeletons of bats are uniquely specialized for flight, reflecting both evolutionary history and the need to maintain structural integrity while generating aerodynamic forces. Methods: We analyzed the anatomical structure of bat wing skeletons in the context of scaling patterns relative to other mammals, material properties ...
