“…We sorted the muscle arrays into five groups that are broad enough to be applicable across Chiroptera but fine enough to resolve differences in architectural features of the array. The anatomical names we propose overlap substantially with previous nomenclature and we detail the relationship between the names we propose here and prior usage (Table ) (Humphry, ; Schöbl, ; Macalister, ; Maisonneuve, ; Morra, ; Schumacher, ; Vaughan, ; Mori, ; Norberg, ). Where we suggest name modifications, we expand the generality of the site of origin to capture the diversity of muscle form across Chiroptera, and describe the insertion site consistently as the ‘patagium’, illustrated by our suggested replacement of ‘tarso‐cutaneo’ with ‘tibiopatagialis’.…”

“…Over nearly 150 years, many authors have described the muscles of the wing membrane, but the naming and categorization schemes that have been employed to date are inconsistent and, in some cases, contradictory (Table ; Humphry, ; Schöbl, ; Macalister, ; Maisonneuve, ; Morra, ; Schumacher, ; Vaughan, ; Mori, ; Norberg, ). Research and discussion on the subject of these muscles requires clear, unambiguous communication, and the nomenclature, definitions, and hypotheses of homology we propose should assist future dialog.…”

“…Where we suggest name modifications, we expand the generality of the site of origin to capture the diversity of muscle form across Chiroptera, and describe the insertion site consistently as the ‘patagium’, illustrated by our suggested replacement of ‘tarso‐cutaneo’ with ‘tibiopatagialis’. We retain the name ‘coracopatagiales’ because the origin for this muscle group has been consistently described as the coracoid process of the scapula, although we can only confirm that the origin is in the vicinity of the axilla without detailed and destructive dissections (Maisonneuve, ; Morra, ; Vaughan, ). It is possible, however, that there is variation in this character that has yet to be explored.…”

“…Little is known about the details of morphology or function of the other wing membrane muscles. Various muscles have been observed in multiple species, and are described in several classic anatomical studies of bats, albeit with inconsistent nomenclature (Humphry, ; Schöbl, ; Macalister, ; Maisonneuve, ; Morra, ; Schumacher, ; Vaughan, ; Mori, ).…”

Diversity in the organization of elastin bundles and intramembranous muscles in bat wings

2017

Unlike birds and insects, bats fly with wings composed of thin skin that envelops the bones of the forelimb and spans the area between the limbs, digits, and sometimes the tail. This skin is complex and unusual; it is thinner than typical mammalian skin and contains organized bundles of elastin and embedded skeletal muscles. These elements are likely responsible for controlling the shape of the wing during flight and contributing to the aerodynamic capabilities of bats. We examined the arrangement of two macroscopic architectural elements in bat wings, elastin bundles and wing membrane muscles, to assess the diversity in bat wing skin morphology. We characterized the plagiopatagium and dactylopatagium of 130 species from 17 families of bats using cross-polarized light imaging. This method revealed structures with distinctive relative birefringence, heterogeneity of birefringence, variation in size, and degree of branching. We used previously published anatomical studies and tissue histology to identify birefringent structures, and we analyzed their architecture across taxa. Elastin bundles, muscles, neurovasculature, and collagenous fibers are present in all species. Elastin bundles are oriented in a predominantly spanwise or proximodistal direction, and there are five characteristic muscle arrays that occur within the plagiopatagium, far more muscle than typically recognized. These results inform recent functional studies of wing membrane architecture, support the functional hypothesis that elastin bundles aid wing folding and unfolding, and further suggest that all bats may use these architectural elements for flight. All species also possess numerous muscles within the wing membrane, but the architecture of muscle arrays within the plagiopatagium varies among families. To facilitate present and future discussion of these muscle arrays, we refine wing membrane muscle nomenclature in a manner that reflects this morphological diversity. The architecture of the constituents of the skin of the wing likely plays a key role in shaping wings during flight.

Assessment of the Hindlimb Membrane Musculature of Bats: Implications for Active Control of the Calcar

The Anatomical Record

The striking postcranial anatomy of bats reflects their specialized ecology; they are the only mammals capable of powered flight. Bat postcranial adaptations include a series of membranes that connect highly-modified, or even novel, skeletal elements. While most studies of bat postcranial anatomy have focused on their wings, bat hindlimbs also contain many derived and functionally important, yet less studied, features. In this study, we investigate variation in the membrane and limb musculature associated with the calcar, a neomorphic skeletal structure found in the hindlimbs of most bats. We use diffusible iodine-based contrast-enhanced computed tomography and standard histological techniques to examine the calcars and hindlimb membranes of three bat species that vary ecologically (Myotis californicus, a slow-flying insectivore; Molossus molossus, a fast-flying insectivore; and Artibeus jamaicensis, a slow-flying frugivore). We also assess the level of mineralization of the calcar at muscle attachment sites to better understand how muscle contraction may enable calcar function. We found that the arrangement of the calcar musculature varies among the three bat species, as does the pattern of mineral content within the calcar. M. molossus and M. californicus exhibit more complex calcar and calcar musculature morphologies than A. jamaicensis, and the degree of calcar mineralization decreases toward the tip of the calcar in all species. These results are consistent with the idea that the calcar may have a functional role in flight maneuverability. Anat Rec, 301:441-448, 2018. © 2018 Wiley Periodicals, Inc.
