3D hindlimb joint mobility of the stem-archosaur Euparkeria capensis with implications for postural evolution within Archosauria

open access: yesScientific Reports, 2020
Triassic archosaurs and stem-archosaurs show a remarkable disparity in their ankle and pelvis morphologies. However, the implications of these different morphologies for specific functions are still poorly understood.

State- and Condition-Dependent Modulation of the Hindlimb Locomotor Pattern in Intact and Spinal Cats Across Speeds

open access: yesFrontiers in Systems Neuroscience, 2022
Locomotion after complete spinal cord injury (spinal transection) in animal models is usually evaluated in a hindlimb-only condition with the forelimbs suspended or placed on a stationary platform and compared with quadrupedal locomotion in the intact ...

Combined Effects of Ketogenic Diet and Aerobic Exercise on Skeletal Muscle Fiber Remodeling and Metabolic Adaptation in Simulated Microgravity Mice. [PDF]

open access: yesMetabolites
Objective: Prolonged microgravity environments impair skeletal muscle homeostasis by triggering fiber-type transitions and metabolic dysregulation. Although exercise and nutritional interventions may alleviate disuse atrophy, their synergistic effects ...

Left-right side-specific endocrine signaling complements neural pathways to mediate acute asymmetric effects of brain injury

open access: yeseLife, 2021
Brain injuries can interrupt descending neural pathways that convey motor commands from the cortex to spinal motoneurons. Here, we demonstrate that a unilateral injury of the hindlimb sensorimotor cortex of rats with completely transected thoracic spinal

Pitx1 determines characteristic hindlimb morphologies in cartilage micromass culture. [PDF]

open access: yesPLoS ONE, 2017
The shapes of homologous skeletal elements in the vertebrate forelimb and hindlimb are distinct, with each element exquisitely adapted to their divergent functions.

First anatomical network analysis of fore- and hindlimb musculoskeletal modularity in bonobos, common chimpanzees, and humans [PDF]

open access: yes, 2018
Studies of morphological integration and modularity, and of anatomical complexity in human evolution typically focus on skeletal tissues. Here we provide the first network analysis of the musculoskeletal anatomy of both the fore- and hindlimbs of the two

Come together over me: Cells that form the dermatocranium and chondrocranium in mice

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Most bone develops either by intramembranous ossification where bone forms within a soft connective tissue, or by endochondral ossification by way of a cartilage anlagen or model. Bones of the skull can form endochondrally or intramembranously or represent a combination of the two types of ossification.

Hindlimb abnormality reduces locomotor performance in Pelobates cultripes metamorphs but is not predicted by larval morphometrics [PDF]

open access: yesHerpetozoa, 2019
Locomotor performance is a fundamental feature commonly related to many animals’ fitness. In most cases, locomotor performance is closely related to morphology of the structures responsible for it, which is therefore under strong selective pressure ...

Cancellous bone and theropod dinosaur locomotion. Part II—a new approach to inferring posture and locomotor biomechanics in extinct tetrapod vertebrates [PDF]

open access: yes, 2018
This paper is the second of a three-part series that investigates the architecture of cancellous bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous bone architectural patterns to infer locomotor biomechanics in extinct non-avian ...

Whole-mount imaging of the mouse hindlimb vasculature using the lipophilic carbocyanine dye DiI.

open access: yesBioTechniques, 2012
The availability of transgenic disease backgrounds and the accessibility of molecular research reagents have contributed to make the mouse ischemic hindlimb the model of choice for many studies of angiogenesis, and to investigate new treatments for ...
