Generation of a Motor Nerve Organoid with Human Stem Cell-Derived Neurons

open access: yesStem Cell Reports, 2017
Summary: During development, axons spontaneously assemble into a fascicle to form nerves and tracts in the nervous system as they extend within a spatially constrained path. However, understanding of the axonal fascicle has been hampered by lack of an in

Muscle Architecture Adaptations to Static Stretching Training: A Systematic Review with Meta-Analysis

open access: yesSports Medicine - Open, 2023
Background Long-term stretching of human skeletal muscles increases joint range of motion through altered stretch perception and decreased resistance to stretch. There is also some evidence that stretching induces changes in muscle morphology.

Ultrasound as a Tool to Study Muscle–Tendon Functions during Locomotion: A Systematic Review of Applications

open access: yesSensors, 2019
Movement science investigating muscle and tendon functions during locomotion utilizes commercial ultrasound imagers built for medical applications. These limit biomechanics research due to their form factor, range of view, and spatio-temporal resolution.

Investigating the Effect of Aging on the Viscosity of Tendon Fascicles and Fibers

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
In the current work, we investigate the effect of aging on the viscosity of tendon subunits. To that scope, we make use of experimental relaxation curves of healthy and aged tendon fascicles and fibers, upon which we identify the viscosity parameters ...

Nerve Ultrasound in Traumatic and Iatrogenic Peripheral Nerve Injury

open access: yesDiagnostics, 2020
Peripheral nerve injury is a potentially debilitating disorder that occurs in an estimated 2–3% of all patients with major trauma, in a similar percentage of medical procedures.

The force-length relation of the young adult human tibialis anterior [PDF]

open access: yesPeerJ, 2023
Background Knowledge of the muscle’s lengths at which maximum active isometric force is attained is important for predicting forces during movement. However, there is limited information about the in vivo force-length properties of a human muscle that ...

Pattern of fibre type distribution within muscle fascicles of pigs (Sus scrofa domestica)

open access: yesCzech Journal of Animal Science, 2007
In order to determine breed differences in the fascicle structure of skeletal muscles, longissimus dorsi muscles (LD) and semimembranous muscles (SM), Duroc (D), Large White (LW), German Landrace (GL) and Swedish Landrace (SL) boars were analyzed.

Energy transfer in reactive movements as a function of individual stretch load

open access: yesFrontiers in Physiology, 2023
Background: By directly recording electromyographic activity profiles and muscle-tendon interaction, this study aimed to elucidate the mechanisms why well-trained track and field athletes (experts) are able to outperform untrained individuals without ...

Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae) [PDF]

open access: yes, 2014
Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood ...
