Three‐dimensional digital analysis of musteloid masticatory muscle architecture

The Anatomical Record, EarlyView.
Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Passive Muscle-Tendon Unit Gearing is Joint Dependent in Human Medial Gastrocnemius

Frontiers in Physiology, 2016
Skeletal muscles change length and develop force both passively and actively. Gearing allows muscle fibre length changes to be uncoupled from those of the whole muscle-tendon unit.

Fascicle angle and fascicle length estimates of TimTrack, UltraTrack and manual observers for two typical example trials.

, 2022
Fascicle angle and -length changed considerably during both movements, captured by manual observers (red dots), TimTrack (blue lines) and UltraTrack (yellow lines). Upper row: Two repetitions of a range-of-motion ankle movement from dataset 2. Lower row:

Bite force estimates and morphological correlations of jaw muscles in parrots

The Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Multiscale hamstring muscle adaptations following 9 weeks of eccentric training

Journal of Sport and Health Science
Background: Eccentric training, such as Nordic hamstring exercise (NHE) training, is commonly used as a preventive measure for hamstring strains. Eccentric training is believed to induce lengthening of muscle fascicles and to be associated with the ...

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Partial bodyweight-supported squats elicit eccentric contraction of the thigh muscles

BMC Musculoskeletal Disorders
Purpose The study aimed to investigate how different levels of supporting forces during the squat exercise at a self-selected speed, along with different knee angles, affect fascicle length, pennation angle, and muscle activation for healthy young ...

Iliac Attachment of the Psoas Major Muscle: Anatomical Study of a Novel Muscle Attachment

Clinical Anatomy, EarlyView.
ABSTRACT The iliopsoas muscle is important functionally and is often encountered during various surgical procedures. During routine cadaveric dissection, a previously undescribed muscular structure was located deep to the iliacus muscle and coursed inferomedially to merge with the posterior aspect of the psoas major, running over the iliopectineal ...

Electroclinical features and dynamic network connectivity of orbitofrontal epilepsy

Epilepsia, EarlyView.
Abstract Objective Orbitofrontal epilepsy (OFE) is rare and underrecognized. This study aims to characterize electroclinical features and dynamic network connectivity of OFE and subtypes. Methods We retrospectively analyzed 17 patients with OFE who underwent stereoelectroencephalographic (SEEG) electrode implantation and epilepsy surgery at our center.
