A Rare Anomaly of the Long Head of the Biceps Brachii Muscle

Journal of Gandaki Medical College, 2018
Introduction: Biceps brachii is a muscle of arm which brings about supination when fore-arm is flexed and flexion of elbow joint. Proximally it is attached with two heads: long and short heads.

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Electromyographic Activation of Flexed Arm Circumference, With or Without Contralateral Opposition

Biomechanics
Flexed and tensed arm (FTA) circumference is a fundamental anthropometric measurement for determining the mesomorphic component in somatotype. This study examined the impact of contralateral limb opposition (+OP) on arm circumference measurement and ...

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy

Journal of Anatomy, EarlyView.
Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...

Cumulative effects of lifelong systemic excess growth hormone on postcranial skeletal morphology in adult mice

Journal of Anatomy, EarlyView.
Our μCT‐based pilot study reveals size and shape disparity in the adult postcranial skeleton of growth‐hormone model (bGH) mice relative to wild‐type mice. bGH mice have larger and more sexually dimorphic bones, with a systemic radiodensity increase in bony sesamoids and associated, but typically uncalcified, soft tissues.

Histological features of the structure of the long head of biceps brachii tendon in patients with concomitant injuries of the rotator cuff

Acta Biomedica Scientifica
Background. The long head of biceps brachii tendon plays an important role in shoulder pain. Surgical tactics remain controversial. There are two approaches: tenotomy of the long head of biceps brachii tendon and tenodesis.

Temporary transarticular stabilization with locking compression plate for the treatment of traumatic glenohumeral luxation in 10 dogs

Veterinary Surgery, EarlyView.
Abstract Objective The aim of this study was to describe the surgical technique, and the short to medium clinical outcome of dogs treated with temporary glenohumeral joint (GHJ) stabilization following traumatic luxation. Study Design Short case series.

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Galvanic vestibular stimulation reveals disruption of ipsilesional brainstem pathways in hemiparetic stroke survivors

Experimental Physiology, EarlyView.
Abstract The spatiotemporal structure of muscle coordination emerges from the collaboration and competition among cortical, brainstem and spinal pathways onto motor neuron pools, each continuously shaped by task demands, limb position and descending tract integrity.

Translational perspectives on neurophysiological responses and mechanisms in blood flow restriction exercise

Experimental Physiology, EarlyView.
Abstract Maintaining corticospinal tract function is crucial for voluntary movement. Exercise using high external loads/intensities is a promising intervention to promote adaptations to the corticospinal tract and improve physical function; however, such loads/intensities may not be tolerable or safe in populations with neurological disorders, motor ...
