The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

open access: yes, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.

Information decomposition of multichannel EMG to map functional interactions in the distributed motor system [PDF]

open access: yes, 2019
The central nervous system needs to coordinate multiple muscles during postural control. Functional coordination is established through the neural circuitry that interconnects different muscles.

In Vivo Time- Resolved Microtomography Reveals the Mechanics of the Blowfly Flight Motor [PDF]

open access: yes, 2014
Dipteran flies are amongst the smallest and most agile of flying animals. Their wings are driven indirectly by large power muscles, which cause cyclical deformations of the thorax that are amplified through the intricate wing hinge.

Functional characterization of orbicularis oculi and extraocular muscles [PDF]

open access: yes, 2016
The orbicularis oculi are the sphincter muscles of the eyelids and are involved in modulating facial expression. They differ from both limb and extraocular muscles (EOMs) in their histology and biochemistry. Weakness of the orbicularis oculi muscles is a

The scaling of postcranial muscles in cats (Felidae) I: forelimb, cervical, and thoracic muscles [PDF]

open access: yes, 2016
The body masses of cats (Mammalia, Carnivora, Felidae) span a ~300‐fold range from the smallest to largest species. Despite this range, felid musculoskeletal anatomy remains remarkably conservative, including the maintenance of a crouched limb posture at

Fatigue and Recovery from Dynamic Contractions in Men and Women Differ for Arm and Leg Muscles [PDF]

open access: yes, 2013
Introduction: Whether there is a gender difference in fatigue and recovery from maximal velocity fatiguing contractions and across muscles is not understood.

Mapping the cortical representation of the lumbar paravertebral muscles [PDF]

open access: yes, 2007
Objective: The aim of this study was to map the cortical representation of the lumbar spine paravertebral (LP) muscles in healthy subjects. Methods: Transcranial magnetic stimulation (TMS) was employed to map the cortical representations of the LP ...

The Energy Benefits of the Pantograph Wing Mechanism in Flapping Flight: Case Study of a Gull [PDF]

open access: yes, 2015
Bird wings generally contain a 4-bar pantograph mechanism in the forearm that enables the wrist joint to be actuated from the elbow joint thus reducing the number of wing muscles and hence reducing the wing inertia and inertial drag.

An autopsy study of a familial oculopharyngeal muscular dystrophy (OPMD) with distal spread and neurogenic involvement [PDF]

open access: yes, 1981
An 81-year-old man from a family with a history of oculopharyngeal muscular dystrophy (OPMD) involving 6 members over 4 generations is described. The patient first noted drooping of his eyelids at the age of 65.

Musculoskeletal modelling of an ostrich (Struthio camelus) pelvic limb: influence of limb orientation on muscular capacity during locomotion [PDF]

open access: yes, 2015
We developed a three-dimensional, biomechanical computer model of the 36 major pelvic limb muscle groups in an ostrich (Struthio camelus) to investigate muscle function in this, the largest of extant birds and model organism for many studies of locomotor
