Muscle morphology and intramuscular fat after treatment‐as‐usual including botulinum neurotoxin A injections in children with cerebral palsy

Developmental Medicine &Child Neurology, EarlyView.
Normalized muscle volume remained unchanged in all evaluated muscles after the 12‐month treatment‐as‐usual in children with cerebral palsy. Higher intramuscular fat fraction was observed in the medial gastrocnemius, suggesting concurrent intramuscular fat infiltration.

Functional compartmentalization of the anconeus: A three‐dimensional study of muscle morphology and innervation patterns

Journal of Anatomy, EarlyView.
In this anatomic study of anconeus utilizing dissection, digitization and 3D modeling, anconeus was found to have three distinct parts: proximal, distal, and deep. Each part had unique morphology, architecture and innervation, indicating different roles in forearm pronation, elbow extension, and joint stabilization.

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 ...
