Clin Sports Med 2021 Apr 10;40(2):409-428. Epub 2021 Feb 10.

Atlanta Braves, Truist Park, 755 Battery Avenue, Southeast, Atlanta, GA 30339, USA.

The athlete's hip is complex when it comes to the surrounding musculature-approximately 21 different muscles can cross the hip and pelvis region, all synchronously working to maintain pelvic stability and functional hip activities. Commonly injured muscle groups for high-level athletes include flexors, adductors, abductors, and/or proximal hamstring musculotendinous complex. These muscle groups work in harmony; however, each has an independent function and propensity for injury. Read More

An CRE Knock-In Mouse Labels Motor Neurons Involved in Fine Motor Control.

eNeuro 2021 Jan-Feb;8(1). Epub 2021 Feb 1.

Department of Neuroscience, University of Texas Southwestern Medical Center, Dallas, TX 75390

Motor neurons (MNs) innervating the digit muscles of the intrinsic hand (IH) and intrinsic foot (IF) control fine motor movements. The ability to reproducibly label specifically IH and IF MNs in mice would be a beneficial tool for studies focused on fine motor control. To this end, we find that a CRE knock-in mouse line of , a developmentally expressed basic helix-loop-helix (bHLH) transcription factor, reliably expresses CRE-dependent reporter genes in ∼60% of the IH and IF MNs.

Functional morphology of the jaw adductor muscles in the Canidae.

Anat Rec (Hoboken) 2020 11 25;303(11):2878-2903. Epub 2020 Mar 25.

Department of Musculoskeletal Biology, Institute of Ageing and Chronic Disease, Ringgold Standard Institution, University of Liverpool, Liverpool, UK.

Cranial form is closely allied to diet and feeding behavior in the Canidae, with the force and velocity of jaw-closing depending on the bony morphology of the skull and mandible, and the mass, architecture, and siting of the jaw adductor muscles. Previously, little has been reported on the details of the form and function of canid jaw adductor muscles, with earlier studies basing functional hypotheses on data derived from dry skull specimens. Here we use empirically derived muscle data from fresh-frozen specimens to explore the architecture of the muscles, and to inform finite element analyses models that predict bite force and strain energy in 12 species of wild canid.
