Anatomical reorganization within the hand and forelimb of <it>Perodicticus potto</it>

Boettcher, M., Dickinson, E., Leonard, K., Herrel, A., & Hartstone-Rose, A. (2020, April). FASEB JOURNAL, Vol. 34.

By: M. Boettcher*, E. Dickinson n, K. Leonard n, A. Herrel * & A. Hartstone-Rose n 

TL;DR: Despite reports of the potto’s high grip strength, the findings demonstrate relatively below‐average force capacity (relatively low physiological cross‐sectional area) within the digital flexors of this species, which suggests that the gripping ability ofThis species may be less extraordinary than previously hypothesized.

Intraspecific and intrafamilial variation in primate forearm muscle architecture

Hartstone-Rose, A., Boettcher, M., Seelye, J., Worden, N., & Dickinson, E. (2020, April). FASEB JOURNAL, Vol. 34.

By: A. Hartstone-Rose n , M. Boettcher*, J. Seelye n, N. Worden n & E. Dickinson n

TL;DR: Assessing both qualitative (presence/absence of specific muscles) and quantitative (physiological cross‐sectional area, fascicle length and muscle mass) differences in forearm muscle architecture of larger intraspecific and samples with greater coverage of specific primate families than had been included in previous work found that there is great variation in both the extent of separation and fusion of flexor digitorum superficialis and profundus in most species of callitrichids and Saimiri.
