Adaptations for bipedal walking: Musculoskeletal structure and three-dimensional joint mechanics of humans and bipedal chimpanzees (Pan troglodytes)

Autor: Matthew C. O’Neill, Brigitte Demes, Nathan E. Thompson, Susan G. Larson, Jack T. Stern, Brian R. Umberger

Humans are unique among apes and other primates in the musculoskeletal design of their lower back, pelvis and lower limbs. Here, we describe the three-dimensional ground reaction forces and lower/hind limb joint mechanics of human and bipedal chimpan

Three-dimensional kinematics of the pelvis and hind limbs in chimpanzee (Pan troglodytes) and human bipedal walking

Autor: Brian R. Umberger, Leng-Feng Lee, Nathan E. Thompson, Susan G. Larson, Brigitte Demes, Jack T. Stern, Matthew C O'Neill

Publikováno v: Journal of Human Evolution. 86:32-42

The common chimpanzee (Pan troglodytes) is a facultative biped and our closest living relative. As such, the musculoskeletal anatomies of their pelvis and hind limbs have long provided a comparative context for studies of human and fossil hominin loc

Electromyography of crural and pedal muscles in tufted capuchin monkeys (Sapajus apella): Implications for hallucal grasping behavior and first metatarsal morphology in euprimates

Autor: Biren A. Patel, Jack T. Stern, Susan G. Larson

Publikováno v: American Journal of Physical Anthropology. 156:553-564

A hypertrophied peroneal process of the hallucal metatarsal, as seen in prosimians, has been linked to a powerful hallucal grasp via the contraction of the peroneus longus (PL) muscle causing adduction of the big toe. Electromyography (EMG) studies o

Rotator cuff muscle function and its relation to scapular morphology in apes

Autor: Jack T. Stern, Susan G. Larson

Publikováno v: Journal of Human Evolution. 65:391-403

It is widely held that many differences among primate species in scapular morphology can be functionally related to differing demands on the shoulder associated with particular locomotor habits. This perspective is largely based on broad scale studie

Hallucal grasping in Nycticebus coucang: further implications for the functional significance of a large peroneal process

Autor: Doug M. Boyer, Susan G. Larson, Jack T. Stern, Amanda K. Kingston, Biren A. Patel

Publikováno v: Journal of Human Evolution. 58:33-42

Euprimate grasping feet are characterized by a suite of morphological traits, including an enlarged peroneal process on the base of the first metatarsal, which serves as the insertion site of the peroneus longus muscle. In prosimians, a large process

Distinct functional roles of primate grasping hands and feet during arboreal quadrupedal locomotion

Autor: Jack T. Stern, Michael C. Granatosky, Susan G. Larson, Ian J. Wallace, Biren A. Patel, Doug M. Boyer

Publikováno v: Journal of human evolution. 88

It has long been thought that quadrupedal primates successfully occupy arboreal environments, in part, by relying on their grasping feet to control balance and propulsion, which frees their hands to test unstable branches and forage. If this interlim

Telemetered electromyography of the supinators and pronators of the forearm in gibbons and chimpanzees: Implications for the fundamental positional adaptation of hominoids

Autor: Susan G. Larson, Jack T. Stern

Publikováno v: American Journal of Physical Anthropology. 115:253-268

Extant apes are similar to one another, and different from monkeys, in features granting them greater range of forearm rotation and greater size of the muscles that produce this motion. Although these traits may have been independently acquired by th
