Simple Summary Chimpanzees and humans are both species of hominoid primates that are closely related phylogenetically. One of the key differences between these two species is their use of their upper extremities. Humans use this limb mainly in manipulative tasks, while chimpanzees also use it during locomotion. In this study, we have analyzed the m...

Objectives: The objective of this study is to explore the anatomical differences in the insertion sites of the palmar radiocarpal ligaments between hylobatids and other hominoids that may be related to their different locomotor behaviors. Materials and Methods: The morphology of the insertion sites of the palmar radiocarpal ligaments was analyzed w...

Purpose: In the deltoid muscles of Pan troglodytes and Homo sapiens, we have analyzed the muscle architecture and the expression of the myosin heavy chain (MHC) isoforms. Our aim was to identify differences between the two species that could be related to their different uses of the upper limb. Research design: The deltoid muscle of six adult Pan t...

Objectives: In the present study, we have analyzed the anatomy of the radiocarpal joint ligaments and muscles in Pan troglodytes and Homo sapiens in order to identify similarities and differences between the two species that may be related to differences in hand use and function. Materials and Methods: Anatomical dissections of the ligaments and mu...

In the present study we calculated the muscle fascicle length (MFL) and the physiological cross-sectional area (PCSA) in the elbow flexor muscles of five Homo sapiens and five Pan troglodytes. We also assessed the expression of the myosin heavy chain (MyHC) isoforms with real-time quantitative polymerase chain reaction in the same muscles and, fina...

Purpose To identify anatomical differences in the deltoid tuberosity of Homo sapiens and Pan troglodytes, potentially relating to the different uses of the forelimb in these two phylogenetically related species. Basic procedures We have used three-dimensional geometric morphometrics (3D GM) to analyze the deltoid tuberosity of scanned humeri from...

Objectives: To identify anatomic differences in the insertion sites of the palmar radiocarpal ligaments in different species of hominoid primates that may be related to their different types of locomotion. Materials and methods: We have used three-dimensional geometric morphometrics (3D GM) to analyze the distal radius ligament insertion sites i...

The distal radius surface is formed by the facies articularis carpalis for the articulation of the lunate and scaphoid bones. The morphology of this articular surface is related to the different types of locomotion developed by hominoid primates. Our objective is to identify if the facies articularis carpalis acts as a modular unit or as independen...

The pectoralis minor is a shoulder muscle that acts in the retraction of the upper limb and the rotation and protraction of the scapula. These movements are very important for the different types of arboreal locomotion of hominoid primates. In order to better understand the variations of the pectoralis minor in humans, we have analyzed anatomic var...

Introduction: In this study, we analyze the carpal articular surface of the radius in humans and chimpanzees, which is divided into two surfaces for the articulation of the lunate and scaphoid bones (facies articularis carpalis). The morphology of this articular surface is related to the different types of locomotion developed by hominoid primates....

Introduction: The research analyzed the relative proportions of the pars clavicularis, pars acromialis and pars spinalis of the deltoid muscle in arboreal quadruped primates, semiterrestrial quadruped primates and vertical clinger primates. Our aim is to identify anatomical diferences of the deltoid muscle in vertical clinger primates that can be r...

Introduction: The pectoralis abdominis is a muscle derived from the pectoralis major that could be observed in different primate species. The literature indicate that pectoralis abdominis is absent as a separate muscle in chimpanzees and orangutans, it is inconstant in gibbons and it is constant in gorillas (also named pectoralis quartus). In goril...

The distal radius articular surface presents different funcional demands according to the diferent types of locomotion in hominoid primates, especially between biped humans and knuckle-walking chimpazees and gorillas. The analysis is based on the articular surface of the distal radius topography and geometric morphometric methods. The results, base...

The distal radius articular surface is one of the most important components of the wrist joint. This articular surface presents different functional demands according to the different types of locomotion in hominoid primates, specialy between biped humans and knuckle-walking chimpanzees and gorillas. In this study, a comparative morphological analy...
