Olivia Binfield
The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial s...
Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates? [0.03%]
Angela M Mossor,Jeremy Busken,Lorna Benden et al.
Angela M Mossor et al.
Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross-sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb b...
The first Pelagiceti whale from the Eocene of Poland with its evolutionary and biogeographic significance [0.03%]
Daniel Tyborowski,Svitozar Davydenko,Weronika Wierny et al.
Daniel Tyborowski et al.
The Eocene radiation of cetaceans marks the evolutionary transition of whales from amphibious ancestors to fully aquatic forms within the clade Pelagiceti. Here we report the first fossil record of an Eocene whale from Poland, represented b...
Segmental composition and nerve distribution of the brachial plexus in Galictis cuja [0.03%]
Galictis cuja副神经丛的节段性构成及其神经分布
Natan da Cruz de Carvalho,Thais Mattos Estruc,Ingrid Bete Palmeira et al.
Natan da Cruz de Carvalho et al.
Galictis cuja is a neotropical mustelid with terrestrial locomotor habits, yet the anatomy of its brachial plexus has remained undescribed. This study characterizes the origin, organization, and distribution of the brachial plexus nerves in...
Tracing the evolutionary history of the morpho-anatomy of baculum in primates [0.03%]
灵长类动物阴茎骨的形态解剖进化历史追溯
Federica Spani,Maria Pia Morigi,Matteo Bettuzzi et al.
Federica Spani et al.
Animal morphology reflects both evolutionary history and present-day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific v...
Clade-wide morphological and functional variation of the sauropsid columella [0.03%]
副爬行亚门柱骨的形态和功能变异
John Peacock,Serjoscha W Evers,Tiago R Simões et al.
John Peacock et al.
The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphol...
Oldest well-preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat) [0.03%]
印度（古吉拉特邦瓦斯坦褐煤矿）早始新世保存完好的最古老的真灵长类岩石骨座素化石

Mary T Silcox et al.
An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; ...
Vascular microforamina: A preliminary quantitative study on prevalence and cranial correlates in adult humans [0.03%]
人脑成人血管微孔的初步定量研究及其颅骨相关因素

Rafael Gallareto-Sande
Microforamina are small vascular channels connecting the cranial diploe to the endocranial space, hypothesized to play a role in thermoregulation and neuroimmune functions, yet their quantitative anatomy is poorly documented in humans and, ...
