The microscopic anatomy of endothelial cells in human atherosclerosis: Focus on ER and mitochondria

Dilation of ER is a common ultrastructural feature found in the ECs of human atherosclerotic plaque. Adjacent mitochondria also show alterations in their structural organization. Abstract Once regarded merely as a bland lipid storage disease consequence of aging, atherosclerosis is currently considered a slow and continuous inflammatory process...

Comment on ‘Krapina atlases suggest a high prevalence of anatomical variations in the first cervical vertebra of Neanderthals’

A review of the observation of an anterior cleft on the atlas of a Neanderthal from Krapina.

Petrosal and bony labyrinth morphology of the stem paenungulate mammal (Paenungulatomorpha) Ocepeia daouiensis from the Paleocene of Morocco

We provide the first detailed description of the petrosal and labyrinth of the stem paenungulate mammal Ocepeia (Paleocene of Morocco). It shows a few derived features such as a small labyrinth and a large pars mastoidea, beside a primitive morphology as for the whole skull of Ocepeia . Together with the generalized skull pattern also seen in the earliest...

Anatomy and ontogenetic changes of the facial and gular musculature of the tetra Astyanax brucutu: A remarkable case of adaptation to durophagy

Astyanax brucutu is a peculiar durophagous Neotropical tetra that exhibits a dramatic ontogenetic shift in its diet, which is coupled with by equally remarkable musculoskeletal changes in its feeding apparatus. Myological changes primarily involve expansions of specific portions of the adductor mandibulae and associated tendons and ligaments that...

Is relative growth by the mammalian heart biphasic or monophasic?

Relative growth by the heart of Horro sheep has been reported to be biphasic and discontinuous on the logarithmic scale, with a substantial increase in both relative and absolute mass of the heart occurring shortly after birth. However, the discontinuity was an artifact of logarithmic transformation. Both the logarithmic distribution and the arithmetic...

Monitoring muscle over three orders of magnitude: Widespread positive allometry among locomotor and body support musculature in the pectoral girdle of varanid lizards (Varanidae)

Abstract There is a functional trade‐off in the design of skeletal muscle. Muscle strength depends on the number of muscle fibers in parallel, while shortening velocity and operational distance depend on fascicle length, leading to a trade‐off between the maximum force a muscle can produce and its ability to change length and contract rapidly. This...

Pentadactyl manus of the Metoposaurus krasiejowensis from the Late Triassic of Poland, the first record of pentadactyly among Temnospondyli

Metoposaurus krasiejowensis from the Late Triassic of Poland shows a unique for Temnospondyli structure of the manus with five digits. Based on the distribution of pentadactyly vs. tetradactyly in the temnospondyl manus, the number of digits was not phylogenetically constrained in temnospondyls, similar to today's amphibians. Abstract Temnospondyli...

Three‐dimensional structure of seminiferous tubules in the Syrian hamster

The present study revealed the 3D structure of seminiferous tubules in developing and adult Syrian hamsters, which is different from that in mice and rats. Abstract The hamster is useful for the study of male reproductive biology. However, unlike in the mouse and rat, the gross structure of seminiferous tubules in the hamster is largely unknown....

Producing 3D printed high‐fidelity retroperitoneal models from in vivo patient data: The Oxford Method

We outline the steps required to produce a high fidelity anatomical model from in vivo patient data, followed by a discussion of the advantages and disadvantages relative to current available options. Abstract Macroscopic anatomy has traditionally been taught using cadaveric material, lectures and a variable amount of additional resources such as...

Left/right difference in the course and division of the pulmonary arterial branches in the lung upper lobe: A study using human embryos and early fetuses

This study describes observations of histological sections from serial sagittal sections of 25 embryos and fetuses at 6–7 weeks of gestation and demonstrating how left/right differences in a configuration of the pulmonary artery and its branches establishes. Abstract Although left/right differences in a configuration of the pulmonary artery (PA)...
