Shaping the human face: Periosteal bone modeling across ontogeny

The Anatomical Record, EarlyView.
Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

The Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

Mineralized area of the human rib cross‐sections from early puberty until adulthood

The Anatomical Record, EarlyView.
Abstract Ribs undergo numerous changes during growth and development. Although they occur both externally and internally, the latter are not as extensively documented during the transition from puberty to adulthood. Therefore, it is unknown how rib cross‐sectional mineralized area changes during this period.

A proximodistal gradient in bone structure and mechanics in the wings of Seba's short‐tailed bat, Carollia perspicillata

The Anatomical Record, EarlyView.
Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Bone mineral density and bone mineral content among female elite athletes

Bone, 2019
Exercise is a protective factor for the appearance of osteoporosis, but not all physical activities have the same effect on bones. Low-impact sports, like swimming, may a have a negative or no effect. The aim of the present study is to evaluate bone mineral density (BMD, g/cm2) and bone mineral content (BMC, kg) among female high performance athletes ...

BONE MINERAL CONTENT IN CHILDREN WITH FRACTURES

Journal of Pediatric Orthopaedics, 1983
Bone mineral content was measured in the forearms of 90 children who had recent fractures. The data were compared with those of age-matched healthy children. Bone mineral content was significantly reduced in children in whom fractures were caused by low-energy trauma.
