Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

The role of urothelium in induced ossification in skeletal muscle

open access: yes, 2006
It is a well established phenomenon that the epithelial lining of the urinary bladder (urothelium) when implanted into skeletal muscle induces ectopic ossification. However, despite numerous observations, this reaction is poorly understood.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Palovarotene inhibits heterotopic ossification and maintains limb mobility and growth in mice with the human ACVR1R206H Fibrodysplasia Ossificans Progressiva (FOP) mutation

open access: yesJournal of Bone and Mineral Research, 2016
Fibrodysplasia ossificans progressiva (FOP), a rare and as yet untreatable genetic disorder of progressive extraskeletal ossification, is the most disabling form of heterotopic ossification (HO) in humans and causes skeletal deformities, movement ...

Influence of Functional Disturbance Osteo (chondro) clasts in Endochondral Ossification

open access: yes, 2006
P(論文)Endochondral ossification is preceded by the vascular invasion into hypertrophic chondrocyte lacunae. Although it has been described that the osteoclasts or chondroclasts are primarily responsible for the breakdown of the transverse septa facing the

Heterotopic Ossification; Case Report

open access: yes, 2011
Heterotrophic ossification is the development of bone in abnormal areas like muscle tissue. Neurogenic, traumatic and congenital are just a few of the causes which vary a lot.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

The importance of markers of osteolysis and osteogenesis in the pathogenesis of cephalohematoma in newborns

open access: yesActa Biomedica Scientifica
Background. Of particular importance in the repair process for cephalohematomas is the pathological remodeling of the bones of the cranial vault. Local changes in the bones of the skull are accompanied by the processes of osteolysis and osteogenesis and ...

Ossification of bony nerve canals in the human head: a comparison between the endochondral and membranous bones

open access: yes
Cranial nerves and their branches pass through bony canals in the head. To reveal an ossification manner for closing the nerve canal, we examined histological sections from 32 human fetus heads at 9–18 and 28–40 weeks.

Isolated ligamentum flavum ossification in primary hypoparathyroidism

open access: yes, 2018
Basckground: The ligamenta flava can undergo ossification and calcification resulting in myelopathy. Only seven cases of ligamentumflavum ossification in association with hypoparathyroidism have been reported, most of which had concurrent osseous changes
