Exploring the biomechanics of taurodontism
Journal of Anatomy - Tập 226 Số 2 - Trang 180-188 - 2015
AbstractTaurodontism (i.e. enlarged pulp chamber with concomitant apical
displacement of the root bi/trifurcation) is considered a dental anomaly with
relatively low incidence in contemporary societies, but it represents a typical
trait frequently found in Neandertal teeth. Four hypotheses can be envisioned to
explain the high frequency in Neandertals: adaptation to a specific occlusal
loading reg...
Using occlusal wear information and finite element analysis to investigate stress distributions in human molars

The anatomy of language: contributions from functional neuroimaging
Journal of Anatomy - Tập 197 Số 3 - Trang 335-359 - 2000
This article illustrates how functional neuroimaging can be used to test the
validity of neurological and cognitive models of language. Three models of
language are described: the 19th Century neurological model which describes both
the anatomy and cognitive components of auditory and visual word processing, and
2 20th Century cognitive models that are not constrained by anatomy but
emphasise 2 di...
Muscle fibre size and type distribution in thoracic and lumbar regions of erector spinae in healthy subjects without low back pain: normal values and sex differences
Journal of Anatomy - Tập 190 Số 4 - Trang 505-513 - 1997
This study sought to investigate the normal muscle fibre size and type
distribution of the human erector spinae, both in thoracic and lumbar regions,
in a group of 31 young healthy male (n=17) and female (n=14) volunteers. Two
percutaneous muscle biopsy samples were obtained under local anaesthesia, from
the belly of the left erector spinae, at the levels of the 10th thoracic and 3rd
lumbar verteb...
Feasibility, accuracy and safety of a percutaneous fine‐needle biopsy technique to obtain qualitative muscle samples of the lumbar multifidus and erector spinae muscle in persons with low back pain
Journal of Anatomy - Tập 233 Số 4 - Trang 542-551 - 2018
AbstractThe lumbar muscular system, in particular the lumbar multifidus muscle
(LM) and the erector spinae muscle (ES), plays an important role in stabilizing
and mobilizing the lumbar spine. Based on the topography, the lumbar paraspinal
muscles can be classified into local and global muscles. LM is part of the local
system, whereas ES is part of the global system. Therefore, it is interesting to...
Intramuscular architecture of the autochthonous back muscles in humans
Journal of Anatomy - Tập 222 Số 2 - Trang 214-222 - 2013
AbstractMany training concepts take muscle properties such as contraction speed
or muscle topography into account to achieve an optimal training outcome. Thus
far, the internal architecture of muscles has largely been neglected, although
it is well known that parameters such as pennation angles or the lengths of
fascicles but also the proportions of fleshy and tendinous fascicle parts have a
major...
The core planar cell polarity gene, Vangl2, maintains apical‐basal organisation of the corneal epithelium
Journal of Anatomy - Tập 234 Số 1 - Trang 106-119 - 2019
AbstractThe role of the core planar cell polarity (PCP) pathway protein, Vangl2,
was investigated in the corneal epithelium of the mammalian eye, a paradigm
anatomical model of planar cell migration. The gene was conditionally knocked
out in vivo and knocked down by siRNA, followed by immunohistochemical,
behavioural and morphological analysis of corneal epithelial cells. The primary
defects obser...
Functional anatomy of the forelimb in Promegantereon* ogygia (Felidae, Machairodontinae, Smilodontini) from the Late Miocene of Spain and the origins of the sabre‐toothed felid model
Journal of Anatomy - Tập 216 Số 3 - Trang 381-396 - 2010
AbstractWe examine the functional anatomy of the forelimb in the primitive
sabre‐toothed cat Promegantereon ogygia in comparison with that of the extant
pantherins, other felids and canids. The study reveals that this early
machairodontine had already developed strong forelimbs and a short and robust
thumb, a combination that probably allowed P. ogygia to exert relatively greater
forces than extan...
Absence of large‐diameter sensory fibres in a nerve to the cat humerus
Journal of Anatomy - Tập 208 Số 2 - Trang 251-255 - 2006
AbstractA fine branch of the median nerve innervates the periosteum and
medullary cavity of the cat humerus. After branching to innervate the periosteum
on the medial surface of the humerus, the nerve enters and supplies the
medullary cavity via a nutrient foramen, accompanied by a small artery and vein.
The composition of the fibres in the nerve was examined using electron
microscopy. Myelinated ...
Evolution of the amygdaloid complex in vertebrates, with special reference to the anamnio‐amniotic transition
Journal of Anatomy - Tập 211 Số 2 - Trang 151-163 - 2007
AbstractNumerous studies over the last few years have demonstrated that the
amygdaloid complex in amniotes shares basic developmental, hodological and
neurochemical features. Furthermore, homologous territories of all the main
amygdaloid subdivisions have been recognized among amniotes, primarily
highlighted by the common expression patterns for numerous developmental genes.
Thus, derivatives from...
