Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

An investigation by LA-ICP-MS of possum tooth enamel as a model for identifying childhood geographical locations of historical and archaeological human from New Zealand [PDF]

open access: yes, 2012
LA -IC P-MS (laser ablation-inductively coupled plasma-mass spectrometry) has been used to analyse enamel from the teeth of brushtail possum (Trichosurus vulpecula) in order to model a method for identifying the childhood geographical origin of human ...

Genome-wide DNA methylation profile of developing deciduous tooth germ in miniature pigs

open access: yesBMC Genomics, 2016
DNA methylation is an important epigenetic modification critical to the regulation of gene expression during development. To date, little is known about the role of DNA methylation in tooth development in large animal models.

Exploring developmental changes in femoral midneck cross‐sectional properties

open access: yesThe Anatomical Record, EarlyView.
The properties of femoral midneck cross‐sections exhibit a unique growth pattern that is characterized by shape changes during adolescence. Abstract This research delves deeper into previous works on femoral cross‐sectional properties during ontogeny by focusing for the first time on the human femoral midneck. The ontogenetic pattern of cross‐sectional

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

open access: yesThe Anatomical Record, EarlyView.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

The prevalence of impacted permanent maxillary canines in Maltese school children : a pilot study [PDF]

open access: yes, 1995
The aetiology of ectopic canines is not clear. A number of causes have been put forward such as the long path of eruption of the maxillary canine, lack of guidance by the lateral incisor root, narrow arches, cystic enlargement of the dental follicle ...

Shaping the human face: Periosteal bone modeling across ontogeny

open access: yesThe 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.
