"We found a clear relationship between the frontal bones and forebrain and the parietal bones and midbrain," Bhullar said.
The anterior fontanelle enables the two frontal bones of the skull to slide past each other, much like the tectonic plates that make up the Earth's crust.
Many snake species also have a hinge on the roof of the skull between the nasal and frontal bones that allows the snout to be raised slightly.
The second PC axis was defined by differences relating to the angle between the nasal and frontal bones as well as the broadness of the skull.
Buffaloes have extensive sinuses and frontal bones, meaning that the penetrating captive bolt devices recommended for cattle may prove ineffective in reliably inducing unconsciousness.
The opening gets gradually smaller as new bone is laid down, and is completely closed by about two years of age, at which time the frontal bones have fused to form a structure called the metopic suture.
What sets the Bovidae apart from other cud-chewing artiodactyls (notably deer, family Cervidae) is the presence of horns consisting of a sheath covering a bony core that grows from the skull's frontal bones.
Pain thresholds were assessed over: the frontal bones, C5-C6 zygapophyseal joints and second metacarpals (PPT); the dorsal aspect of the hand (HPT and CPT); and the tibialis anterior (TA) muscles.
The majority of deer have antlers, defined as solid, bony, branched outgrowths of the frontal bones, present only in the males (but also in female reindeer) and shed seasonally.
He wears his black hair parted in the middle and rather long; the prominence of the frontal bones just above his eyebrows and the smallness of his mustache, mouth, and chin give him a strange, old-young look, boyish and yet wise, weak and yet fiery.
Long panels of openwork carving showing human figures, animals, and abstract designs were carried in one initiation dance, while the frontal bones of human skulls, which had been over-modeled, painted, and embellished with hair and beards, were worn as masks in other dances.
