It might seem strange that despite having a mass in his skull exercising pressure on the brain the patient feels no pain, but as anyone who has suffered a concussion can attest, pain is felt on the outside of the skull and not in the brain itself.

Its skull is frog-like, being broad with large eye sockets, but the fossil has features diverging from modern frogs.

There is evidence that trepanning ( or trephining ) — the practice of drilling holes in the skull — has been in widespread, if infrequent, use since 5000 BC.

The Skull and crossbones ( poison ) | skull and crossbones has long been a standard symbol for poison.

This narwhal skull has double tusk s, a rare trait in narwhals.

The sturdy nature of the animal's skull has ensured that many examples have been preserved as fossils, allowing variations between species and individuals to be studied.

In these cases, the stapes either is also missing or, in the absence of an eardrum, connects to the quadrate bone in the skull, although, it is presumed, it still has some ability to transmit vibrations to the inner ear.

The validity of the specimen has always been questioned .” Eventually, during the 1940s and 1950s, more advanced dating technologies, such as the fluorine absorption test, proved scientifically that this skull was actually a fraud.

Anapsid skull of Caretta caretta ( Loggerhead sea turtle ), a TestudineWhile " anapsid reptiles " or " anapsida " were traditionally spoken of as if they were a monophyletic group, it has been suggested that several groups of reptiles that had anapsid skulls may be only distantly related.

Several adaptations combine to protect the woodpecker's brain from the substantial pounding that the pecking behaviour causes: it has a relatively thick skull with relatively spongy bone to cushion the brain ; there is very little cerebrospinal fluid in its small subarachnoid space ; the bird contracts mandibular muscles just before impact, thus transmitting the impact past the brain and allowing its whole body to help absorb the shock ; its relatively small brain is less prone to concussion than other animals '.

He has a white, frequently skull-like face ( or actually has a skull for a face ) and speaks in a nasal voice.

The hard shell spreads an impact over a larger area, while the liner ( often polystyrene foam ) absorbs energy so less is transferred to the skull & brain.

Males tend to have slightly thicker and longer limbs and digit bones ( phalanges ), while females tend to have narrower rib cages, smaller teeth, less angular mandibles, less pronounced cranial features such as the brow ridges and external occipital protuberance ( the small bump at the back of the skull ), and the carrying angle of the forearm is more pronounced in females.

Bony fishes have additional dermal bone, forming a more or less coherent skull roof in lungfish and holost fish.

Magnetic fields are less distorted than electric fields by the skull and scalp, which results in a better spatial resolution of the MEG.

This procedure may be groundbreaking for patients with aneurysms near the skull base, as an approach through the nose is less invasive than traditional approaches.

This sometimes proves to provide a misdiagnosis of differential diagnoses including bilaterally symmetric schizencephaly ( a less destructive developmental process on the brain ), severe hydrocephalus ( cerebrospinal fluid excess within the skull ), and alobar holoprosencephaly ( a neurological developmental anomaly ).

Its skull resembles that of polecats in its size, massiveness and the development of its ridges and depressions, though it is distinguished by the extreme degree of constriction behind the orbits where the width of the cranium is much less than that of the muzzle.

It also provides a space of approximately 30 mm ( 1. 2 inch ) between the helmet's shell and the wearer's head so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull.

Compared to minks and other weasels — also fellow members of the genus Mustela — the polecat has a shorter, more compact body a more powerfully built skull and dentition, and is less agile.

The European polecat is, however, not as maximally adapted in the direction of carnivory as the steppe polecat, being less specialised in skull structure and dentition.

Jawless fish and sharks only possess a cartilaginous endocranium, with the upper and lower jaws being separate elements. Bony fishes have additional dermal bone, forming a more or less coherent skull roof in lungfish and holost fish.

The body length is not less than, condylobasal length of skull, zygomatic width, and length of upper carnassial tooth over long.

It is the smallest of the true hyenas and retains many primitive viverrid characteristics lost in larger species, having a smaller and less specialised skull.

The skull of the striped hyena differs from that of the brown and spotted hyena by its smaller size and slightly less massive build.

Alternatively the " klappvisor " was employed on bascinets ; this type of visor tended to project less strongly from the face and was hinged at a single point in the centre of the brow of the helmet skull.

From around 1400 both the skull of the helmet and the hinged visor became less angular and more rounded over time, with almost globular forms becoming common from c. 1435.

The skull generally resembles that of Camelus, the relatively larger brain-cavity and orbits and less developed cranial ridges being due to its smaller size.
