SKULL - LoveToKnow Article on SKULL

The pro-, epi- and opisth-otic bones are all developed, but the epiotic usually fuses with the supra-occipital and the opisthotic with the exoccipital.
From what has been seen of the skull bones in the above necessarily concentrated and abridged account, it is obvious that they do not correspond to the traces of segmentation as indicated by the cranial nerves, and for this and other reasons the vertebrate theory of the skull is no longer believed in.
The periotki capsule blends with the squarnosal and tympanic to form the petrous bone, though it is practically only in man that the second visceral arch ossifies on to this as a styloid process.

II. Osteology. 5c. The Exterior of the Skull. Gray, Henry. 1918. Anatomy of the Human Body.

The surface is traversed by three sutures, viz.: (1) the coronal sutures, nearly transverse is direction, between the frontal and parietals; (2) the sagittal sutures, medially placed, between the parietalb> bones, and deeply serrated in its anterior two-thirds; and (3) the upper part of the lambdoidal suture, between the parietals and the occipital.
The squamosal suture arches backward from the pterion and connects the temporal squama with the lower border of the parietalb>: this suture is continuous behind with the short, nearly horizontal parietomastoid suture, which unites the mastoid process of the temporal with the region of the mastoid angle of the parietalb>.
The skull is often somewhat flattened in the neighborhood of the parietalb> foramina, and the term obelion is applied to that point of the sagittal suture which is on a level with the foramina.

The axial skeleton Chapter 7

The styloid process, near the base of the mastoid process, is attached to ligaments that support the hyoid bone and to the tendons of several muscles associated with the hyoid bone, the tongue, and the pharynx.
Articulations: The paired nasal bones articulate with one another and with the frontal, ethmoid, and maxillary bones (Figures 7-3c,d, and 7-4a).
A specialized joint between the occipital bone and the first vertebra of the neck stabilizes the positions of the brain and spinal cord while permitting a considerable range of head movements.

The Harper Fragment

In contrast, occipital bone is characterized by major variations on its internal surface (i.e., many different bumps and grooves from various things), much greater curvature, and substantial variation in thickness (compare drawings of internal aspects of parietalb> and occipital bone in Figure 2).
More importantly, the origin of the Harper fragment as parietalb> bone does not in any way support the conclusion that John Kennedy was struck in the head by one and only one bullet.
In contrast to parietalb> bone, occipital bone does not show a pattern of vascular grooving.

dermal bone, a bone developed by ossification in the skin.

Head Lecture notes

The spine of the sphenoid bone lies medial to the mandibular fossa.
The paired nasal bones articulate with the frontal bone and frontal processes of the maxillary bones (Clemente plate 522 fig.
The flat bones of the skull are also pierced by emissary foramina transmitting emissary veins connecting veins of the scalp with the dural venous sinuses inside the skull (this is a possible route for the spread of infection).

In addition to these bones, the parietalb> bones also fuse to the sphenoid bones.
The frontal bone is fused with the parietalb> bones (coronal suture), the sphenoid bones, maxilla and nasal bones.
Cranium: The nine (9) bones that make up the cranium are: the frontal bone (1), the paired parietalb> bones (2), the paired temporal bones (2), the paired ethmoid bone (1), the paired sphenoid bone (2) and the occipital bone (1).

eMedicine - Temporal Bone, Fractures : Article by Richard Woodcock, MD

Pathophysiology: Longitudinal fractures typically result from trauma to the temporal or parietalb> region, and fractures of the temporal squamosa or parietalb> bone are common.
Intervention: No specific intervention techniques are currently available for therapy for temporal bone fracture per se.
While temporal bone fracture is not a typical injury in this setting, investigate further any injury not explained by appropriate history.

Parietalb> bone - Wikipedia, the free encyclopedia

The parietalb> bones ( os parietale) are bones in the human
The parietalb> bone is ossified in membrane from a single center, which appears at the parietalb> eminence about the eighth week of fetal life.
The mastoid angle is truncated; it articulates with the occipital bone and with the mastoid portion of the temporal, and presents on its inner surface a broad, shallow groove which lodges part of the transverse sinus.

parietalb> lobe: Definition and Much More From Answers.com

The division of each hemisphere of the brain that lies beneath each parietalb> bone.
The central sulcus separates the parietalb> lobe from the frontal lobe, and the parieto-occipital sulcus separates the parietalb> and occipital lobe.
The parietalb> lobe plays important roles in integrating sensory information from various senses, and in the manipulation of objects.

Neck

The skull is one of the principle groups of bones in the human anatomy.
The U-shaped hyoid bone is found in the neck, and is attached by ligaments to the temporal bones.
In the newborn, these sutures are not yet developed, with the bones being attached by cartilage which ossifies over time as the bones of the skull fuse together.

Bone, Parietalb> - Talk Medical

Although the parietalb> bone is curved, it is considered a flat bone (as opposed to a tubular bone).
The parietalb> bone is shaped like an irregular quadrangle.
It articulates (joins) with the other parietalb> bone in the midline (top of the head), with the frontal bone in front of it, with the occipital bone behind it, and with the sphenoid and temporal bones lower down on the side of the skull.

http://www.talkmedical.com/medical-dictionary/2003/Bone-Parietal



Parietalb> Bone

One "parietalb> bone" is located on each side of the skull just behind the frontal bone.
Together, the parietalb> bones form the bulging sides and roof of the cranium.
They are fused in the middle along the "sagittal suture," and they meet the frontal bone along the "coronal suture." Where the two sutures meet is called the "bregma." There is a gap through the parietalb> bone that serves as a passageway for blood vessels and nerves, called the "parietalb> foramen."
