What's the difference between pericranium and skull?
Pericranium
Definition:
(n.) The periosteum which covers the cranium externally; the region around the cranium.
Example Sentences:

(4) Complications such as adherence of the dermis to the underlying pericranium, lack of motion in a portion of or the entire forehead, hyperactivity around areas of immobility, muscle irregularities, and also surgically produced depressions which require grafting, skin sloughing, permanent nerve injury, persistent sensory nerve loss, and short-term improvement have been avoided by paying attention to diagnosis, surgical planning, and technique, and postoperative care.

(11) The pericranium was used for augmentations, coatings, and suspensions, with the latter two proving to be the most useful.
(12) Separate and independently vascularized layers of this region include hair-bearing scalp, glabrous skin, tempororoparietal fascia (and galea aponeurotica), temporalis muscle and fascia, and pericranium.
(13) Three to four (or more) stitches are inserted between the galea and the pericranium or between the pericranium and the craniotomy flap at the end of the surgical procedure.
(14) A CT scan showed its origin to be from the pericranium and demonstrated its intracranial extension.
(15) Like other autogenous grafts, the pericranium may eventually undergo some resorption; however, with experience, overcorrection can be planned.
(16) Underlying the temporalis muscle, the pericranium was thinner and more adherent than elsewhere with no subpericranial tissue.
(17) The bone matrix proteins investigated (62 kDa, bone sialoprotein I and II, and osteopontin) appeared early, adjacent to the periosteal surfaces (pericranium and dura mater) and the marginal bone.
(18) Preservation of vascularized anterior pericranium is credited with reduction of the chances of anterior table bone resorption and subsequent cosmetic deformity.
(19) The histologic sections reveal that no alkaline phosphatase activity could be observed within the coronal suture as well as the dura mater, while the pericranium did contain this enzyme.
(20) Of the 31 cases, 15 had dural lacerations with 4 of these requiring patching with pericranium.
Skull
Definition:
(n.) A school, company, or shoal.
(n.) The skeleton of the head of a vertebrate animal, including the brain case, or cranium, and the bones and cartilages of the face and mouth. See Illusts. of Carnivora, of Facial angles under Facial, and of Skeleton, in Appendix.
(n.) The head or brain; the seat of intelligence; mind.
(n.) A covering for the head; a skullcap.
(n.) A sort of oar. See Scull.
Example Sentences:
(1) However, CT will be insensitive in the detection of the more cephalic proximal lesions, especially those in the brain stem, basal cisterns, and skull base.
(2) For the case described by the author primary tearing of the chiasma due to sudden applanation of the skull in the frontal region with burstfractures in the anterior cranial fossa is assumed.
(3) The skull films and CT scans of 1383 patients with acute head injury transferred to a regional neurosurgical unit were reviewed.
(4) We report a rare case of odontogenic abscess, detected while the patient was in the intensive care unit (ICU), which resulted in sepsis and the patient's death due to mediastinitis, skull osteomyelitis, and deep neck cellulitis.
(5) This lack of symmetry in shape and magnitude may be due to non-sphericity of the skull over the temporal region or to variations in conductivities of intervening tissues.
(6) As I looked further, I saw that there was blood and hair and what looked like brain tissue intermingled with that to the right area of her skull."
(7) The inner table of the skull over the lesion was eroded.
(8) A three-dimensional anatomic model of a human skull was produced with birefringent materials for photoelastic analysis.
(9) The effects on skull growth of plating the coronal suture and frontal bone were studied in New Zealand White rabbits.
(10) Much more recently, use of modern CT ("computed tomography") scanning equipment on the London Archaeopteryx's skull has enabled scientists to reconstruct the whole of its bony brain case - and so model the structure of the brain itself.
(11) Tension pneumocephalus was diagnosed by computed tomography (CT) scan and plain skull X-ray.
(12) After removal from the skull, the brains were processed for histopathological evaluation of ischemic neuronal damage by light microscopy and morphometry.
(13) The author describes three systems for (1) the treatment of mandibular fractures; (2) the treatment of midface fractures, for reconstructive surgery of the facial skeleton and the skull, and for orthognathic surgery; and (3) the reconstruction of mandibular defects including condyle replacement.
(14) To avoid the complications attributable to the cervical spine, we recommend roentgenographic examination in all neurofibromatosis patients who are about to have general anesthesia or skull traction for treatment of scoliosis.
(15) Eight macerated human child skulls with a dental age of approximately 9.5 years (mixed dentition) were consecutively subjected to an experimental standardized high-pull headgear traction system attached to the maxilla at the first permanent molar area via an immovable acrylic resin splint covering all teeth.
(16) Lateral skull X-ray images are routinely used in cephalometric analysis to provide quantitative measurements useful to clinical orthodontists.
(17) The absence of a visible fracture on plain skull radiographs does not exclude a fracture, and those patients with clinical signs of a fracture should be treated appropriately and further investigations performed.
