Their incidence varies among different populations and they constitute an anthropo- logical marker. Precise mechanism of formation is unknown and being under the control of genetic background and environmental factors. The aim of the current study is to investigate the incidence of WBs presence, number and topographical distribution according to gender and side in Greek adult dry skulls. Materials and methods: All sutures and fontanelles of 166 Greek adult dry skulls were examined for the presence, topography and number of WBs. One hundred and nineteen intact and 47 horizontally craniotomised skulls were examined for WBs presence on either side of the cranium, both exocranially and intracranially. Results: One hundred and twenty-four (74.7%) skulls had WBs.

    VARIATIONS In The Ossification Of The Human Skull By J. V. REES-ROBERTS. M.B. C.M., B.Sc., (Edin.)j D.P.H., (Camb.)» 0 TABLE OP CONTENTS Vol. I.

I made observations on 15 points of variation in a series of 613 crania, representative of civilised and exotic races. Whilst making my observations on these points I noticed additional variations which had not previous -ly been described:- (1) Meningeal grooves on the external surface of the skull. (2) Median condylar foramen. (3) Boat-shaped palate. (4) Indications of the separation of the tabular portion of the occipital from the ex-occipitals in the adult j skull. (5) The skull of Kempff a German gave me the idea of the frontal grooves, but the priority of discovery and publi¬ cation belong to Professor Dixon of C ardiff. The variations found in the human skull are replete with interest, affording as they do in some instances remarkable conformity to structures which in lower forms of life are found to be normally present. I have at every step availed myself of the informa¬ tion obtained from the study of Comparative Anatomy. A general review of my investigation seems to point out that many of these variations are not so ii I so characteristically "simian" as had hitherto been supposed.

  • Bekah's Normal Labor Assignment #7
    1 1. How many different elements, or “parts”, are there to the fetal skull? There are 51 bony elements of the fetal skull. These elements are separated by either cartilage or connective tissue as the newborn skull is only partially ossified at the time of birth. 2. What are sutures? What are fontanels? Sutures: In the newborn skull, there are gaps between the edges of membranous bones. These gaps, which are spanned by a flexible bridge of membranous tissue, are called sutures. Sutures allow moulding or movement of the bony plates in labor and they also allow the baby’s brain to grow rapidly after birth. Fontanels: These are located where sutures intersect. They are membrane and skin- covered openings and spaces. The anterior and posterior fontanelles are the most important clinically. 3. Explain suture and fontanel locations, shapes, and functions in detail along with their names. Sutures • Sagittal suture—divides the cranial vault in half, runs between the parietal bones and it originates at the anterior fontanelle and ends at the posterior fontanelle. • Lambdoidal sutures (2)—these run from the posterior fontanelle down and around to the border of the occipital vault. These separate the interparietal portion of the occiput from the two parietal bones. • Coronal sutures (2)—these run transverse and downward from the anterior fontanelle to the sphenoid fontanelle on either side. The coronal sutures separate the parietal and frontal bones. • Frontal suture—this is location between the two frontal bones. It is an anterior continuation of the sagittal suture. It may be mistaken for the sagittal suture in deflexed presentations during an internal exam.

The skull is the receptacle for the most highly developed part of the nervous system, the brain and also for the sensory organs connected with it. The initial parts of the digestive and respiratory systems are located in this part of the skeleton. ©2017 Babuci Angela The skull The skull consists of two sets of bones: a) The cranial bones that form the neurocranium, which lodges the brain. b) The facial bones, which form the viscerocranium. The bones of the visceral skull form: . the orbits, . the oral cavity. the nasal cavity. ©2017 Babuci Angela The terms used for examination of the skull The frontal norm (norma frontalis). The shape of the skull is oval, but the upper part is wider than the lower one. In frontal norm the bones of the visceral cranium can be divided into three floors: a) The superior floor of the visceral cranium corresponds to the forehead. b) The middle floor includes the orbits and the nasal cavity. c) The inferior floor corresponds to the oral cavity. ©2017 Babuci Angela The lateral norm (norma lateralis).The skull is seen from the lateral side.

  • Skull and Facial Bones
    Skull base and vault By Dr.Safa Ahmed Rheumatologist (MSc.) Skull base • This represents the floor of the cranial cavity on which the brain lies. Bones of the base of the skull • 5 bones compose the base of skull: 1. Frontal bone 2. Temporal bones 3. Occipital bone 4. Sphenoid bone 5. Ethmoid bone Cranial fossa • It is formed by the floor of the cranial cavity. • It is divided into 3 distinct parts: 1. Anterior cranial fossa 2. Middle cranial fossa 3. Posterior cranial fossa Anterior cranial fossa • Formed by the following bones: 1. Orbital plate of frontal bone 2. Cribriform plate of ethmoid bone 3. Small wings and part of the body of sphenoid bone. Contents: frontal lobes of the brain. Middle cranial fossa • It is deeper than the anterior fossa. • Formed by parts of the sphenoid and temporal bones. • Contents: temporal lobes and sella turcica on which the pituitary gland lies. Posterior cranial fossa • It is the most inferior of the fossae • Mainly formed by the occipital bone. • Contents: cerebellum, medulla, pons. foramen magnum internal acoustic meatus Foramina in the base of skull • Foramen ceacum • Optic foramen: transmit the optic nerve and ophthalmic artery into orbit. • Foramen magnum: is an oval shaped foramen in the base of the skull that transmits the spinal cord as it exits the cranial cavity. • Foramen ovale: lies in the sphenoid greater wing and transmits several nerves. • Jugular foramen: transmit the cranial nerves (9th, 10th,11th) and internal jugular vein. • Internal auditory meatus: provide a passage for the 7th and 8th cranial nerves and artery to the inner ear.

The mandible: is divided into 2 halves /unite at the age of one year/ 3. The frontal bone: is formed of 2 halves /they start to unite at the age of 2 years & unite completely at 10 years/ 4. The calvaria (skull cap): is large because the brain is relatively large in size 5. The tuberosities, crests, lines are not pronounced. THE SKULL AT BIRTH 6. The presence of fontanelles a) Anterior fontanelle or frontal: a rhomboidal membrane between the 2 parietal bones & 2 halves of the frontal bone /closes at the age of 1-2 years/ b) Posterior fontanelle or occipital: a triangular membrane between the 2 parietal bones & the occipital bone /it closes at the age of 8 months/ c) Antero-lateral or sphenoid fontanelle /on each side at the region of the pterion, closes at the age of 3 months/ d) Postero-lateral or mastoid fontanelle /on each side at the region of the asterion, which also closes at the age of 3 months/ Fontanelles • The bones of the skull do not move but they show amazing patterns of growth during our lives. •In newborn different bony plates are not joined together. They are separated by gaps and these are the fontanelles. •In normal conditions 2 fontanelles exist: frontal and occipital.
