The Sequence in Appearance and Disappearance of Impressiones Gyrorum Cerebri and Cerebelli

We investigated the sequence and the intensity in the appearance and the disappearance of the impressiones gyrorum cerebri and cerebelli, of juga cerebralia and cerebellaria and of juga cerebellaria interlobularia in the collection of 34 macerated and disarticulated skull bones from the newborn to 30 years of age (68 specimens/halves of skulls) and 19 skulls in the period from 30 to 80 years of age (38 specimens). Juga cerebralia on the squama of the temporal bone and cerebral lamina of the frontal bone appeared already in the course of the first year of life, much earlier than cited in the literature. The intensity of the development of juga cerebralia increased to the third decade. After that age, the intensity decreased gradually, and the juga cerebralia disappeared completely in parietal bones, in the cerebral fossae of the occipital bones and finally in most cases also on the cerebral lamina of the frontal bones. Juga cerebellaria and impressiones gyrorum cerebelli appeared in the middle of the second year of age and persisted to the ten years of age, which coincides with the closure of the fissures among the parts of the occipital bone. Jugum cerebellare intersemilunare appeared in the first year of life and persisted in its complete length, or interrupted in different sections of its course, during the whole life. The intensity in appearance of juga is partly influenced by the increasing thickness of the diploe

Postnatal development of lower jaw in patients with Down syndrome

Na temelju usporednih istraživanja, autori su utvrdili, da je u osoba s Downovim sindromom, donja čeljust manja, a to smanjenje je u odnosu na donje čeljusti normalnih osoba više u pogledu visine ramusa, nego u pogledu dužine ii širine donje čeljusti. Kut donje čeljusti je u mongoloida veći, tj. tuplji, dok su vertikalni položaj i inklinacija nepromijenjeni. Autori smatraju da su, u osoba s Downovim sindromom, nisko položena uška i najvjerojatnije makroglosija, posljedica zaostalog razvoja donje čeljusti, s obzirom na smanjenu zapremninu usne šupljine.On the basis of the comparative studies the authors have found a reduced lower jaw in persons with Down syndrome. This reduction as compared to the lower jaw in normal persons is greater with respect to the ramus height than with respect to the length and width of the lower jaw. The angle of the lower jaw is greater in mongoloids, i.e. more obtuse, while the vertical possition and its inclination are unchanged. The authors maintain that in persons with Down syndrome a low position of the ear and most probably macroglossity result from the retarded development of the lower jaw, or that a low position and macroglossity are relative with respect to the reduced volume of the oral cavity

The Fate of the Arachnoid Villi in Humans

Villi arachnoidales undergoes in the course of life changes in relation to the skull bones and sinuses. Our aim was to determine the relations of the villi arachnoidales to the skull bone and/or sinuses from the neonatal period to adults. The investigations were performed on collection of 50 disarticulated macerated skull bones from the newborn to 30 years of age and on 20 skulls from individuals in the life period from 30 to 80 years of age. Villi arachnoidales produced imprints on the skull bones in the shape of holes and/or furrows corresponding to different shape of the villi arachnoidales. These imprints appeared very early in the period when the bony sprouts of the large skull bones received a thin covering of compact bone, the future lamina vitrea. At that time villi arachnoidales had no connection with the dural sinuses but with the diploe and with the diploic veins. By agglomeration of the villi in larger and large formations, granula meningea, Pacchionian granulations, the contact to sinuses was realized by means of short channels. The structural changes of villi arachnoidales may produce thrombophlebitis and hydrocephalus externus, especially in children. The fate and the relations of the villi arachnoidales are therefore of great importance for neurologist, neurosurgeon and otorhinolaryngologist

Functional anatomy of the knee joint and the upper tibiofibular joint

The authors describe in detail the clinical and functional anatomy of the knee joint and of the upper tibiofibular joint. They pay special attention to the morphology of the synovial membrane in connection with its significance in clinical medicine and especially in rheumatology. The blood supply and the innervation if the above-mentioned joints are also described very precisely. In the pathology of the knee joint a special role belongs to the ligaments and to the menisci. Their morphology and functional anatomy are, therefore, described in detail with special regard to injuries of the lateral meniscus are discussed. Also discussed is the possibility of the demonstration of the upper tibiofibular joint on an appropriate x-ray pictures. The intention of the authors was to provide, through their minute study of functional anatomy of the knee joint and the upper tibiofibular joint, a contribution to the knowledge of clinical symptomatology of the mentioned joints

Lost and found anatomical terms: crista choanalis vomeris

Pars cuneiformis vomeris and crista choanalis are morphological structures on the vomer listed in the current official anatomical nomenclature, Terminologia anatomica, but are either not mentioned or incorrectly described in different anatomical books. The term crista choanalis vomeris was originally proposed by Drago Perović in 1958 to describe the vertical crest beginning at the angle of the alae vomeris, running downwards to the posterior free margin of the vomer. Perović also described the part of the vomer behind this crest was shaped as a cone, and termed it pars cuneiformis vomeris. Because of their important contributions to the function of the respiratory pathway, crista choanalis vomeris and pars cuneiformis vomeris deserve proper definitions in the anatomical terminology
