Cephalic axial skeletal-neural dysraphic disorders: embryology and pathology.
Three fundamental types of cephalic axial skeletal-neural dysrapic disorders are analyzed, including: cranioschisis aperta with encephaloschisis (anencephaly and/or exencephaly), cranioschisis occulta with occipital encephalocele, and the Chiari malformation (occipital bone hypoplasia) with compression, deformation and displacement of hindbrain, cerebellum, and medulla. Both clinical and experi...
متن کاملNotochordal-basichondrocranium relationships: abnormalities in experimental axial skeletal (dysraphic) disorders.
The notochordal-basichondrocranium relationships have been investigated in cranioschisis occulta with encephalocoele (CSO-EN) and in cranioschisis aperta with exencephaly (CSA-EX) which represent, respectively, a minimal and a severe form of experimentally induced axial skeletal (dysraphic) disorders. Although apparently different, these two malformations are considered to represent different d...
متن کاملEmbryology of neural tube development.
Neurulation is the process of forming the neural tube, which will become the brain and spinal cord. This article reviews the various cellular processes involved in neurulation and discusses possible roles of folate in this process.
متن کاملUnusual Spinal Dysraphic Lesions
Human tail and multiple spinal dysraphism are unusual congenital malformations. Human tail appeared as a prominent lesion from the lumbosacrococcygeal region, generally without connection between the tail and the neurospinal axis. Spinal dysraphisms are usually isolated, reaching 0.038% of incidence of multiple spinal dysraphisms in the same child. There were three cases described of unusual sp...
متن کاملCutting, pasting and painting: experimental embryology and neural development.
Through the use of the techniques of experimental embryology, developed by such pioneering artisans as Wilhelm Roux, Hans Spemann, Ross Harrison, Frank Lillie and Viktor Hamburger, as well as their scientific ‘children’, ‘grandchildren’ and more distant ‘relatives’, key principles of neural development have been elucidated (TIMELINE). Although the goal of experimental embryology seems rather si...
