Observations were made on 299 dry human mandibles and 21 autopsy heads. Foramina were observed in the inner surface of the alveolar part in 32% of the mandibles investigated. The diameter of the foramina varied between 0.4 mm and 1.6 mm. In most instances foramina were present between the lower medial and lateral incisors but in some cases they were also… (More)
BACKGROUND Children with multisystem involvement including congenital heart defect (CHD) are a very salient problem. The purpose of this study was to evaluate the incidence of CHD associated with malformations of other systems and to assess the modalities of treatment and perioperative mortality among patients referred to the department of pediatric cardiac… (More)
Although accessory foramina of a human mandible are consistent findings their contents still causes confusions. The study was undertaken to determine the contents of accessory foramina on the medial aspect of mandibular symphysis. Dissection of 21 human cadaveric heads revealed the presence of neurovascular bundle in accessory foramina. Macroscopically it… (More)
In embryos at stage 13th vestibulocochlear ganglion forms a complex structure with the geniculate ganglion. The geniculate ganglion is placed rostrally and may be distinguished from the vestibulocochlear ganglion. Also at this stage there is a sign of differentiation of the vestibular and cochlear ganglia.
The formation of the myelin sheath of the human phrenic nerve has been studied by electron microscopy in fetuses aged 15, 17, and 23 postovulatory weeks. At 15 weeks, the phrenic nerve is composed mainly of large bundles of axons surrounded by lemmocyte processes. However, fibres at the beginning of myelination are present and show one or one and a half… (More)
The formation of the myelin sheath of the human hypogastric nerves was studied by electron microscopy in a foetus of 23 weeks of postovulatory age (220 mm C-R length). In the investigated foetus the hypogastric nerves were mainly composed of bundles of unmyelinated fibres. The myelinated fibres were seen to be at different stages of myelination. Well… (More)
Investigations were made on serial sections of human embryos at developmental stages 16 and 17 (37-41 days). The spinal nucleus of the accessory nerve presents well delimited cellular group in the dorsplateral part of the ventral horn of the spinal cord. The migration zone is still present. In embryos of stage 16 the spinal accessory nerve joints the fibers… (More)
