BACKGROUND The sciatic nerve, as the terminal branch of the sacral plexus, leaves the pelvis through the greater sciatic foramen beneath the piriform muscle. Afterwards, it separates into the tibial and the common peroneal nerve, most frequently at the level of the upper angle of the popliteal fossa. Higher level of the sciatic nerve division is a(More)
An unpaired trunk forming part of the anterior cerebral arteries, the so-called azygos pericallosal artery, was found in a male fetus among a collection of 200 fetuses. The morphological characteristics of the trunk and the anterior cerebral arteries at the "preazygos" and the "postazygos" segments were examined using an operating microscope. The azygos(More)
OBJECTS Carotid-vertebrobasilar anastomoses-the trigeminal, otic, hypoglossal, and proatlantal intersegmental arteries-serve as transitory channels between primitive internal carotid arteries and bilateral longitudinal neural arterial plexus, which is the precursor of future basilar artery, when the human embryo reaches about 4-mm length. MATERIAL AND(More)
Myelinated nerve fibers suffer from different degrees of atrophy with age. The success of subsequent regeneration varies. The aim of this research was to analyze myelinated fibers of the human sciatic nerve during the aging process. Morphometric analysis was performed on 17 cases with an age range from 9 to 93 years. The outer and inner diameter of 100(More)
Two rare cases of the circle of Willis are presented. One of them represents a fetal circle of Willis (crown-rump length, or CRL, 17 cm), the other one is adult circle from a male cadaver 65 years of age. Arterial variations and abnormalities of the represented circles of Willis are described. Interpretation of the appearance of variations and abnormalities(More)
The sural nerve is the most frequently used sensory nerve in nerve transplantation. It can be transplanted alone or together with the other elements of the neurovascular stalk within the superficial sural flap. The aim of this study was to define the morphologic types of the sural nerve complex, as well as to describe their specific characteristics.(More)
Number of sclerotic glomeruli increases during the aging process. Consequently, majority of remained nonsclerosed glomeruli become hypertrophic and some of them sclerotic, too. The aim of this study was to quantify the size and connective tissue content of nonsclerosed glomeruli and to evaluate the percentage of hypertrophic ones in examined human cases(More)
BACKGROUND Although centuries of the human CAC research are behind us, still there is a stimulus for the authors to describe something new or to add to the "archive" of already known facts about its angioarchitecture. METHODS With normal configurations of the posterior part of the CAC in early prenatal status, 172 brains of human fetuses from the 13th to(More)
OBJECT The authors describe some of the features of the medial striate branch or recurrent artery of Heubner (RAH). This structure has indisputable functional, neurological, and neurosurgical significance, and originates from the A(1) and/or A(2) segments of the anterior cerebral artery. METHODS Microdissection of 94 human fetal specimens was performed.(More)
OBJECTIVE Although complex and varied, adult cerebral angioarchitecture has its origins in embryologic development, where normal components, variations, and abnormalities evolve from modifications of primitive vessels. Therefore, the aim of this report was the study of the morphologic features of the basilar fenestrations in prenatal and postnatal period(More)
