    The anastomotic artery connecting the axillary or brachial artery to one of the forearm arteries
    (2000) Uzun A.; Seelig Jr. L.L.
    A vessel connecting the axillary or brachial artery to one of the forearm arteries was found in a 65 year old male cadaver, during the gross anatomy dissection of the upper extremity of 20 adult cadavers at the Department of Cellular Biology and Anatomy, Louisiana State University Medical Center. The right radial artery originated from the brachial artery nearly at the usual level and was connected to the axillary or brachial artery by a long slender anastomotic artery (vasa aberrantia). The anastomotic artery coursed under the medial side of the biceps muscle between the median and musculocutaneous nerves, and gave off two muscular branches to the biceps muscle. The anastomotic artery coursed between the median and musculocutaneous nerves in the arm, it passed to the forearm under the bicipital aponeurosis and connected the main radial artery on the radial side of the forearm. The anastomotic artery can be explained on the basis of its embryologic development and also ought to be distinguished from the other common arterial variations in the upper extremity.

    Congenital malformations of the central nervous system
    (2001) Uzun A.; Aydin N.E.
    Congenital malformations of the central nervous system are common. They have assumed increasing importance in recent years because of sophisticated diagnostic methods and possibilities for genetic counselling and antenatal diagnosis of the abnormal fetus. Malformations may be primary or secondary; this review deals with primary malformations of the central nervous system. Chromosomal abnormalities can be inherited from a parent or new mutations can occur. Teratogens are external agents that alter a normal embryologic process in some way. When examining a case of congenital malformation, the morphologist should try to determine the specific features of the malformation and indicate, if possible, how that malformation may have been caused. Approximately 3 % of newborns have major malformations. About 60 % of congenital malformations are of unknown cause, and about 20 % are due to interactions between hereditary tendencies and nongenetic, usually undefined factors. There must be close cooperation between the morphologists and clinicans for precise understanding of the central nervous system malformations.
