Right-sided aortic arch is a rare anatomical variant in which the aortic arch is on the right side rather than on the left. During normal embryonic development, the aortic arch is formed by the left fourth aortic arch and the left dorsal aorta. In people with a right-sided aortic arch, instead the right dorsal aorta persists and the distal left ...
A double aortic arch; occurs with the development of an abnormal right aortic arch in addition to the left aortic arch, forming a vascular ring around the trachea and esophagus, which usually causes difficulty breathing and swallowing. Occasionally, the entire right dorsal aorta abnormally persists and the left dorsal aorta regresses in which ...
Aortic arch anomaly - peculiar facies - intellectual disability is a rare, genetic, congenital developmental anomaly that is characterized by heart abnormalities, cranio-facial dysmorphia, and intellectual disabilities. No new cases have been reported since 1968.
The aortic arch, arch of the aorta, or transverse aortic arch (English: / eɪ ˈ ɔːr t ɪ k / [1] [2]) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea .
The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 1 ]
The anterior communicating artery connects the two anterior cerebral arteries and could be said to arise from either the left or right side. All arteries involved give off cortical and central branches. The central branches supply the interior of the circle of Willis, more specifically, the Interpeduncular fossa.
Double aortic arch is a subtype of complete vascular ring. There are three types of double aortic arch: Right dominant arch (about 70% of surgical cases) Balanced or codominant (about 5%): both arches are of equal size; Left dominant (about 25%) Double aortic arch with right dominant arch: Normally there is only
Intense emotional stimuli that cause stress can lead to alterations in cardiovascular function. [6] The right insular cortex probably plays the most significant role in these phenomena. Similar lateralization is probably involved in cardiovascular malfunction in patients with head injury, stroke, multiple sclerosis, brain tumors, meningitis and ...
