The first and second arches disappear early. A remnant of the 1st arch forms part of the maxillary artery, [3] a branch of the external carotid artery. The ventral end of the second develops into the ascending pharyngeal artery, and its dorsal end gives origin to the stapedial artery, [3] a vessel which typically atrophies in humans [4] [5] but persists in some mammals.
Takayasu's arteritis (TA), also known as aortic arch syndrome, nonspecific aortoarteritis, and pulseless disease, [2] is a form of large vessel granulomatous vasculitis [3] with massive intimal fibrosis and vascular narrowing, most commonly affecting young or middle-aged women of Asian descent, though anyone can be affected.
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 .
Type B: The aortic arch is interrupted between the left common carotid artery and the left subclavian artery. This is the most common form of the condition, and is the classification most often associated with DiGeorge syndrome. [2] [5] Type C: The aortic arch is interrupted between the innominate artery and the left common carotid artery. This ...
The first pharyngeal arch, also mandibular arch (corresponding to the first branchial arch of fish), is the first of six pharyngeal arches that develops during the fourth week of development. [10] It is located between the stomodeum and the first pharyngeal groove .
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.
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 ...
Most are located above the aortic arch, [2] while some are located on the posterior side of the aortic arch between it and the pulmonary artery below. [3] They consist of glomus cells and sustentacular cells. [1] Some sources equate the "aortic bodies" and "paraaortic bodies", while other sources explicitly distinguish between the two.
