AORTIC ARCHS Meaning and
Definition
-
Aortic arches refer to a series of paired arterial arches that are present in the embryonic stages of all vertebrates, including humans. These arches are the foundational structures of the circulatory system, serving as vital pathways for the transportation of oxygenated blood from the heart to different regions of the body.
In vertebrate embryos, the aortic arches arise from the aortic sac, a tubular structure formed by the fusion of branchial arch arteries. As the embryonic development progresses, the aortic arches undergo significant transformations to ultimately form the major blood vessels of the adult circulatory system.
In humans, aortic arches start to develop during the fourth week of gestation. Initially, there are six pairs of aortic arches; however, only three pairs are retained in the mature structures. These three aortic arches are identified as the first (mandibular), second (hyoid), and third (stapedial) arches. The first and second aortic arches, although transient, contribute to the formation of certain vital blood vessels, including parts of the maxillary artery, stapedial arteries, and hyoid artery. The third aortic arch gives rise to the carotid arteries, which supply oxygenated blood to the head and neck.
The aortic arches play a crucial role during the embryonic development of the circulatory system and contribute to the establishment of the final arterial connections. Their correct formation and subsequent remodeling are crucial for the overall health and functioning of the cardiovascular system.

Etymology of AORTIC ARCHS
The word "aortic" comes from the Latin word "aorticus", which means "of the aorta". The term "aorta" itself is derived from the Greek word "aortē", meaning "the great artery". The word "arch" in this context refers to the curved structure or bend that the aorta forms as it arises from the heart and then branches out into smaller arteries. So, "aortic arches" refers to the curved structures formed by the aorta.
