Essential roles of the winged helix transcription factor
The carotid and aortic arches, where O 2 chemoreceptors are located in mammals, are believed to be derived from the gill arches of an aquatic vertebrate ancestor (Figure 1, Romer, 1962). principles of human anatomy 13th edition pdf components of each pharyngeal arch include an aortic arch, a specific cranial nerve and associated muscle, and a cartilage skeleton. The adult derivatives of each of these components are reviewed. LEARNING OBJECTIVES: You should be able to: a. List the developmental stages and the rostrocaudal sequence in which the pharyngeal arches are visible externally in the human embryo. b. List the. Importance of ethics in research pdf

Aortic arches of tetrapods - embryos have 6 pairs of aortic arches: but the 1st & 2nd arches are temporary & not found in adults the 3rd aortic arches & the paired dorsal aortas anterior to arch 3 are called the internal carotid arteries

  • arch) become the carotid body in higher vertebrates associated with the regulation of ventilation and ensuring oxygen supply to the gas exchange surface. Those receptors associated with the second gill arch (fourth branchial arch) become the aortic bodies capable of sensing changes in oxygen
  • The mature aortic arch and great vessels derive from the embryonic pharyngeal arch arteries (PAAs) and the aortic sac. The PAAs are components of the pharyngeal apparatus, a vertebrate-specific structure comprising alternating bulges (arches) and indentations (pouches and clefts) that develops sequentially along the body axis in a head-to-tail direction. The pharyngeal arches are overlaid by
