branchial arch การใช้

• Examples of detectable evidence of vestigially metameric structures include branchial arches and cranial nerves.
• In addition, this transcription factor plays an important role in limb and branchial arch development.
• By day 10.5, the branchial arch and limbs also begin to express " Osr1 ".
• Since the branchial arches are important developmental features in a growing embryo, disturbances in their development create lasting and widespread effects.
• In one region, neural crest cells develop into five structures _ the branchial arches _ which grow to form the face.
• It is widely accepted that there is a factor within the tissues of the first branchial arch that is necessary for the development of teeth.
• Crouzon was the first to describe a condition he called " craniofacial dysostosis ", defined as a genetic branchial arch disorder that results in abnormal facial features.
• The branchial imprint is preserved in great detail, parts of both the right and left baskets having been preserved, and the posterior five branchial arches being well defined.
• Other animals that would later be classified as temnospondyls were placed in a group called Ganocephala, characterized by plate-like skull bones, small limbs, fish-like scales, and branchial arches.
• "' Gill rakers "'in fish are bony or cartilaginous processes that project from the branchial arch ( gill arch ) and are involved with suspension feeding tiny prey.
• In a developing embryo " JAG1 " expression is concentrated around the pulmonary artery, mesocardium, distal cardic outflow tract, major arteries, metanephros, branchial arches, pancreas, the portal vein, and otocyst.
• Its expression is first noticed in embryonic day 9.5 ( E9.5 ) in the splanchnic mesoderm caudal to the level of the heart and foregut pocket, and in the branchial arches.
• "Osr1 " is expressed in the first and second branchial arches, in the limb buds, mouth and nasal pits, in the trunk, the forebrain ., developing somites, distal mandible and developing eye.
• The "'aortic arches "'or "'pharyngeal arch arteries "'( once referred to as "'branchial arches "'in human embryos ) are a series of six paired embryological vascular structures which give rise to the great arteries of the neck and head.
• Like Erik Jarvik, he has argued that the three ear ossicles of mammals can be derived from components of the hyoid branchial arch of osteolepiforms rather than from both the mandibular and hyoid arches as claimed by the Reichert Gaupp theory.
• In fish, the hypoxic signal is carried up to the brain for processing by the branchial arch is innervated by the glossopharyngeal nerve ( cranial nerve IX ); however all four arches are innervated by the vagus nerve ( cranial nerve X ).
• The furcula is at first separated from the tuberculum impar by a depression, but later by a ridge, the "'copula "', formed by the forward growth and fusion of the ventral ends of the second, third, and part of the fourth branchial arches.
• ""'Huffmanela ossicola " "'is a parasitic nematode It has been observed in the branchial arch bone and the spinal cord bone ( as well as others ) of the labrid marine fishes " Bodianus loxozonus ", and " Bodianus perditio " caught off New Caledonia.
