Test Your Understanding of Embryonic Development and Metamerism

• The text discusses the location of the cellular or blastopore region.
• This region is located beneath the gray crescent area.
• The boundaries of the gray crescent area become less distinct during segmentation.
• The cellular or blastopore region initially appears as a groove.
• Developmental process in Urodels lasts for 24 hours at 18°C.
• The process involves external changes.
• No further information is provided about the external changes.
• The process of neurulation involves the formation of the neural tube from the neural plate.
• The neural plate is an area of ectoderm that becomes the nervous system.
• The neural plate folds inwards to form the neural groove, which then closes to form the neural tube.
• The neural tube becomes the brain and spinal cord.
• The somites are masses of mesoderm that become segmented structures in the body.
• The somites differentiate into sclerotomes, myotomes, and dermatomes.
• The mesoderm also forms the intermediate mesoderm and lateral plate mesoderm.
• The endoderm becomes the epithelial lining of the digestive tract, respiratory tract, and urogenital system.
• Metamerism is the repetition of body segments along the anteroposterior axis.
• Metamerism is regulated by homeotic genes.
