Pattern formation and Morphogenesis

Question 1

morphogenesis

Answer 1

• creation of a well ordered form
• cell and tissue movement to give 3D shape
• coordinated with cell proliferation, differentiation, migration, cell death
• tissue arranged in a precise pattern

Question 2

pattern formation

Answer 2

• embryonic cells… acquire identities… leads to well ordered spatial and temporal pattern of cell activities…. spatially organized structure develops
• establishment of overall body plan

Question 3

body plan

Answer 3

• organization of an organism
• anterior, posterior, dorsal, ventral, left, right

Question 4

other terms for anterior posterior synonyms

Answer 4

• cranial-caudal (craniocaudal)
• rostral-caudal (rostrocaudal)
• cephalic-caudal (cephalocaudal)

Question 5

planes of symmetry

Answer 5

• frontal plane
• transverse plane
• sagittal plane

Question 6

phases of pattern formation

Answer 6

• formation of body axes (breaking symmetry)
• organization of the embryo into smaller regions - segments
• segments develop specific characteristics
• tissues and organs are produced
