Across
- 4. blocks of tissue that lead to the formation of segmental structures such as vertebrae
- 5. formed from ectoderm above notochord; contains neural folds on lateral edges
- 6. located along sides of neural tube after pinching off from ectoderm; migrate to different parts of the body to form cells of different structures
Down
- 1. a group of cells or tissues influences another through close range interactions
- 2. flexible rod of mesodermal cells that runs along the anterior-posterior axis of a chordate in the dorsal part of the body(later becomes vertebrae)
- 3. infolded ectodermal clefts in vertebrates that will give rise to the nervous system
