Chapter 50, Problem 9TYK

In the embryonic development of the eye:

a. the optic vesicle cells permanently adhere to each other to prevent movement, whereas the optic cup cells are very motile.

b. the optic cup induces the surface ectoderm to form the lens placode.

c. gradients determine that the ectoderm overlying the lens vesicle develops into the optic vesicle.

d. microtubules powered by myosins and microfilaments powered by dyneins move the eye components around in the head region.

e. cadherins function in the presence of calcium to allow the lens placode and optic cup to break apart.

Which of the following is an illustration of permissive interaction? The epidermis signals the underlying dermis to create condensations and the dermal condensations then signal the epidermis to form specific cutaneous structures. Wing epidermal epithelium produces wing feather when exposed to wing dermal mesenchyme but will produce scales and claw when exposed to foot dermal mesenchyme. When implanted in the newt embryo, the frog oral ectoderm can only differentiate into frog derivatives and will not differentiate into newt derivatives. D An inducing signal from the optic vesicle is necessary for new gene expression in the lens ectoderm. E) Contact with the appropriate extracellular matrix is sufficient for cells to express differentiation-specific genes.
Observations of the developing chick embryo reveal that skeletal muscles develop from the transplanted somites even though motor neurons innervating those muscles arise from chick neural crest cells. Based on these observations, what is MOST likely true?   A. Neural crest cells differentiate into somites.   B. Neural crest cells fuse with developing somite cells.   C. Neural crest cells develop from migrating somite cells.   D. Neural crest cells send projections into developing somites.
What are the pathways through which a neural tube defect can occur? Select one or more: V A. Failure of initiation of neural tube closure V B. Failure to fuse the elevated neural folds V C. Abnormalities in adhesion of surface ectodermal cells V D. Altered differentiation of neuromesodermal progenitors at the sacral level
