BIO 351 MODULE 3 (2026/2027) QUESTIONS
AND CORRECT ANSWERS GRADED A+
The neural tube is regionalized by developmental gene regulation. Which of the
following correctly matches the gene and specified region?
Shh - ventralizing the neural tube
Which of the following regulates the segmentation of the hindbrain rhombomeres?
Hox gene expression
Which of these central nervous system structures are correctly listed in a rostral to
caudal order?
Cerebrum, Pons, Spinal Cord
Which of the following represent antagonistic cues used in patterning the
rostral/caudal axis if the neural tube:
RA/FGF8
, In the diagram of neural tube folding, indicate the region of tissue that will
eventually form the neural crest.
C
The process the neural crest cells use to delaminate from the dorsal neural tube is
__________ .
EMT, epithelial mesenchymal transition
Neural crest cells derive from the [ Select ] layer and give rise to the [ Select ].
ectoderm
peripheral nervous system
Neural crest cells can differentiate into multiple cells types. The following
statement is TRUE or FALSE: A unique feature of neural crest cells is that they
have intrinsic programs that predetermine their fate prior to delamination from the
neural tube; Neural crest cells are not influenced by extrinsic cues to instruct the
outcome of the ultimate cell fate.
False
In developing radial glia, ____________ and _________ are necessary to maintain
the progenitor state. Pick the best answer to fill in the blank below
Notch, Par3
