Describe in detail the development of the neural tube, early
brain and spinal cord development in vertebrates complete with
relevant signaling systems.
Precursors of neural cells (neural tube) are able to separate
from the precursors of epidermal cells because: a. All of the above
b. Differential adhesion occurs c. E-cadherin expression is
decreased in neural precursors d. N-cadherin expression is
increased in neural precursors.
Cadherin adhesion proteins are described by the following,
except?
a.
Transmembrane proteins that can interact with cadherins on other
cells
b.
Crucial to the differential adhesion of cell types
c.
Binding to fibronectin in the extracellular matrix
d....
The ____________, which is region closest to the neural tube
lumen contains mostly neural stem cells. a. Ventricular zone b.
Mantle c. Marginal zone d. All of the above
Briefly describe the process of protein folding. In your
description comment on the various models that help describe
protein folding, the value of using a “Folding Funnel” to describe
the folding process, and the role of chaperones and chaperoning in
in vivo folding.
20. Which of the following occurs as a result of the neural
tube defect?
a. Anencephaly
b. Holoprocencephaly
c. Microcephaly
d. Syringomyelia
e. Corpus callosum agenesis
21. Vascular disease involving the aorta, carotid and
ophthalmic arteries in elderly patients, which of the
following?
a. Wegener granulomatosis
b. Takayasu disease
c. Polyarteritis nodosa
d. Kawasaki disease
e. Giant cell arteritis
22. What is the inflammatory bowel disease characterized by
the development of pseudopolyps with mucosal regeneration and the
development of pseudopolyps...
Look at the major divisions of the brain and the developing
neural tube. Do you see a pattern in the position of each tube and
the functions of the major brain divisions?
