Nervous system


1- What is the content of the gray and white matter of the nervous system and what is their
distribution in the cerebrum, cerebellum and spinal cord?


2. What glia occur in the central and peripheral nervous system and what is their function? What is
the structural nature of the blood-brain barrier and why is this barrier so important?


3. Which layers of the isocortex contain pyramidal neurons and what is their function. What is the
function of horizontal cells of Cajal?


4. In what way and by which interneurons are connected Purkinje cells of the cerebellum? What is
the function of Purkinje cells?


5. Where in the dorsal spinal cord can you find motor neurons? What types of interneurons occur in
the spinal cord?


6. What envelopes protect the CNS organs and what protects axons in the peripheral nerve?


7. What parts does the CNS ventricular system contain? What is the lining of ventricles and what is
their content?


8. What chemical substance makes up myelin and what is the significance of myelin. How does myelin
loss manifest itself in case of degenerative disease? Give an example of this disease.


9. When does the neural tube close during development and what layers can be distinguished in the
wall of this tube (histogenesis)? Which primary and secondary brain vesicles are formed during
development of the brain?


10. How does crista neuralis arise and what are its derivatives?
