DAA Lecture Exam 3 Questions and
Answers
the central nervous system consists of - Answer-brain and spinal cord
the peripheral nervous system consists of - Answer-cranial nerves and spinal nerves
the autonomic nervous system consists of - Answer-sympathetic NS
parasympathetic NS
enteric NS
At what level does fusion of the neural folds start? - Answer-fusion starts at 4-6 somites
Neural folds become - Answer-neural crest cells
The neural tube will form? - Answer-brain and spinal cord
The neural crest will give rise to - Answer-all of the neurons whose cell bodies are located outside the
CNS in the peripheral nervous system (PNS), Consisting of nerves, ganglia, and plexuses
,derivatives of the neural tube include - Answer-neurons of the CNS
Supporting cells of the CNS
Lower motor neurons of the CNS
Preganglionic autonomic neurons of the CNS
derivatives of neural crest - Answer--sensory neurons in the PNS
-Postsynaptic autonomic neurons
-schwann cells
-adrenal medulla cells
-head mesenchyme
-melanocytes in the skin
-arachnoid and pia mater of meninges (dura mater from mesoderm)
white matter of spinal cord contains - Answer-myelinated axons
gray matter of the spinal cord contains - Answer-neuron cell bodies
dorsal horn contains - Answer-sensory neurons
ventral horn contains - Answer-motor neurons
3 major events during the neuronal developmental process - Answer--proliferation
-migration
-differentiation
, after 6 weeks the marginal zone of the spinal cord turns into - Answer-white matter of the spinal cord
after 6 weeks of development the basal plate of the spinal cord turns into - Answer-ventral gray horn
after 6 weeks of development the alar plate of the spinal cord turns into - Answer-dorsal gray horn
what is found in the marginal zone of a developing spinal cord? - Answer-axons, white matter
neural crest includes - Answer-peripheral neurons
