Deck 15: Nervous System

Question 1

________ Floor of the diencephalon

A)A
B)B
C)C
D)D
E)E

Answer 1

C
The floor of the diencephalon gives rise to the infundibulum (the primordium of the neurohypophysis)and the mammillary bodies.The infundibulum gives rise to the median eminence,the infundibular stem,and the pars nervosa.The infundibulum initially has a thin wall,but its distal end soon becomes thickened as the neuroepithelial cells proliferate.These cells later differentiate into pituicytes.

Question 2

________ Gracile nuclei

A)Neural crest cells
B)Alar plates
C)Basal plates
D)Neuroepithelium
E)Spinal ganglion cells

Answer 2

B
The gracile and cuneate nuclei develop from neuroblasts that migrate from the alar plates into the marginal zone of the myelencephalon.These nuclei are associated with correspondingly named tracts that enter the medulla from the spinal cord.

Question 3

________ Third ventricle

A)A
B)B
C)C
D)D
E)E

Answer 3

D
The third ventricle is formed mainly from the cavity of the diencephalon.The anterior part of the third ventricle is derived from the cavity of the telencephalon.
