Question 6

the spinal cord arises from what embryological component?

Answer 6

the caudal end of the neural tube

Question 7

the embryological alar plate (which is separated from the basal plate by the longitudinal groove called the sulcus limitans) creates the…

Answer 7

dorsal posterior part of the spinal cord and becomes the sensory or afferent portion of the cord

Question 8

the embryological basal plate which is separated from the alar plate by the longitudinal groove called the sulcus limitans) creates the…

Answer 8

ventral (ant.) part of the cord and becomes the motor, or efferent, portion of the spinal cord, and therefore would contain ant. horn cells

Question 9

the lateral lip of the neural groove gives rise to the…

Answer 9

neural crest cells that dvp multipolar ganglion cells or autonomic ganglia, pseudounipolar cells of spinal and cranial nerve ganglia, leptomeningeal cells, schwann cells, melanocytes, chromaffin cells of the adrenal medulla and odontoblasts

Question 10

multipolar ganglion cells or autonomic ganglia, pseudounipolar cells of spinal and cranial nerve ganglia, leptomeningeal cells, schwann cells, melanocytes, chromaffin cells of the adrenal medulla and odontoblasts all come from

Answer 10

neural crest cells (the lateral lip ofthe neural groove)

Question 11

the rathke pouch is… and forms…

Answer 11

oral ectoderm that forms the ant pituitaru

Question 12

te neural tube gives rise to the… which is then divided into what two things?

Answer 12

the spinal cord, which then becomes the alar and basal plate

Question 13

what gives rise to the dorsal partof the spinal cord/becomes the sensory portion of the cord?

Answer 13

alar plate

Question 14

what gives rise to the ventral part of the spinal cord/becomes the motor portion of the spinal cord

Answer 14

the basal plate
