51
Q

type of brain scan used to examine brain activity or functioning

A

PET and fMRI

52
Q

brain scans to limit

A

CT bc they use x rays

53

which germ layer becomes skin and nervous system

55
Q

germ layer becomes organs and glands

56
Q

germ layer becomes bones and muscles

57
Q

17 days post conception what part of ectoderm folds and what does it become

A

rostral is brain, caudal is spinal cord

59
Q

disorder occurring when rostral end of neural tube doesn’t fully close v when caudal end doesn’t fully close
