Development of Nervous system

Question 1

Cortico-neurogenesis

Answer 1

neurons in the cerebral cortex are created, organized, and connected during brain development

Question 2

Human Brian development: A

Answer 2

specialized cells called the notochord induce the ectoderm cells to become the primitive nervous system

Question 3

human brain development: B

Answer 3

neuroepithelium folds over becoming the neural folds

Question 4

human brain development: C

Answer 4

the precursor of the brain and spinal cord, the neural tube is formed

Question 5

human brain development: D

Answer 5

neural crest cells migrate and initiate development of body structures3

Question 6

proliferation

Answer 6

rapid cell division

Question 7

migration

Answer 7

neurons move to their destinations

Question 8

differentiation

Answer 8

neurons specializes

Question 9

synaptogenesis

Answer 9

formation of connections

Question 10

myelination

Answer 10

insulation of axons

Question 11

pruning

Answer 11

elimination of unnecessary connections

Question 12

human brain development: after birth

Answer 12

brain grows rapidly especially in synaptogenesis and myelination with the prefrontal cortex maturing into early adulthood

Question 13

gestational brain development: first trimester

Answer 13

neural tube forms giving rise to forebrain midbrain and hindbrain while neurons begin forming and migrating

Question 14

gestational brain development: second trimester

Answer 14

rapid neuron production, cortical layer formation, early synapse creation, and the beginning of gyrification

Question 15

gestational brain development: third trimester

Answer 15

brain volume increases, synaptic connections are refined, and myelination begins improving signal transmission

Question 16

gestational brain development: late gestation to early postnatal life

Answer 16

cortical and subcortical connections strengthen and the prefrontal cortex, crucial for cognitive functions, starts maturing
