Q

what happens once the sperm penetrates the ovum?

A

fertilises it and combines their genetic material, so restores the 23 complemented pair chromosomes as the sperm and ovum only have 23 single chromosomes each

Q

what does mesoderm form?

A

muscles, bones, circulatory system, reproductive system
(Glasper et al, 2006)

17
Q

what does the endoderm form?

A

digestive and respiratory system
(Glasper et al, 2006)

18
Q

what should be established by around 4 and a half months in the fetus?

A

nervous system, cortical and subcortical structures, major fibre pathways, neurones now produced
(Glasper et al, 2006)

19
Q

what does the neonatal brain need to continue developing once born?
(Glasper et al, 2006)

A

inputs from the environment relayed by the sensory systems

20
Q

why does the brain need to continue developing once born?

A

shapes development and learning of nervous system, is evident in physical, intellectual, language, and social development
(Glasper et al, 2006)

21
Q

when does the cardiovascular system form ?

A

from third week
(Glasper et al, 2006)

22
Q

when does the gastrointestinal system form?

A

when the endodermal sheet folds over and forms primitive gut in week 3- 4
(Glasper et al, 2006)

23
Q

where do the lungs develop from?

A

mesoderm and endodermal layers
(Glasper et al, 2006)
