Hi,
Does the brain control the physical growth of a human baby?
I think if, for some unfortunate reason, the brain is absent, the growth would still take place normally but more like a vegetable. I don't think if the brain is absent, one can even blink the eye or move a finger. But the details and data for organ growth such as size and shape, tallness, color, hair color, sex, etc. are present in each cell; in other words each cell has its own 'brain' which tells it how to grow. I think heart and lungs can also work independently of brain because the persons in coma without any brain activity can still pump blood around and breathe. It's possible that in absence of brain the functioning of heart and lungs is not that as smooth and reliable.
I don't think that hypothalamus, pineal gland, and pituitary gland are integral parts of brain so if the brain is absent, the glands could still be there to release the required hormones.
Could you please confirm if I'm thinking along the right lines? Thank you!
