miracles of growth

The believers are those whose hearts tremble when God is mentioned, whose faith is increased when His Signs are recited to them, and who put their trust in their Lord; those who perform prayer and give of what We have provided for them. They are, in truth, the believers. They have high ranks with their Lord, as well as forgiveness and generous provision. (Qur’an, 8:2-4)

The Miracle of Growth

The pituitary gland, a small, pink piece of flesh about the size of a chickpea, is connected to the hypothalamus region, located underneath the brain, by a small stalk. This connection allows it to receive instructions directly from the hypothalamus and thus produce the requisite number of hormones and make the necessary bodily adjustments. One of these adjustments is growth.
A person’s growth assumes two different forms: an increase in the volume of certain cells, and the division and multiplication of cells. The growth hormone brings about and directs both processes. Secreted by the pituitary gland, this hormone affects all of the body’s cells. Every cell understands the message it receives from the pituitary gland. If growth is necessary, it grows; if it needs to divide and multiply, it does so.
For instance, a new-born baby’s heart is about one-sixteenth the size of an adult’s,30 even though the total number of cells in both hearts is the same. The growth hormone, which affects the heart cells individually during the growth process, commands every cell to grow to the necessary extent. As the heart grows, it turns into an adult, human heart.
Other cells, such as muscle and bone cells, divide and multiply throughout the developmental period. Again, the growth hormone is responsible for telling them how much they need to divide.31
The growth hormone’s great affect on each cell is an exceedingly great miracle. Were only some cells to follow its instructions, the result would be crippling. For example, if the heart cells grew in the manner dictated by the growth hormone and the ribcage’s cells refused to do so, the growing heart would be so constricted within the non-growing ribcage that the person would die. Or, if the bridge of the nose grew while the skin did not, the bridge would burst through the skin.
All of the muscles, bones, organs, and the skin grow in harmony with one another. This flawless harmony is ensured by each individual cell’s obeying the growth hormone. That being the case, we need to ask how this chick-pea-sized gland comes to know the necessary formula for a cell’s division or growth.
At this point, the flawlessness and perfection of God’s creation emerges once again. Cells in a tiny region bring about the division and growth of trillions of other cells within a specific order. Yet these cells do not see the human body from the outside or know how much it needs to grow or what stage it has reached. These unconscious cells produce the growth hormone, within the darkness of the body, without knowing what it is that they are doing. Furthermore, they also halt production at the appropriate time.
All of these intricate details about the growth hormone and all of these interconnected balances indicate a single truth: God created humanity at a specific time and in a flawless manner. In fact, God reveals the superior nature of His creation in the following verse:

He is God—the Creator, the Maker, the Giver of Form. To Him belong the Most Beautiful Names. Everything in the heavens and Earth glorifies Him. He is the Almighty, the All-Wise. (Qur’an, 59:24)
