The Spinal Cord
In Part 6 (The Amazingly Designed Human Body – Part 6), we started our discussion on the nervous system. Starting with the central nervous system first we focused our attention on the brain. Today we will take a look at the rest of the central nervous system – the spinal cord.
In the last section, we compared the brain to a supercomputer. To continue that same comparison, the spinal cord would be compared to the cable(s) running from the supercomputer and the network routing station that divides the information system to the rest of the network or body.
The spinal cord is a collection of nerve fibers and tissue about the diameter of an average finger that runs from the medulla oblongata at the base of the brain to the second lumbar vertebra of the lower back. The lower end of the spinal cord terminates in a fibrous bundle known as the filum terminale. The filum terminale helps to secure the spinal cord to the end of the spinal column as it runs down through the hollow center of the vertebra. There is a lining of spinal fluid that lies between the spinal cord and the vertebra to cushion it and help keep it from being damaged by direct contact with the boney vertebra.
A series of nerves branch off from the spinal cord along most of its length. These nerves make up the peripheral nervous system of which will be the topic of next week’s installment in the series.
Simply stated, the primary function of the spinal cord is the transmission of signals or impulses between the brain and the rest of the body.
A secondary function of the spinal cord is involved with our reflexes. Whenever our bodies experience an external painful stimulus or some kind of dangerous situation, it reacts in a manner designed for self preservation also referred to as the fight or flight response. Even though normal signal impulses travel are very high speeds throughout the nervous system, in times of danger or pain, the spinal cord helps to coordinate and process the reaction response decreasing the reaction time of that part of the body. For example, if you have ever stepped on thorn or hot pavement, you instantly lift your foot up before you have a chance to think about it. This reflex response was coordinated and facilitated by the spinal cord.
Some of the most debilitating injuries are those to the spinal cord. Depending on the severity and location along the spinal cord, injuries can run from just pain and inflammation to paralysis of all the body below the site of the injury.
My pastor’s daughter, Abby, was riding in a van full of teenagers in the mountains in central Arizona when the van hit a pothole and lost control. Abby was thrown from the van and injured. Although she did not break her neck of back, there was enough bruising and damage to her upper spinal cord that it resulted in almost total paralysis from the neck down. She has limited movement in one are, but that is the extent of it. So even severe bruising of the spinal is enough to cause permanent paralysis.
For many years, it seemed that nerve tissue did not heal and regenerate like muscle and bone tissue does. However, research over the past five to ten years has shown some examples of nerve tissue healing, giving hope to the thousands of victims of spinal cord injuries. Some of these researchers that are getting good results are using adult and iPS stem cells, meaning that no embryos are created or destroyed in the process.
Evolutionists want you to believe that the complexity and marvelously designed features of the central nervous system composed of the brain and spinal cord evolved from cells that originally never had any type of nerve cell or tissue. Somehow these cells grew together to become more complex and needed something to coordinate and govern this larger organism, so it evolved the first primitive nerve cells. As the critters evolved larger and more complex, the nerve cells bundled together to form the first primitive brain, and so forth and so on until you get modern man and his brain, spinal cord and miles of nerve fibers that run throughout the body.
The only reason people would believe a tale like this is so that they don’t have to accept the fact that they have a Creator and God who they are accountable to. They find it easier to believe in the fairy tales of evolution that defy the very laws of biology, chemistry and information than to face God.
As we continue on this series, join me in praying for those people that God will open their eyes and remove the plugs from their ears so that they may see and hear the wonders of His Creation and discover the need of a personal Savior in Christ Jesus.
This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. Indeed, in their case the prophecy of Isaiah is fulfilled that says:
“‘You will indeed hear but never understand,
and you will indeed see but never perceive.
For this people’s heart has grown dull,
and with their ears they can barely hear,
and their eyes they have closed,
lest they should see with their eyes
and hear with their ears
and understand with their heart
and turn, and I would heal them.’
When does life begin?
Take a journey from conception to birth with Dr. David Menton, former professor of anatomy at the prestigious Washington University School of Medicine in St. Louis. Dr. Menton provides both a biblical and scientific answer to the question of when life begins.
Taken from one of Dr. Menton’s lectures, this video will reveal the wondrous design of the womb along with the numerous miracles involved along every step of the development of the unborn child.
Following the tragic starvation induced death of Terry Schiavo, Dr. Menton clearly shows the value and sanctity of human life.
With grace and sensitivity Dr. Menton concludes with a salvation message and explanation of the second birth process as described in John 3.
