The complexity of the human body has been known for centuries. The very fact that its functions are so meticulous in design that scientists (and clergymen alike) finally agree on one thing: it must have been designed by a "higher power" or "God" in his/ her many forms.
And if one must seek to find evidence of the "mastermind" of creation, one can find it in its most exalted example. The human brain (and mind).
As a doctor, when one looks at brain diagrams day in and day out, you will find that the human is truly unique amongst its species, thanks to the brain that it has, that makes it faster, stronger, and powerful than all the other species on Planet Earth.
Just as a kid's site described the "brain", it is indeed the "boss" of the body that controls almost every function that the body carries out either directly or indirectly.
So let's look at some parts such as the brain cerebrum and the brain lobes and what they do, which will give you a clearer picture as to how important your brain is, no matter whether you are a dud as has been determined by your IQ scores.
Lobes of the Brain and their functions
The cerebral cortex is divided into four lobes, namely, the frontal, parietal, temporal and occipital lobe and normally have their own parts to play in the everyday living of a human being.
1. The Frontal Lobe
As obvious as it sounds, this lobe is in front of the brain and is associated with functions such as motor skills, higher lever cognition, reasoning and expressive language. At the back of the frontal lobe lies the motor cortex which is responsible to receive information from the other lobes in the brain while using this information to carry out body movements.
2. Parietal Lobe
This lobe is located in the middle of the brain, and is largely responsible for processing tactile sensory information such pain, touch and pressure. Specifically, the somatosensory cortex which is located in this lobe is responsible for processing the body senses.
3. Temporal Lobe
Located at the bottom part of the brain (above the cerebullum in the figure provided), this lobe also has the primary auditory cortex that is responsible for interpreting sounds and the languages that we use to communicate. The hippocampus is also located in the temporal lobe, and whose function is associated with the formation of memories.
4. Occipital Lobe
This lobe is located at the bottom part of the brain (above the cerebellum as show in the figure provided above) and functions in processing visual stimuli and related information. In particular, the primary visual cortex which is located in the occipital lobe, receives and interprets information from the retinas of the eyes.
And while the debate rages on whether man evolved from monkeys or not, the erstwhile religion vs. science debate can only tell you how evolved this part of the human body truly is.
While we do have Darwin to thank for, in devising the theory of evolution, one cannot help but accept that the complexities of the human body (and in this case, the 'pia mater') could have only been fashioned by a little more than just the processes of Mother Nature.
