10 Interesting Scientific Facts About Human Body and Mind

human body and mind

The human body – is a highly complex machine, an apparatus of intricate, interlocking systems in which millions of vital processes take place. But despite this complexity its mechanism function with inimitable efficiency and precision, and its basic structure is relatively uncomplicated. 

While our understanding and knowledge of how the human body and the mind work is reasonably advanced, the way in which they interact to produce the “person personality” remains an unsolved puzzle.

 

Human Body and Mind

To help us better understand the mind-body connection, here are 10 interesting scientific facts about the Human body and mind:

10. Human Body Cells

The human body’s healthy and proper functioning depends on the close and efficient interaction of the more than 50,000 million cells that contribute to the interaction of the six major systems of the human body, which are Digestion, Skin and hair, Heart and blood, Nerves and brain, Muscles and all important Skeleton.

9. Human Skin

The Human Skin is the first line of defense and acts also as an organ of excretion and water regulation. Not only it protects the body from many potentially dangerous chemical, physical and biological substances, but also enable the body to exist in dry air or be immersed in fresh or salt water.

8. The All-Important Nerve Cells (Motor Neurons)

The motor cells controlling muscle movement lie deep within the spinal cord. These all-important cells provide the final pathway for impulses arising in the voluntary motor area of the brain. It these that are destroyed by poliovirus. When it multiplies in the nervous system, the virus destroys nerve cells (motor neurons) which activate skeletal muscles.

7. The Importance of Villi and Small Intestine

The small intestine is the portion of the digestive tract that connects the stomach and the large intestine. The small intestine contains small finger-like projections of tissue called villi which increase the surface area of the intestine and contain specialized cells that transport substances into the bloodstream.

Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be the more efficient absorption of fatty acids and glycerol into the bloodstream.

6. Voluntary muscle in the Human Body

Voluntary muscles are one of three types of muscle in the body; along with the other two types – smooth and cardiac muscles. There are more than 600 muscles in the body, and each falls into one of these categories. Smooth muscles are involuntary whereas cardiac muscles make up the muscles in the heart.

The voluntary muscles are controllable by your brain and these are the muscles you use to perform activities. The Voluntary muscle consists of bundles of fibers. These are divided into bands, which appear as dark lines under a microscope. They contain actin and myosin, two important contractile proteins.

5. Human Brain

As we grow older, we are unable to remember new things. According to the researchers in the US, it is because the brain is unable to filter and remove old memories which prevent it from absorbing new ideas.

Moreover, the human brain has the capacity to generate approximately 23 watts of power when awake. Messages from the human brain travel along nerves at up to 200 miles an hour (322 km/h).

4. Femur Bone

By most measures, the femur is the strongest and also the longest bone in the human body. It can support 30 times the weight of a person’s body. Ounce for ounce, that’s stronger than steel. The femur is the only bone in the thigh.

All of the body’s weight is supported by the femurs during many activities, such as running, jumping, walking, and standing.

3. Gluteus Maximus

The gluteus maximus is the body’s largest muscle. Its major action is the extension of the thigh, as in rising from a sitting position, running, or climbing. It also rotates the thigh outward.

2. Human DNA

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. If a human being’s DNA were uncoiled, it would stretch 10 billion miles, from Earth to Pluto and back.

1. Creation of Embryo

Only seven weeks after conception, the tiny embryo is clearly visible in the amniotic sac which provides protection. The main internal organs are all formed at this stage – including the heart (that can be distinguishable in black dot color) and the limbs.
