Know thyself: The Muscular system continued.
We pointed out that we have 3 types of muscles. Skeletal, cardiac and smooth muscles. Last week we focused on skeletal muscles. Maintaining well-conditioned muscles is necessary for a healthy body. The muscular system helps the body to move by contracting and pulling on the bones. It is this continuous contraction and expansion that facilitates movement of nutrients, helping in digestion and pumping of blood to the rest of the body.
About 700 muscles make up the human frame. Muscles can be grouped into voluntary and involuntary. The voluntary muscles are most plentiful of the three types of muscles and are under direct control of the brain. The non-voluntary muscles are activated by the autonomic nervous system and body hormones. They are not under the conscious control of the brain.
The skeletal muscles are voluntary. They are connected to the brain through the somatic nervous system. The skeletal muscles are responsible for protecting the internal body organs from external harm. The lungs and heart are some beneficiaries of this relationship. In our series know thyself, we unpack what we need to do in caring for the body to avoid conditions that make us seek the services of a hospital. This is the foundation of wellness.
In todays’ article, we unpack another 3 major muscles and how they work to keep us alive.
Cardiac muscles are only found in the heart. They constitute the main tissues of the walls of the heart. The cardiac muscles main function is to contract and relax to pump blood around the body. The Cardiac muscles are involuntary muscles. They are the most active muscles in the human body. They never go to sleep from the time the heart forms in the womb until death. Even when we are asleep the heart muscles remain at work.
We should take good care of the heart muscles to keep away cardiovascular diseases that have become the top killer today. We cannot have wellness without taking good care of the heart. Many of the lifestyle diseases originate from a compromised heart or the arteries. The heart is the central transportation engine. It transports oxygen and nutrients to all the organs and cells in the body. It also carries the waste to the disposal organs like kidneys and the skin. We have to keep working out to strengthen the heart muscles for good health.
Smooth muscles are distributed in the visceral organs of the body. They form the walls of most blood vessels, glands and organs within the body. They are responsible for expanding and contracting to allow blood, nutrients and fluids to enter through the organs at varying rates. They are also involuntary and in control of the autonomic nervous system.
Care of muscles.
Man’s body is designed for activity. According to the story of creation, God created Adam and Eve as hunters and gatherers then placed them in a garden. To gather their 3 meals per day they had to walk across the garden. This gave them good exercise to strengthen the cardiac muscles and make the body inhale adequate oxygen.
The gut muscles.
The gut muscles play an important function like the cardiac muscles. They are responsible for food movement from the mouth all the way to the rectum where food waste is deposited ready for disposal. The gut muscles contract in a movement called peristalsis to push the food only one way, forward. Stomach muscles are the 2nd most active muscles after heart muscles.
They are at work processing all the food we eat. We get energy and nutrients from the food we eat. The three meals we eat for breakfast, lunch and supper are processed by the gut muscles from the mouth, in the stomach, small intestine and on to the colon.
Food takes 3 – 5 hours in the stomach depending on the type of food and how well you chewed it in the mouth. We should chew our food properly to allow quick digestion.
We have many more muscles in the human body. All muscles have the ability to hypertrophy (enlarge) in response to activity. Conversely they will atrophy (waste away) if deprived of activity. It is our duty to keep all muscles working adequately not to atrophy.
Keep it here for more tidbits. Next week we will unpack more of what they did not teach you in school.
This is what we are doing in know thyself series.
