Muscle cells are also called myocytes. These are the cells that produce muscle tissues. In the human body, there are 3 different types of muscle cells;
one is cardiac muscle, second is skeletal muscle and the third one is smooth muscle. Cardiac and skeletal muscles are also known as muscle fibers because of their shapes.
Their shapes are long and are fibrous. Striated muscles also known as skeletal muscles are of great importance among all. Our skin is the biggest organ of our body having a surface. The muscular system in the human body is not match-able when it comes to mass. Our muscles contain 50% of bodyweight depending upon gender and age.
Each muscle cell has different functionality in different human organs. Muscles are also different in terms of color, shape, form, and properties and in this way, they can be organized. We will represent the basic level of classification of muscle cells in the following paragraphs.
Cardiac Muscle Cells:
Cardiac make a branched cellular network in the whole heart. Their connectivity is end to end through intercalated disks that are structured into different layers of myocardial tissues. These tissues are wrapped and surround the chambers of the heart. The components of cardiac muscle cells help in excitation and recovery of the metabolic processes. The plasma membrane is the major component of doing all this.
Cardiac is striated because of the arrangement of contractile proteins. The intercalated disks are structured at the right angle of muscle fibers. They are formed like zigzag bands that cut across the muscle fiber. At the intercellular spaces, there are supporting tissues that have networks of capillaries. The larger amount of capillaries make sure that there is adequate delivery of oxygen and nutrients to fulfill the metabolic demands of cardiac muscle cells.
Cardiac health somehow also depends on cardiac muscles. There are different effective ways to make your cardiac muscle cells strong. Some of them are explained below.
Aerobic exercises enhance your blood circulation in the body and lower your blood pressure level. It helps in improving your overall cardiac output. These exercises lower the risk type 2 diabetes and control it if you already have. Aerobic exercise improves your overall blood glucose level and makes your heart pumps better and regularly.
Cycling, running, swimming, sports, jumping rope, brisk walking and tennis are all the best aerobic exercises. Some doctors recommend at least 150 minutes per week of activity for healthy life. You can have these exercises at least 30 minutes a day or five days a week.
Smooth Muscles Cells:
Smooth are tissues that are found in the walls of some hollow organs of the human body like stomach, uterus, and intestines. Arteries and veins are also made of smooth muscles cells. These are involuntary and non-striated muscle cells. Smooth muscle cells are also found in the tracts of respiratory, urinary and reproductive systems. Change in the size of iris and lens shape is due to smooth muscle cells. Our skin also has smooth muscle cells that allow hair to grow in the response to fear or hot or cold temperatures.
Fibers in smooth muscles are in groups in branching bundles. Opposite to skeletal muscle cells, these bundles are not parallel and in ordered form rather they lie in a complex system. So that cells may become much stronger. Our body is made of 640 muscles approximately and without muscles, we cannot move. Muscle cells keep the skeleton upright and help in movement. Muscles play a vital role in our body’s chemical processes. They produce heat and keep the processes aligned and going.
Smooth is based on visceral muscle tissue and is under the control of the nervous system. That means you cannot control the movement of these muscles actively and intentionally. Like you say that you want to control your heart to pump. You cannot do that because that movement is not in your control. You say you don’t want your hair to grow in fear, you cannot control this movement because this is because of smooth muscles.
They are responsible for circulatory system regulation. They owe the regulation of metabolism and digestion that is done through the stomach and intestines and the regulation of sexual function. Smooth muscles don’t get fatigued and they also cannot be trained and built like other muscles of the body. You can increase their working capacity and improve them but you cannot build them.
Skeletal Muscle Cells:
Skeletal muscles include around 400 different muscle cells. It involves the majority of the whole muscular system in the human body. Skeletal muscles also include tongue, larynx and diaphragm but they are not included in the movement and stability of skeleton muscles and extremities. Striated muscles can be controlled intentionally while smooth muscle cells cannot be controlled. They can be trained and stimulated. These muscle cells can tense up and get fatigued and grow.
The smallest muscle in our body is inside the ear and is very active when we hear loud noises. Its name is musculus stapedius. Its length is only a few millimeters and is very thin.
