ANATOMY OF HUMAN BODY
ANATOMY OF THE HUMAN BODY.
About human body :
Explore the intricate anatomy of the human body. Our comprehensive resources provide detailed insights into structures, functions, and systems for all learners.
Generally we can divide the human body and related knowledge into two parts.
One, Anatomy or Physiology or Physiology. By studying anatomy, we can learn about different organs, structures and parts of the body, size, structure, function, relationship with each other, location of bones etc.

And by studying anatomy, we can learn about the workings and methods of various glands, tissues and organs of the human body.
From both these sciences we can gain complete and holistic knowledge of the human body.
The major parts and organs of the human body are as follows:
(1) Cells(2) Fiber or tissue(3) Bones(4) Cartilage(5) Bones and joints(6) Muscles(7) Blood(4) Arteries or blood vessels(9) veins(10) Nerves(11) Skin(12) Gland(13) Fat(14) Hair (15) Nails(16) Follicles(17) Andhra(18) Spine(19) Brain(20) Liver(21) Gallbladder(22) Spleen(23) Stomach or Stomach(24) Clome gland or pancreas(25) Heart(26) Bones of upper and lower limbs(27) Genital system etc.
Cell an organism is made up of different types of cells.
Whether it is an animal body or a human body, this is the cell at the root.
Since every cell is living, that is, alive, every cell has to constantly collect its food and nutrients from the surrounding medium from wherever it is.
Metabolism or chemical and metabolic processes are going on in every cell naturally.
Again, two very important elements are at the root of the development of this cell. Protoplasm and Nucleus .
Cell.
formation is impossible without these two elements. Protoplasm is a liquid sticky substance. This most important component of the human body is the lifeblood of every living cell.The nucleus is located in the center of this protoplasm surrounded by a transparent and thin membrane. Such a thin coating is also present on the outer surface of the protoplasm. This coat or thin membrane surrounds the protoplasm like a wall. It is called Cell membrane.
To put it more simply, it is called Cell well. Similarly, the membrane that surrounds the nucleus is called the nucleus membraneThe chemical composition of the protoplasm or nucleus is as complex as it is mysterious. Interestingly, the nucleus is located within the protoplasm
The nucleus also contains a type of fluid. Although there are some differences between the two in structure and shape. Fats, proteins, carbohydrates, inorganic salts and water play a very important role in the structure of a cell. We can observe these elements by chemically analyzing a cell.These cells are further divided into several divisions or classes. Several cells work together to form a fiber or tissue. Like cells, the contribution of these tissues to the overall structure of the human body is essential. Because the human body is made up of these fibers or tissues.
Tissue .
structures are made of bamboo to build clay idols. When the structure is built, it is tied with straw.
And the use of twine rope is essential to tie bundi. In the human body, fibers act as this thread. which may be called parentheses. These tantras keep all the organs, bones and even muscles of the body properly and in the right place. That's why body parts or devices don't fall off.
As mentioned when discussing cells, many cells come together to form a tissue. These tissues are of different types according to function and role.
All the tissues that bind the bone to the bone are called ligaments. The tissues that bind the bones to the muscles are called tendons. Besides, there are some theories like thin fiber.
They can be called thin theory (Fibrous Tissue). Comparatively, the muscular ligament is the strongest.
Apart from these there are several tissues which have different roles. One type of theory covers the various internal and external parts or organs of the body, such as the secretory glands, blood, skin, lymphatic vessels, kidneys, heart, peritoneum, gall cells, etc. These are called Epithelial Tissue. Different tissues are formed with different types of cells according to different needs. Mouth cavity, trachea, stomach etc. which are covered with the special membrane are also formed by the above epithelial tissue. So are cylinder epithelium, squamous epithelium.Epithelial Tissue: As mentioned earlier, this type of tissue or outer tissue forms the outer part of the body and the covering part of various internal devices. However, the structure or shape of all of them and everywhere is not the same. Their composition is different according to the need and according to the field. As such, they are different There is also a variety of naming. For example, columnar or cylinder epithelium, squamous epithelium etc.Usually they are adjacent to each other. It is sometimes made up of many cells or cells arranged side by side like fish scales.
Connective Tissue:
All the tissues that connect the skin on the body and the different parts inside the body are called connective tissue. On the one hand, these tissues help to keep the internal organs of the body organized and coordinated, and also maintain the contact between bones and cartilage with the skin etc. at all times. Such as braces. Its function is to connect bone with bone. English name is Ligament. Again, all the tissues that bind the bone to the bone are called tendons. But wherever the tissues are, they are undoubtedly the main building blocks of the body.
involuntary muscle,
side by side showing the location of the nucleus within a muscle fiber and the shape of the fiber.Muscular tissue: Although the location and role of these tissues are independent, they are closely related to connective tissue.
Many filamentous red muscle cells join together to form a single muscle.
They are located side by side. It should be noted that muscles are generally of two types.
Voluntary or Striped Muscle and Involuntary or Unstriped Muscle. Almost all muscles that are scarred fall into voluntary muscles. The main difference between the two types of muscles is control. With voluntary muscles we can control certain parts of the body at will.
Such as neck, shoulders, hands, feet, facial muscles etc.
And all the muscles that are not under our control, i.e.
those that we cannot contract and expand at will, are involuntary muscles.
For example, trachea, esophagus, urethra, blood vessels, stomach, gallbladder, bile ducts etc.
They act like themselves. No one is in control. There are some muscles, which are found only in the heart, called cardiac muscles.
Nervous Tissue:
These tissues are made up of narrow nerve cells. These cells are interconnected. The covering over them is called neurolema. Such tissues sometimes form longitudinally solitary slender nerve fibers. Many nerve fibers are combined to form a thick nerve or Thick Nerve, it is also called Nerve Trunk.
Nerve's role is more like that of a messenger. They help to convey a certain feeling to the right place at the right time. For example, when a pin falls on the sole of the foot, its sensation is immediately transmitted to this nerve or nerve in the brain. According to the work, this nerve can be divided into two parts - Sensory Nerve and Motor Nerve. It is the work of the sensory nerves to convey all the sensations outside the body to the brain or nerve center, and the work of the motor nerves is slightly the opposite. Takes instructions from the brain and conveys them to the necessary organs or organs of the body and the organs work accordingly. Like a mosquito sitting on the tip of a toe, the brain senses (through the eyes) and instructs the nerve to move to that particular spot. As a result, it became possible to move the finger and the leg fly flew away.
In addition, there are some nerds scattered throughout the body who act on their own without waiting for anyone to direct or control them. Doctors have named this type of nerve Autonomic Nerve.
