The surface of the human body is skin, so it looks young to maintain the whole body skin. There are muscles and bones in the skin. In the head and trunk, skin, muscles and bones enclose two large cavities: cranial cavity and body cavity, which are connected with the spinal canal in the spine, and the brain in the cranial cavity is connected with the spinal cord in the spinal canal; The body cavity is divided into upper and lower cavities by the diaphragm: the upper cavity is called the chest cavity, which contains organs such as heart and lung; The lower part is called abdominal cavity, and the lowest part of abdominal cavity (that is, the part in pelvis) is also called pelvic cavity. There are organs such as stomach, intestine, liver and kidney in abdominal cavity, bladder and rectum in pelvic cavity, ovary and uterus in women.

Skeleton structure is the key to human body structure, which determines the length of human body proportion, the size of body shape and the growth form of each limb in appearance. There are about 206 bones in the human body, which constitute the scaffold of the human body.

Human space medicine can purify the internal space of human body by adjusting the movement and function of energy field in various space parts, provide a good space environment for the radiation and absorption of cells, and at the same time promote and impact various cell groups, activate and improve the vitality of cells, and restore the digestion and absorption function of cells, so as to play and adjust the potential state of human body, and then achieve the purpose of preventing and treating diseases, being healthy and living longer.

"Space medicine" inherits and develops the essence of traditional medicine in China, integrates the cell theory of western medicine and the perfect embodiment of "harmony between man and nature", health preservation and fitness, holistic treatment and intelligence enhancement of traditional Chinese medicine, and is a successful attempt to establish the phenomenological theory of traditional Chinese medicine.

The art of body structure

The human body consists of inorganic matter and organic matter. Inorganic substances are mainly sodium, potassium, phosphorus and water; Organic compounds are mainly sugars, lipids, protein and nucleic acids.

The basic unit of human structure is the cell. There is a non-cellular substance between cells, called intercellular substance.

Cells can be divided into three parts: cell membrane, cytoplasm and nucleus. Cell membrane is mainly composed of protein, lipids and sugars, which can protect cells, maintain the stability inside cells and control the material exchange inside and outside cells. Cytoplasm is the center of cell metabolism, which is mainly composed of water, protein, RNA, enzymes and electrolytes. There are also various organelles suspended in the cytoplasm. The main organelles are mitochondria, endoplasmic reticulum, lysosomes and centrosomes. The nucleus is surrounded by a nuclear membrane, which contains nucleoli and chromatin. Chromatin contains nucleic acids and protein. Nucleic acid is a substance that controls biological inheritance.

Nerve tissue is composed of neurons and glial cells, which is highly sensitive and conductive. Neurons consist of cell bodies, dendrites and axons. Dendrites are short and branched, and their function is to transmit impulses to cell bodies; Axons are very long, with nerve endings at the end, and their function is to transmit the impulses of cell bodies to the outside world.

Muscle tissue consists of muscle cells. Muscle cells have the function of contraction. Muscle tissue can be divided into skeletal muscle, smooth muscle and myocardium according to morphology and function.

Connective tissue consists of cells, intercellular substance and fibers. It is characterized by loose cell distribution and more intercellular substances. Connective tissue mainly includes loose connective tissue, dense connective tissue, adipose tissue, cartilage, bone, blood and lymph. They have the functions of support, connection, nutrition, defense and repair respectively.
