How do human bone diseases promote bone growth 1 How many bones does a person have? Skull: cerebral cranium (paired: parietal bone, temporal bone, unpaired: frontal bone, ethmoid bone, sphenoid bone, occipital bone =8 pieces), facial skull (paired: maxilla, palatine bone, cheekbone, tears).
Trunk bone: 24 vertebrae, 1 sternum, 12 pairs of ribs, 1 coccyx, 1 sacrum =5 1 block.
Limb bones: 1 scapula, 1 clavicle, 1 humerus, 1 ulna, 1 radius, 8 carpal bones, 5 metacarpals, 14 phalanx *2 (upper limb bone 64)
1 hip, 1 femur, 1 patella (kneecap), 1 tibia, 1 fibula, 7 tarsal bones, 5 metatarsals, 14 phalanges *2 (lower limb bones)
2 human skeleton structure diagram How many pieces of human skeleton are there? There are 206 bones in the human body, which are divided into three parts: skull, trunk and limbs. Among them, there are 29 skulls, 5 1 trunk bones and 0/26 limbs bones.
Children's bones should actually be 2 1 7 ~ 218, and newborn babies have as many as 305 bones, because children have five sacrums, which will be1block when they grow up. Children's coccyx has 4 ~ 5 pieces, and when they grow up, they also synthesize 1 piece. Children have two ilium, two ischium and two pubis, and when they are adults, they merge into two hip bones. In this way, children have more bones than adults11~12.
Types of human bones: long bone, short bone, flat bone, irregular bone and round bone.
1, long bones-humerus and femur < length to width = very large >
2, short bone-wrist < length to width = very small, almost cubic >.
3, flat bone-scapula < plate >
4. Irregular bone-spinal bone
5. Round bone < seed bone >-patella < usually small, located in the inner layer of joint >
4 human skeleton protection function: skeleton can protect internal organs, such as skull to protect brain; Ribs protect the chest.
Support function: bones form the skeleton and maintain the body posture.
Hematopoietic function: Bone marrow produces blood cells through hematopoiesis in the gap between the bone marrow cavity of long bone and sponge bone.
Storage function: bones store important minerals of the body, such as calcium and phosphorus.
Motor function: bones, skeletal muscles, tendons, ligaments and joints together produce and transmit strength to make the body move.
Most bones can perform all the above functions to some extent, but some bones are only responsible for a few of them.
5 Human skeleton components Bone is composed of organic matter and inorganic matter. Organic matter is mainly protein, which makes bone have certain toughness, while inorganic matter is mainly calcium and phosphorus, which makes bone have certain hardness.
In this way, human bones are composed of a certain proportion of organic matter and inorganic matter, so human bones have both toughness and hardness, but the proportion is different; People at different ages have different proportions of organic matter and inorganic matter in their bones. Take children's and teenagers' bones for example, the content of organic matter is more than inorganic matter, so their bones have higher flexibility and plasticity, while the content of inorganic matter in the bones of the elderly is more than organic matter, so their bones have higher hardness, so they are easy to break.
6 Human Skeletal Diseases Skeleton problems are increasingly showing a trend of younger age. The reason is that people don't pay as much attention to skeletal health as other organs of the body, so they are often easily overlooked. Many people have hidden dangers of skeletal health due to bad lifestyles, lack of exercise and heavy work pressure.
1, rickets
Vitamin D deficiency rickets is a common nutritional deficiency in infants and young children. In the early stage, it is often fidgety, crying, easy to wake up and sweating. Later, bone changes gradually appear, such as delayed closure of the anterior fontanel (normally it should be closed before 1.5 years old) and late teething, which can be as late as 1 year old.
2. Osteoporosis
When it comes to bone problems, many people's first reaction is calcium deficiency and calcium supplement. In fact, bone problems are not only due to calcium deficiency, but also related to many diseases and daily life.
3. Fracture
Bone fracture is a kind of fracture. Xiao Bian learned that although bone fracture belongs to a low degree of fracture, it is still sloppy. If there is a crack in the bone and it is not treated properly, the condition will deteriorate and cause a displaced fracture.
4. Fracture
Fracture refers to the continuous complete or partial fracture of bone structure. More common in children and the elderly, teenagers also occur from time to time. Patients often have fractures of one site, and a few have multiple fractures. After timely and proper treatment, most patients can recover their original functions.
5, hyperosteogeny
Hyperplasia of bone occurs mostly in middle age and above. It is generally believed that due to physical weakness and degeneration after middle age; Standing or walking for a long time and holding in a certain posture for a long time, due to muscle pulling or tearing, bleeding, hematoma organized, forming spiny or lip-like bone hyperplasia.
6. Bone cancer
Bone tumor is a tumor that occurs in bone or its affiliated tissues. There are benign and malignant points. In the early stage of bone cancer, there will be a hard lump on the surface of bone, and there will be pain and swelling of bone and adjacent joints, which will often worsen at night. The severity of pain has nothing to do with activity.
7. Osteomyelitis
Osteomyelitis is an infection and destruction of bone, which can be caused by aerobic or anaerobic bacteria, mycobacteria and fungi. Osteomyelitis often occurs in long bones, feet of diabetic patients or penetrating bone injury caused by trauma or surgery. Can osteomyelitis be cured? What symptoms does osteomyelitis have?
8. Necrosis of femoral head
Femoral head necrosis is a troublesome disease in orthopedic diseases, which will bring great harm to our life and psychology. Correct understanding of femoral head necrosis, understanding of treatment methods and early symptoms will have a good effect on the treatment of femoral head necrosis.
9, sciatica
Sciatic neuralgia refers to the pain in the sciatic nerve pathway and its distribution, that is, the pain in the posterior thigh of hip, the posterolateral calf and the lateral foot. This disease should be cultivated by external use of traditional Chinese medicine. Plaster can promote blood circulation, remove blood stasis, relax muscles and tendons, relieve inflammation and relieve pain, and achieve the goal of treating both the symptoms and root causes.
10, osteoarthritis
Skeleton is a hard organ in the body, whose main function is to coordinate the movement of other organs, support and protect the body; Making red blood cells and white blood cells; Store nutrients, etc. Bone health is an important part of human health. However, many friends, especially elderly friends, are prone to osteoarthritis. It is best to treat osteoarthritis early and recover early, so as not to leave a legacy.
7 How to promote bone growth Most bones in the human body complete the process of bone growth and development through cartilage osteogenesis. With the increase of age, the epiphyseal cartilage continues to proliferate and ossify, which makes the bone thicker, thus the body grows taller and taller, and it is generally not basically shaped until the beginning of puberty.
1, pay attention to diet and supplement trace elements appropriately.
Vitamins A, D, C and minerals such as calcium, iron and phosphorus are important components to promote human growth. Milk, eggs, beans, fish, lean meat and other foods are rich in content.
2. Exercise more and get more sunshine.
Exercise can promote metabolism, accelerate blood circulation, deliver more nutrients to bone tissue, accelerate bone growth and make bone dense.
3. Maintain a good sitting posture and standing posture.
The correct posture of sitting and walking, tables, chairs, beds and other facilities should be suitable for the individual's physical development, otherwise it will easily lead to diseases such as hunchback and rickets.
