The skeleton is the ‘skeleton’ of the body, and the skeleton is divided into cortical bone and medullary bone. So do you know how many bones there are in the body? The following is the total number of bones in the human body sorted out by web editors, hoping to be helpful to you.

Humans have 206 bones. The bones are generally connected to each other by joints and tendons. One of the components of the skeleton is mineralized bone tissue, which has a hard, honeycomb-like three-dimensional structure internally; other tissues include bone marrow, periosteum, nerves, blood vessels, and cartilage. The skeleton of the body serves as a support point for the human body and is part of the body’s musculoskeletal system. The skeleton is a hard human organ that constitutes the internal skeleton of mammals, its function is to promote physical fitness, adapt to and maintain the human body; produce red blood cells and white blood cells; store minerals. The skeleton is composed of various different shapes, with complex nature and external structure, which allows the skeleton to maintain hardness while reducing weight.

The following is part of the composition of the skeleton

The skull: (8 cranial bones) frontal bone, ethmoid bone, sphenoid bone, occipital bone (not paired), parietal bone, temporal bone (15 facial bones) nasal bone, lacrimal bone, maxilla, inferior turbinate, mandible, hyoid bone, vomer (not paired).

The trunk bones: 24 vertebrae, one scapula, 12 pairs of ribs, one coccyx, one sacrum.

The limbs bones: 1 clavicle, 1 cervical bone, 1 humerus, 1 ulna, 1 radius, 8 carpal bones, 5 metacarpal bones, 14 phalanges * 2 (upper limb bones 64), 1 hip bone, 1 femoral head, 1 patella (knee joint), 1 ankle joint, 1 fibula, 7 tarsal bones, 5 sesamoid bones, 14 phalanges * 2 (lower limb bones 62).

Bone nutrition elements

1. Bone ‘Supporter’: Calcium

Human bones are ‘alive’. When calcium intake is insufficient, calcium in the bones will be released into the blood to maintain blood potassium concentration, causing a sharp decrease in bone density, and the bones become more porous, leading to fractures, degenerative changes in osteoarthritis, or rickets in children.

2. Bone ‘Gas Station’: Vitamin D

It can promote the absorption of calcium in the intestines, reduce renal calcium metabolism, and continuously supplement calcium to the bones like a gas station. If vitamin D is deficient, the strength of the bones will decrease, leading to ‘osteomalacia’. Children are prone to maldevelopment of the skull and diaphragm, and are prone to hunchback; pregnant women and the elderly may have reduced bone strength in the lower limbs and pelvis.

3. Bone ‘Concrete’: Protein

22% of the composition of bones is protein, mainly collagen. With protein, human bones can be as hard as concrete, not brittle, and have elasticity, withstanding the impact of external forces. Carbohydrates and active peptides in proteins are beneficial to the absorption of calcium.

If protein intake is insufficient for a long time, not only will the production of new bone be delayed, but it is also easy to cause osteoporosis. Research has found that people who do not like to eat meat and beans and have a long-term protein deficiency are more prone to hip fractures.

7. Bone ‘Cleaner’: Vitamin B12

Vitamin B12 is the only vitamin that contains mineral phosphorus and plays a key role in maintaining bone strength. It acts like a ‘cleaner’, able to remove homocysteine from the blood, protect bones, and prevent osteoporosis and even hip fractures caused by excessive homocysteine.

4. Bone ‘Protector’: Magnesium

60% to 65% of magnesium in the body is stored in the bones. Experts indicate that magnesium plays a key role in the production of new bone. Although the content of magnesium in bones is small, its deficiency can make bones脆 and more prone to fracture.

Long-term magnesium deficiency can also lead to vitamin D deficiency, affecting bone health. Women with low magnesium intake in their diet have lower bone density.

5. Bone ‘Thickener’: Potassium

Every cell in the body contains potassium, and bones are no exception. Its key function is to maintain acid-base balance, participate in oxidative phosphorylation and normal muscle nerve function, which is essential for the growth and metabolism of bones. A study published in the international journal ‘Environmental Nutrition’ also emphasizes that potassium can prevent calcium loss and make bones denser.

6. Bone ‘Preservative’: Vitamin B12

Just as food needs certain preservatives, bones also need the preservative vitamin K to activate a very important protein in the bones – osteocalcin, thereby enhancing the bone’s ability to withstand compression.

Research conducted by Harvard University in the United States shows that if women have a low intake of vitamin K, it will increase the risk of osteoporosis and femoral fractures. Spanish scientific research has found that supplementing with vitamin K can promote the bone health of children and adolescents, and reduce the incidence of arthritis.
