Many people are interested in how many bones are in the human body. Try to answer this question.
The musculoskeletal system of a person consists not only of the skeleton, but also of the muscles. With his help, a person makes various movements, and he also serves as a protection for internal organs from various injuries. The shape of the human body is determined by the skeleton. There are about 210 bones in the body.
There are several types of bones in the human skeleton. I would like to consider in more detail how many bones are in the human body, and what they are. The following types are distinguished:
1. Long bones: humerus, forearm, femur and lower leg.
2. Short: foot bones and hands.
3. Flat: bones of the skull and shoulder blades.
The bone on top is covered with a dense membrane called the periosteum. Due to it, bone growth occurs, their nutrition, as well as fusion during fractures. Thanks to the periosteum, the bones grow in width, and in length they grow due to the division of cartilage cells that are located between the body of the bone and its ends.
In general, the skeleton is made up of the skull, skeleton of the lower and upper limbs and trunk.
Let us consider in more detail how many bones in the human body are in each of the components. The skull consists of the facial and brain departments. The cerebral section includes the cranium, which serves as a defense to the brain from various injuries. The brain includes: frontal, occipital, 2 parietal and 2 temporal bones. The facial section includes various small and large bones (nasal and zygomatic bones, lower and upper jaw). They are motionlessly connected to each other, except for the lower jaw.
Now consider how many bones in the human body belong to the skeleton of the body. It is formed by the spine and chest. The spine consists of 4-5 coccygeal, 5 sacral and lumbar, 12 thoracic and 7 cervical vertebrae. Due to this, the spine is divided into 5 sections, which have the same name as the vertebrae that enter them.
The chest, which serves as a protection for the lungs and heart from damage, consists of 12 ribs and the sternum.
The structure of the upper limbs includes three departments: hand, forearm and shoulder. The shoulder is formed by a long humerus, the forearm by the ulnar and radial bones, and the hand consists of small bones. Hands are attached to the body with clavicles and shoulder blades that form the shoulder girdle.
The lower limbs include the feet, lower legs, and thighs. The thigh consists of the thigh bone, which is the largest in the whole body. The tibia consists of 2 tibia bones, and the foot consists of several small bones, the largest of which is the calcaneus. The lower limbs are attached to the body due to the pelvic bones.
Despite the data presented in the article, it is still impossible to say unequivocally how many bones are in the human skeleton. For example, in a newborn they are much larger than in an adult, since small bones grow together in large ones already in the process of the child’s growth.
Therefore, there is no specific figure reflecting how many bones are in the human body. Someone indicates the number 200, someone 220.
