Many people are interested in how many bones are in the human body. Let's try to answer this question.
The human musculoskeletal system consists not only of the skeleton, but also of muscles. With its help, a person makes different movements, and it also serves as 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 take a closer look at how many bones are in the human body, and what they are. There are the following types of them:
1. Long bones: humerus, forearm, femur and lower leg.
2. Short: foot and hand bones.
3. Flat: bones of the skull and scapula.
The top of the bone is covered with a dense sheath called the periosteum. Due to it, the growth of bones, their nutrition, as well as fusion in fractures occurs. Thanks to the periosteum, bones grow in width, and in length they grow due to the division of cartilage cells, which are located between the body of the bone and its ends.
In general, the skeleton consists of the skull, the skeleton of the lower and upper limbs and torso.
Let's considerin more detail, how many bones in the human body are in each of the components. The skull consists of the facial and cerebral sections. The brain part includes the cranium, which serves as protection for the brain from various damages. The brain section 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 fixed to each other, except for the lower jaw.
Now consider how many bones in the human body belong to the torso skeleton. 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 they include.
The ribcage, which protects the lungs and heart from damage, consists of 12 ribs and the sternum.
The structure of the upper limbs includes three sections: hand, forearm and shoulder. The shoulder is formed by the long humerus, the forearm by the ulna and radius, and the hand is made up of small bones. The arms are attached to the body with the help of the clavicles and shoulder blades, which form the shoulder girdle.
The lower limbs include the feet, shins and thighs. The thigh consists of the femur, which is the largest in the entire body. The lower leg is made up of 2 tibia bones, and the foot is made up of several small bones, the largest of which isheel. The lower limbs are attached to the body by the pelvic bones.
Despite the data given in the article, it is still impossible to unambiguously say how many bones are in the human skeleton. For example, a newborn has much more of them than an adult, since small bones grow together into large ones already in the process of a child's growth.
Therefore, there is no specific figure that reflects how many bones are in the human body. Someone indicates the number 200, someone 220.
