How many bones in the human body total
Many people are interested in how many bones in the human body. We will try to answer this question.
The human musculoskeletal system consists not ofonly from the skeleton, but also from the muscles. With his help, a person makes different movements, and he also protects internal organs from various injuries. The shape of the human body is determined by the skeleton. There are about 210 bones in the body.
In the human skeleton there are several kinds of bones. I would like to consider in more detail how many bones in the human body, and what they are. There are the following types:
1. Long bones: humerus, forearm, thigh and drumstick.
2. Short: the bones of the foot and hand.
3. Flat: bones of the skull and shoulder blades.
The bone is covered from above with a dense shell, whichis called the periosteum. Due to it, bones grow, their nourishment, as well as intergrowth in fractures. Due to the periosteum, the bones grow in width, and in length they grow by dividing the cartilage cells that are located between the body of the bone and its ends.
In general, the skeleton is made up of the skull, the skeleton of the lower and upper extremities and the trunk.
Let us consider in more detail how many bones inthe human body is in each of the components. The skull consists of the facial and brain departments. To the brain department is the skull, which serves to protect the brain from various injuries. The brain department includes: frontal, occipital, 2 parietal and 2 temporal bones. To the facial area are various small and large bones (nasal and zygomatic bones, lower and upper jaw). They are immovably connected to each other, except the lower jaw.
Now consider how many bones in the human bodyrefers to the skeleton of the trunk. It is formed by the spine and thorax. 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 departments, which have the same name as the vertebrae, which they enter.
The thorax, which protects the lungs and the heart from damage, consists of 12 ribs and a breast bone.
The structure of the upper limbs includes three sections: brush, forearm and shoulder. The shoulder is formed by a long humerus, the forearm - elbow and radial bones, and the brush consists of small ossicles. Hands are attached to the body with clavicles and shoulder blades, which form the shoulder girdle.
Lower extremities include the feet, legs andhips. The thigh consists of the femur, which is the largest in the whole body. The drumstick is made of 2 tibia bones, and the foot consists of several small bones, the largest of which is the heel. Lower extremities are attached to the trunk due to pelvic bones.
Despite the data given in the article, allequally can not unequivocally say how many bones in the human skeleton. For example, a newborn has much more than an adult, since small bones split into large ones already in the process of growing a child.
Therefore, a specific figure, reflecting how many bones in the human body, no. Someone indicates the number 200, someone 220.
