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 only of the skeleton, but also of 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.

There are several kinds of bones in the human skeleton. 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: bones of the foot and hand.

3. Flat: skull bones and scapula.

The bone is covered from above with a dense membrane called the periosteum. Due to it, the growth of bones, their nutrition, 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 in the human body are 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. The facial area includes various small and large bones (nasal and zygomatic bones, lower and upper jaws). They are immovably connected to each other, except the lower jaw.

Now consider how many bones in the human body belong 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 divisions: a hand, a forearm and a 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 feet, legs and thighs. The thigh consists of the femur, which is the largest in the whole body. The shin is made of 2 tibia bones, and the foot consists of several small bones, the largest of which is the calcaneus. The lower extremities are attached to the trunk due to pelvic bones.

Despite the data given in the article, it is still impossible to say unequivocally how many bones are 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.
