Structure consisting of several bones, protecting the brain. It consists of the cranial skull (frontal bone, parietal bones, occipital bone, temporal bones, sphenoid bone, ethmoid bone) and facial skull (nasal bones, lacrimal bones, inferior nasal concha, maxillary bones, palatine bones, zygomatic bones, mandible). Interesting fact: The skull is made of several bones connected by sutures, which are zigzag lines. These sutures act as natural 'shock absorbers' for the head, absorbing impacts and protecting the brain.

Column of vertebrae that supports the body and protects the spinal cord. It consists of: Cervical - 7 cervical vertebrae Thoracic - 12 thoracic vertebrae Lumbar - 5 lumbar vertebrae Sacral - 5 sacral vertebrae Coccygeal - 3-5 coccygeal vertebrae Interesting fact: The human spine consists of 33-34 vertebrae, including the sacral and coccygeal vertebrae, which are fused.

Consists of three components: the sternum, ribs, and thoracic vertebrae. Protects the chest organs such as the heart and lungs. The sternum is a spongy bone, consisting of the manubrium, body, and xiphoid process. The ribs and clavicle attach to the sternum. The sternum has jugular and clavicular notches at the manubrium. Humans have 12 pairs of ribs. Each rib consists of a bony and cartilaginous part. The cartilaginous part is formed by hyaline cartilage. The bony part of the rib has a head, neck, and tubercle. A groove runs along the lower edge of the rib, where the intercostal vessels and nerves lie. The ribs are connected by joints to the thoracic vertebrae. Interesting fact: The number of ribs in a human can vary; most have 12 pairs, but some are born with a 13th pair or other rib anomalies, usually detected on X-rays and rarely affecting health.

Pelvic bone structure at the lower part of the torso, to which the legs are attached. This anatomical formation consists of two pelvic bones, sacrum, and coccyx. The pelvis has two sections: the greater pelvis and the lesser pelvis. Interesting fact: Pelvic bones are wider in women to provide space for childbirth.

This is a tubular bone. At the proximal epiphysis, there are the head, greater and lesser tubercles, anatomical and surgical necks. The diaphysis has a deltoid tuberosity and a radial nerve groove. At the distal epiphysis, there are medial and lateral epicondyles, ulnar and coronoid fossae. Interesting fact: The humerus is one of the longest and strongest bones in the human body.

This is a tubular bone, located on the forearm medially in a pronated position and laterally in a supinated position. The proximal epiphysis has a head. The distal epiphysis has a styloid process and a joint surface for connection with the wrist bones. Interesting fact: The radius rotates around another forearm bone - the ulna, allowing the wrist to rotate.

This is one of the two long bones on the forearm. It is located on the inner side of the forearm when looking at the hand palm up. The upper part of the ulna consists of the olecranon (elbow process), coronoid process, and trochlear notch. The lower part of the ulna consists of the head of the ulna and the styloid process. Interesting fact: The ulna forms a visible protruding 'elbow' on the back of the hand.

This is the largest and longest tubular bone in the human body. It consists of a diaphysis (body of the bone) and two epiphyses. The proximal epiphysis includes the head, greater and lesser trochanters. The head connects to the body of the bone via the neck. The distal end of the femur is expanded and formed by medial and lateral condyles. Interesting fact: The femur can withstand weight tens of times greater than the human body weight.

The fibula is located laterally (on the outer side) from the tibia. The proximal epiphysis of the fibula has a head, and the distal epiphysis forms the lateral malleolus. Interesting fact: The fibula plays an important role in stabilizing the ankle.

The tibia has a three-sided body shape. The proximal epiphysis of this bone is thickened and includes lateral and medial condyles. On these condyles is a flat upper joint surface, divided by an intercondylar eminence. The distal epiphysis of the tibia contains a lower joint surface for connection with the talus and forms the medial malleolus. Interesting fact: The tibia is the most frequently broken among all the long bones of the body.

The bones of the human foot are divided into three main groups: tarsal (bones of the hindfoot), metatarsal (bones of the midfoot), and phalanges (toe bones). Each group of bones is important for balance, cushioning, and mobility during walking, running, or standing. Interesting fact: The foot contains about 25% of all the bones in the human body. This is due to its complex structure, which includes 26 bones, 33 joints, and over 100 ligaments.

The hand consists of wrist bones, metacarpal bones, and the skeleton of the fingers (phalanges of the hand). The wrist bones consist of short spongy bones arranged in two rows, four in each. The upper row consists of the pisiform, triquetrum, lunate, and scaphoid bones, while the lower row consists of the hook bone, capitate, trapezoid, and trapezium; The metacarpal bones are five short tubular bones. They are differentiated into a base, body, and head. The skeleton of the fingers consists of short tubular bones - phalanges. Each finger, except for the thumb, has three phalanges: proximal, middle, and distal. The thumb has only two phalanges - proximal and distal. Interesting fact: The human hand contains 27 bones, which is a quarter of all the bones in the body. This allows it to have a wide range of movements and precise motor skills.
