The knee

The knee forms the connection between the thigh and lower leg. The complex joint is protected from the front by the kneecap, there are stabilizing ligaments and muscles on the side, important nerve tracts, arteries (popliteal artery or arterial artery) and veins (knee-joint vein or

Foot feet

The feet form the lower end of the legs. They are connected to the lower leg via the ankle and are divided from the back to the front into the area of ​​the tarsus, midfoot and toes. Their basic structure forms a large number of bones. These are movably connected to one another by numerous joints, particularly in the area of ​​the toes.

The hand

The lowest section of the human arms is formed by the hands as a gripping organ. They are connected to the forearm via the wrist and are extremely flexible thanks to their special bone structure. From the forearm downwards, the proximal (scaphoid, moon, triangle, pea) and distal carpal bones (large polygonal, small polygonal, scalp, hookbone) form the beginning of the hand.

The poor

The arms form the so-called upper extremities of humans. The arms are divided into three different sections: upper arm, forearm and hand. Between the upper arm and forearm is the elbow joint, which contributes to the enormous mobility of the arms. What is also important here is the special nature of the shoulder joint, which enables movements in almost all directions.

Forearm

The lower section of the arms between the elbow and hand is called the forearm. Its bone structure consists of ulna and spoke, which together with the humerus form the elbow joint at their upper end. The wrist is only a connection between the lower end of the spoke and the carpal bones - the ulna is not involved here.

The thigh

The thigh forms the section of the leg between the hip and knee. First it borders on the groin region in the front view and on the buttocks in the rear view. The base of the bone is the thigh bone (femur or also femur). This is the longest bone in the human body and is exposed to enormous loads every day.

The elbow

The elbow is usually the connection between the upper arm and forearm, which includes both the elbow joint and the surrounding tissue structures. The elbow joint, formed from the lower end of the upper arm bone and the upper ends of the ulna and spoke, makes a significant contribution to the enormous mobility of the arms by not only allowing the arm to bend and stretch, but also to rotate it.

The legs

The legs form the lower extremities of humans and extend from the buttocks to the feet. They are used for locomotion and have to carry the body weight, which can result in considerable stress and increased signs of wear, especially if you are overweight. The large joints (hip joint, knee joint) in particular are often affected here.

The upper arm

The area of ​​the upper extremities (arms) between the shoulder and elbow is defined as the upper arm. Its bone structure only includes the humerus, which is a large tubular bone at the upper end with the bone head in the socket of the shoulder blade and at the lower end forms the elbow joint together with the ulna and spoke.

The lower leg

The section of the leg between the knee and foot is called the lower leg. Its bony base is formed by the shinbone (tibia) and the fibula (fibula), which are connected to each other in the area of ​​the knee by a relatively rigid joint and are in a band-like joint connection to each other below in the area of ​​the ankle.
