The humeral head is a part of the upper arm bone, located at the distal end of the humerus and connected with the humeral condyle. It is one of the important bones of human upper limbs, and can form upper limb bones together with radius and ulna. The center of the humeral head is a fossa, which is called the humeral head fossa. Its main function is to receive the head of ulna, form the condyle joint of ulna, and form elbow joint with humeral condyle and humeral capitulum.

The humeral head also has many important physiological functions. It is the starting point and node of many muscles, including biceps brachii, triceps brachii, teres, pronator and supinator. The movement of these muscles can make the upper arm bend, stretch and rotate. In addition, the humeral head can also transport blood and nutrients, and it is a key bone part to treat many diseases.

Because the humeral head is a part of human skeleton, we should keep healthy in our daily life and avoid orthopedic diseases. Some common diseases, such as ischemic necrosis of humeral head, are caused by insufficient blood supply; However, diseases such as fractures and dislocations need timely treatment. In addition, in some sports and working environments, the risk of humeral head injury is high, so we should pay attention to prevention and use appropriate protective measures.
