The shoulder is the segment of the upper limb between the shoulder and elbow joints. It consists of one long tubular bone - the humerus (humerus).
The humerus connects to the scapula at the shoulder joint, forming a movable joint that allows movement of the arm. At the top of the humerus there is a rounded head, which forms a joint with the glenoid cavity on the scapula.
At the bottom of the humerus there are condyles that form the elbow joint with the bones of the forearm - the ulna and radius. The elbow joint is also movable and allows you to bend and extend the arm at the elbow.
The main muscles located in the shoulder area: biceps brachii, triceps brachii, brachioradialis, brachialis. These muscles provide movement in the shoulder and elbow joints.
Thus, the shoulder plays an important role in the mobility and function of the upper limb.
Shoulder (lat. brachium) is a segment of the human upper limb between the shoulder joint and the elbow. In Latin, the plural of the word "shoulder" is brachia.
The shoulder is one of the largest bones in our body. It consists of three bones: the clavicle, the scapula and the humerus. The collarbone and scapula are connected by the acromioclavicular and scapuloclavicular joints, and the shoulder joint is connected to the scapula by the acromioclavicular joint. At the junction of the clavicle and the scapula there is an articular process called the acromion. It helps keep the shoulder in place while moving.
On the top of the shoulder there are muscles that are responsible for its movement. They help us raise, lower, rotate and bend our arms. One of the most important muscles in the shoulder is the biceps, which is responsible for bending the arm at the elbow. There are also muscles in the shoulder that help us hold objects in our hands, such as the triceps and deltoids.
Overall, the shoulder is a very important part of our body that helps us perform many different movements.
The shoulder is one of the key elements of the upper limb. It plays an important role in performing various actions and allows us to move our arms, legs, head and other parts of the body in different directions. In addition, the shoulder contains many nerve endings and blood vessels that are responsible for transmitting information and nutrition to various organs of the upper limb.
The shoulders are made up of several muscles and ligaments that allow
