shoulder The shoulder is the joint that connects the arm with the body, or the part of body that includes this joint and the muscles up to the base of the neck. An example of a shoulder is where a person hangs the strap on a purse. Shoulder is defined as to be weighed down, troubled or burdened by something. An example of shoulder are polar bears being negatively affected by the effects of global climate change; to shoulder the effects. the joint connecting the arm or forelimb with the body.

Shoulder Anatomy The shoulder is one of the most sophisticated and complicated joints of the body: 1  It has the greatest range of motion of any joint in the body with complete global movement allowing you to position the hand anywhere in space.

Shoulder Instability Normally, the shoulder has a wide range of motion, making it the most mobile joint in the body. Because of this flexibility, however, it is not very stable and is easily injured. The shoulder is made up of 2 main bones: the end of upper arm bone (humerus) and the shoulder blade (scapula). The end of the humerus is round, and it fits into a socket in the scapula. Surrounding the shoulder is a bag of muscles and ligaments. Ligaments connect the bones of the shoulders, and tendons connect the bones to surrounding muscle.

Anatomy of the Shoulder 1 The acromioclavicular joint connects the upper part of the shoulder blade (the acromion) to the collarbone. 2  The glenohumeral joint, also known as the shoulder joint, is a ball-and-socket joint that connects the upper arm to the shoulder blade.he rotator cuff is made up of four muscles and their tendons, which act to hold the upper arm (humerus) to the socket of the shoulder (glenoid fossa). The rotator cuff also provides mobility and strength to the shoulder joint.

Anatomy of the Shoulder The joint cavity is cushioned by articular cartilage covering the head of the humerus and face of the glenoid. The scapula extends up and around the shoulder joint at the rear to form a roof called the acromion, and around the shoulder joint at the front to form the coracoid process.

Bones & Joints of the Shoulder Bones & Joints of the Shoulder. The bones of the shoulder consist of the humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collar bone). The clavicle is the only bony attachment between the trunk and the upper limb. It forms the front portion of the shoulder girdle and is palpable along its entire length with a gentle S-shaped contour.The clavicle articulates at one end with the sternum (chest bone) and with the acromion of the scapula at the other.

Shoulder Anatomy Bones and Joints. The bones of the shoulder are the humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collar bone). The roof of the shoulder is formedby a part of the scapula called the acromion. There are actually four joints that make up the shoulder.

ICD-10 Diagnosis Code M25.519 Your shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). Your shoulders are the most movable joints in your body. They can also be unstable because the ball of the upper arm is larger than the shoulder socket that holds it. To remain in a stable or normal position, the shoulder must be anchored by muscles, tendons, and ligaments.

Picture of the Shoulder The shoulder is one of the largest and most complex joints in the body. The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. Other important bones in the shoulder include: The acromion is a bony projection off the scapula.

Shoulder For other uses, see Shoulder (disambiguation). The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints.

Description Anterior view of the left shoulder and acromioclavicular joints, and proper scapular ligaments. The glenohumeral (GH) joint is a true synovial ball-and-socket style diarthroidal joint that is responsible for connecting the upper extremity to the trunk.It is one of four joints that comprise the shoulder complex.This joint is formed from the combination of the humeral head and the glenoid fossa of the scapula.ogether, the joint capsule and the ligaments of the GH joint work to provide a passive restraint to keep the humeral head in contact with the glenoid fossa.

Shoulder The muscles and joints of the shoulder allow it to move through a remarkable range of motion, making it one of the most mobile joints in the human body. The shoulder can abduct, adduct, rotate, be raised in front of and behind the torso and move through a full 360° in the sagittal plane.

Shoulder The shoulder joint also known as the glenohumeral joint, is the major joint of the shoulder, but can more broadly include the acromioclavicular joint. In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, the head sitting in the glenoid cavity.he joints of the shoulder are the shoulder joint (or glenohumeral joint), and the acromioclavicular joint. Another joint in the shoulder is the sternoclavicular joint that articulates with the sternum and clavicle.

Shoulder Instability and Dislocations The shoulder is a ball and socket joint. The ball is the humeral head or top of the humerus, the long bone of the arm. The socket is called the glenoid and is a process off of the scapula, or shoulder blade. The shoulder socket is relatively flat - more like a golf tee than a coffee cup.

Dislocated Shoulder The shoulder joint is the most mobile joint in the body and allows the arm to move in many directions. This ability to move makes the joint inherently unstable and also makes the shoulder the most often dislocated joint in the body. In the shoulder joint, the head of the humerus (upper arm bone) sits in the glenoid fossa, an extension of the scapula, or shoulder blade.

Shoulder The shoulder joint (also known as the glenohumeral joint) is the main joint of the shoulder. It is a ball and socket joint that allows the arm to rotate in a circular fashion or to hinge out and up away from the body.here are two kinds of cartilage in the joint. The first type is the white hyaline cartilage on the ends of the bones (called articular cartilage) which allows the bones to glide and move on each other. When this type of cartilage starts to wear out (a process called arthritis), the joint becomes painful and stiff.
