The shoulder girdle is composed of the clavicle and the scapula, which articulates with the proximal humerus of the upper limb. Four joints are present in the shoulder: the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints, and glenohumeral joint.
What are the three joints of the shoulder girdle?
The shoulder girdle consists of three bones (clavicle, scapula, and humerus) and three joints ( sternoclavicular, acromioclavicular, and glenohumeral ) as shown in Fig.
What bones and joints make up the shoulder girdle?
The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle, and the glenohumeral joint.
What bones make up the elbow joint?
The elbow is where the two bones of the forearm – the radius on the thumb side of the arm and the ulna on the pinky finger side – meet the bone of the upper arm — the humerus.
What are girdle bones?
The pelvic girdle is a ring of bones attached to the vertebral column that connects the bones of the lower limbs to the axial skeleton. The pelvic girdle consists of the right and left hip bones. Each hip bone is a large, flattened, and irregularly shaped fusion of three bones: the ilium, ischium, and pubis.
What makes up the pelvic girdle?
In discussing the pelvis, a distinction can be made between the “pelvic spine” and the “pelvic girdle.” The pelvic girdle, also known as the os coxae, Latin for “bone of the hip,” consists of the fused bones identified individually as the ilium, ischium, and pubis.
What are shoulder girdle muscles?
The five muscles that comprise the function of the shoulder girdle are the trapezius muscle (upper, middle, and lower), levator scapulae muscle, rhomboid muscles (major and minor), serratus anterior muscle, and pectoralis minor muscle.
Which bones make up the pectoral girdle and free upper limb?
The bones that attach each upper limb to the axial skeleton form the pectoral girdle (shoulder girdle). This consists of two bones, the scapula and clavicle ((Figure)).
What is pectoral girdle and pelvic girdle?
The pectoral girdle stabilizes the upper limbs on the thorax and allows a range of mobility at the shoulder. The pelvic girdle transfers upper body weight to the lower limbs by articulating with the spine.
Is the sternum part of the shoulder girdle?
The pectoral girdle consists of the clavicle and the scapula, which serve to attach the upper limb to the sternum of the axial skeleton. The scapula (shoulder blade) lies on the posterior aspect of the shoulder.
Which three bones make the hinge joint in the elbow?
Anatomy of the Elbow. The elbow is a complex joint formed by the articulation of three bones – the humerus, radius and ulna.
What is the bone above the elbow called?
The Humerus (upper arm bone) forms the upper portion of the joint. The lower end of the humerus divides in to two bony protrusions known as the medial and lateral epicondyles which can be felt on either side of the elbow joint.
What’s the elbow bone called?
Humerus: This long bone extends from the shoulder socket and joins the radius and ulna to form the elbow. Radius: This forearm bone runs from the elbow to the thumb side of the wrist. Ulna: This forearm bone runs from the elbow to the “pinkie” side of the wrist.
