The scapula along with the clavicle and humerus make up the shoulder.

. Serratus anterior also rotates the scapula by pulling its inferior angle laterally. The movement of the clavicles increases the mobility of the shoulder joints beyond what would be possible with only ball-and-socket joints allowing the arm to move in a large circle. Additionally due to the location of the scapula on the axilla there are many lymph nodes and lymph networks in this area which assist with fluid drainage and balance within the body.

The superior region supports the arm and elevates and rotates the scapula the intermediate region retracts the scapula and the inferior region rotates and depresses the scapula. The clavicles function as struts to anchor the arms to the trunk while permitting the movement of the scapulae and shoulder joints relative to the trunk. The scapula is a flat bone that is shaped somewhat like a triangle.

The muscle pulls the scapula in an anterolateral direction along the thoracic wall. Two important arteries the axillary artery and the subclavian artery run anterior to the scapula and posterior to the clavicle. It attaches the upper limb to the body trunk and is formed by two bones.

Scapula and Yoga. The collarbone is a large doubly curved long bone that connects the arm to the trunk of the body. The scapula is also part of the pectoral girdle and thus plays an important role in anchoring the upper limb to the body.

The scapula is commonly called the shoulder blade and is a flat triangular bone. Serratus anterior is important in attaching the scapula to the thoracic wall. The upper limb is attached to the back of the trunk by five muscles the trapezius and the latissimus dorsi which are attached to the scapula and to the humerus and cover nearly all the back from the occiput to the ilium.

The scapula is located on the posterior side of the shoulder. Skeletal muscles prominate ridge that runs across the posterior surface of the scapula scapular spine only joint between upper appendage and axial skeleton involves which bones. The muscles that control the.

The shoulder girdle is attached to the trunk at both the cervical and lumbar regions. Its functions are to protect the head and neck while lifting the arm toward the face. Its inserted on the coracoid process.

In doing so the scapula connects the upper limb to the trunk. The trapezius originates from the skull and spine of the upper back and neck. It also assists in breathing by moving the ribs up and down.

It functions by raising the. It is a triangular flat bone which serves as a site for attachment for many 17. Together with the clavicle and the sternum the scapula forms part of the shoulder girdle which attaches the appendicular skeleton the limbs to the axial skeleton the trunk.

The ligaments of the scapula are predominantly named based on the two points they attach. The scapula is at the back of the trunk you can quickly feel it if. The clavicle bone also called collarbone is a small curved bone that sits horizontally on each side of the superior thorax.

The clavicle is a modified long bone and is subcutaneous throughout its position. They are the transverse scapular ligament discussed earlier coracoacromial ligament coracoclavicular ligament coracohumeral ligament glenohumeral ligaments and acromioclavicular ligament. It consists of the Shoulder girdle Skeleton of the upper limb Pelvic girdle and Skeleton of the lower limb.

It is surrounded by muscles on both its anterior deep and posterior superficial sides and thus does not articulate with the ribs of the thoracic cage. The muscles of the shoulder either connect the scapula and clavicle to the trunk or connect the clavicle scapula and body wall to the proximal top end of the humerus. It articulates with the humerus at the glenohumeral joint and with the clavicle at the acromioclavicular joint.

It attaches to the scapula laterally at the acromioclavicular joint and the sternum breastbone medially at the sternoclavicular joint. Medially it articulates with the manubrium of the sternum breastbone at the sternoclavicular joint. The point of origin is the second to the eighth ribs and the point of insertion is the scapula.

The muscle is innervated by the long thoracic nerve C5-C7 which is a branch of the brachial plexus. Clavical and sternum primary function of the pectoral girdle position shoulder joint and provide base for arm movement. Pectoralis minor produces depression of the scapula.

The shoulder girdle is involved in many other movements of the body such as shaking hands throwing a ball and singing. The trapezius levator scapulae and rhomboids originate from the base of the skull andor spine and connect the scapula and clavicle to the trunk of the body. Underneath the trapezius are the two rhomboid muscles and the levator anguli scapulae.

What attaches the scapula to the trunk of the body. The scapula is also known as the shoulder blade. The function of the scapula is to provide movement and stabilization of the arm at the shoulder by attaching it to the trunk of the body known as the thorax.

It is the skeleton of appendages of the human body. Last on the list of muscles passing from the trunk to the scapula is the one on the front. Located directly above the first rib it acts as a strut to keep the scapula in place so that the arm can hang freely.
