The clavicle also collarbone Latin. Those are all the structures for now.
The coracoclavicular ligament is a very strong structure effectively suspending the weight of the upper limb from the clavicle.
Structure of the clavicle. The clavicle is an elongated S-shaped bone that rests horizontally at the sternum across the upper part of the ribcage and the acromial end of the scapula. This bone is an important part of the skeletal system since it plays an essential role in everyday functional movement serving as the connection between the axial skeleton and the pectoral girdle. The clavicle is a slender bone with an S shape.
Facing forward the medial aspect is convex and the lateral aspect concave. It can be divided into a sternal end a shaft and an acromial end. Over here we have the sternal end.
This would be the shaft. Then if we were to look at the structures on the clavicle here we have the deltiod tubercle. Over here we have the conoid tubercle and we have the trapezoid line.
We have the subclavian groove and we have the costal tuberosity. Those are all the structures for now. Although the neurovascular structures are in close proximity to the medial half of the clavicle they are protected from the bone by a continuous myofascial tissue layer extending from the omohyoid fascia in the neck down to the clavipectoral fascia which encases the pectoralis minor and subclavius muscles.
This layer is evident in comminuted fractures and retained in non-unions. Each clavicle runs transversely and forms a joint with the sternum on its medial end and the scapula on its lateral end. The medial end of each clavicle is a smooth rounded cylinder known as the sternal extremity which forms the sternoclavicular joint with the manubrium of the sternum.
The clavicle also collarbone Latin. Clavicula is a paired long bone extending between the sternum and the scapula. The clavicle can be palpated along its length and can is visible under the skin in a thin person.
The clavicle is slender bone with two curves giving it an S shape. The coracoclavicular ligament is a very strong structure effectively suspending the weight of the upper limb from the clavicle. SHAFT The shaft of the clavicle is split into two parts.
Lateral one-third and medial two-third. The clavicle or collarbone a long bone with a shaft and two ends it can be easily palpated and it is one of the most ordinarily fractured bones in the body. The two clavicles on either side of the anterior base of the neck are horizontal S-curved that articulate laterally articulate with the outer end.
Today we will learn the structure of the Clavicleclaviclestructure of the Claviclethe Claviclethe previous video linkhttpsyoutubeN5xxgwCCwzM. The clavicle is a double curved long bone which connects the arm to the trunk. It articulates medially with the sternum at the sternoclavicular joint and laterall with the acromion process of the scapula.
It can be divided into three parts. The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. It serves as a connection between the axial and appendicular skeleton in conjunction with the scapula and each of these structures forms the pectoral girdle1.
The two clavicles also called your collarbones are long bones found between your sternum and scapulae. They are found just above the first rib and help hol. This unlabeled quiz of the clavicle and scapula will test your knowledge on how to label the structures of these bones.
You will be required to label the suprascapular notch supraspinous fossa glenoid cavity medialsuperiorinferiorlateral borders acromion coracoid process trapezoid line etc. You can review the clavicle and scapula anatomy. The clavicle the structures mentioned work jointly as a circulation and ventilation pump for the arm head and neck.
The word clavicula is a diminutive of clavis key but its meaning may equally well be door handle. Medially the clavicle has a ventrally-directed convexity laterally. Below the clavicle lie the important neurovascular structures.
The subclavian vessels and brachial plexus. These are protected by the clavipectoral fascia within the costoclavicular space. The medial cord of the brachial plexus ulnar nerve is located in the smallest portion of the costoclavicular space and can be compromised by fracture or.
Supporting structure of the sternoclavicular joint that surrounds the entire joint and is reinforced by the anterior and posterior sternoclavicular joint ligaments joint capsule supporting structure of the sternoclavicular joint that spans the jugular notch connecting the superior medial aspects of the clavicles and limits clavicular depression.
