It serves as a connection between the axial and appendicular skeleton in conjunction with the scapula and each of these structures forms the pectoral girdle. It is attached on its medial end to the sternum of the thoracic cage which is part of the axial skeleton.
The sternal end is also anchored to the first rib by the costoclavicular ligament.
Clavicle forms what structure. Anatomy Shoulder and Upper Limb Clavicle. This image demonstrates thick cortices and a paucity of trabecular bone within the diaphysis as compared to the medial and lateral ends where the cortices are thinner and the trabecular density is greater. When facing forward the medial part of the clavicle is convex while its lateral aspect is concave.
The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. It is classed as a long bone and can be palpated along its length. The scapula alternatively known as the shoulder blade is a thin flat roughly triangular-shaped bone placed on either side of the upper back.
The acromial end of the clavicle articulates with the acromion of the scapula at the acromioclavicular joint. In thin individuals it is visible under the skin. The joint formed by these two bones is known as the acromioclavicular joint and forms this V-shaped structure.
The bones that attach each upper limb to the axial skeleton form the pectoral girdle shoulder girdle. It attaches to the scapula laterally at the acromioclavicular joint and the sternum breastbone medially at the sternoclavicular joint. B scapula and humerus.
It articulates medially with the sternum at the sternoclavicular joint and laterall with the acromion process of the scapula. 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. 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 clavicle is situated directly above the first rib. The articular surfaces are covered with fibrocartilage as opposed to hyaline cartilage present in the majority of synovial joints. It presents with three parts - sternal medial end a shaft and an acromial lateral end.
Medial end lateral end and shaft. The clavicle is an S-shaped bone that is anchored by strong ligamentous attachments on both its medial and lateral ends. In humans either of two slender bones each articulating with the sternum and a scapula and forming the anterior part of a shoulder.
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. Its medial half is convex anteriorly and its sternal end is enlarged and triangular where it articulates with the manubrium of the sternum at the sternoclavicular SC joint.
The shaft of the clavicle has a double curve in a horizontal plane. Viewed from the anterior position the clavicle forms a convex curve at its medial end before forming a smaller concave curve near its lateral end. This consists of two bones the scapula and clavicle Figure 811.
The sternoclavicular joint consists of the sternal end of the clavicle the manubrium of the sternum and part of the 1 st costal cartilage. The clavicle collarbone is an S-shaped bone located on the anterior side of the shoulder. The clavicle together with the scapula form the pectoral girdle which is also known as the shoulder girdle.
Which of the following bones articulate at the glenohumeral joint. The clavicle is a double curved long bone which connects the arm to the trunk. The clavicle collar bone connects the upper limb to the trunk Fig.
In contrast to the scapula the clavicle forms a joint at its sternal end with the manubrium of the sternum. Muscular attachments to the clavicle include the sternocleidomastoid pectoralis major and subclavius muscles proximally and the. A acromion b coracoid process c coracoid tubercle d glenoid cavity e manubrium.
This bone along with the clavicle and the manubrium of the sternum composes the pectoral shoulder girdle connecting the upper limb of the appendicular skeleton to the axial skeleton. The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. A bone of the pectoral arch.
The scapula shoulder blade lies on the posterior aspect of the shoulderIt is supported by the clavicle which also articulates with the humerus arm bone to form the shoulder jointThe scapula is a flat triangular-shaped bone with a prominent ridge running across its posterior surface. Micro-computed tomography can be used to depict the internal trabecular structure of the clavicle Fig. The clavicle articulates with which of the following structures to form the sternoclavicular joint.
The clavicle collarbone extends between the manubrium of the sternum and the acromion of the scapula. The clavicle has three main functions. The clavicle bone also called collarbone is a small curved bone that sits horizontally on each side of the superior thorax.
This ridge extends out laterally where it forms the bony tip of the shoulder and joins. There are sex differences in clavicle shapefemale clavicles are shorter and thinner than male clavicles. A pair of structures that connect the axial skeleton to the upper limbs is known as the pectoral girdle.
The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. The clavicle is an attachment point for several muscles. It can be divided into three parts.
Its medial or sternal end articulates with the manubrium of the. Structurally the clavicle can be divided into three parts. The clavicle is a slender bone with two curves that gives it an S shape.
It forms articulations or joints with the upper limbs each consisting of a.
