Question

The only direct connection between the pectoral girdle and the axial skeleton is where the A) clavicle articulates with the humerus. B) clavicle articulates with the manubrium of the sternum. C) coxal bones articulate with the femur. D) vertebral column articulates with the sacrum. E) clavicle articulates with the xiphoid process.

Answer 1

Answer:

The correct answer is B. clavicle articulates with the manubrium of the sternum.

Explanation:

The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. The sternal end is also anchored to the first rib by the costoclavicular ligament. The medial end, also known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.

Answer 2

The only direct connection between the pectoral girdle and the axial skeleton is where the - B) clavicle articulates with the manubrium of the sternum.

A pectoral girdle or shoulder girdle connects your upper limbs to the bones along the axis of your body. There are two pectoral girdles in your body.

• The pectoral girdle consists of the two bones that make up your shoulder: clavicle, or collarbone and scapula, or shoulder blade.

• The bones that form the axial skeleton consists of the bones of the head, trunk and vertebrate. For example sternum, ribcage, skull bones

• The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint.

Thus, the only direct connection between the pectoral girdle and the axial skeleton is where the - B) clavicle articulates with the manubrium of the sternum.
