Sternal End

Definition

The sternal end is the medial or inner end of the clavicle (collarbone) where it connects to the sternum, the flat bone in the center of the chest. This bony connection is an important component of the pectoral girdle, the structure that attaches the upper limb to the axial skeleton.

5 Must Know Facts For Your Next Test

1. The sternal end of the clavicle is the medial or inner end of the bone that connects to the sternum.
2. This bony connection between the clavicle and sternum is a crucial component of the pectoral girdle, providing stability and support for the shoulder joint.
3. The sternal end of the clavicle can be palpated and is an important landmark for physical examination and medical procedures.
4. Injuries to the sternal end of the clavicle, such as fractures or dislocations, can be particularly painful and debilitating, affecting the function of the shoulder and upper limb.
5. The sternal end of the clavicle develops from a separate ossification center and can sometimes fail to fuse properly, leading to congenital abnormalities.

Review Questions

• Describe the anatomical location and function of the sternal end of the clavicle.
  • The sternal end of the clavicle is the medial or inner end of the collarbone where it connects to the sternum, the flat bone in the center of the chest. This bony connection is a crucial component of the pectoral girdle, the skeletal structure that attaches the upper limb to the axial skeleton. The sternal end of the clavicle provides stability and support for the shoulder joint, allowing for the mobility and range of motion of the upper limb.
• Explain the importance of the sternal end of the clavicle in the context of the pectoral girdle.
  • The sternal end of the clavicle is an essential part of the pectoral girdle, the skeletal structure that connects the upper limb to the axial skeleton. The clavicle, with its sternal end, is one of the two bones that make up the pectoral girdle, along with the scapula. This bony connection between the clavicle and sternum provides the necessary stability and support for the shoulder joint, allowing for the wide range of motion and mobility of the upper limb. Injuries or abnormalities affecting the sternal end of the clavicle can significantly impact the function and movement of the shoulder and upper extremity.
• Analyze the clinical significance of the sternal end of the clavicle and its potential implications for medical care.
  • The sternal end of the clavicle is an important anatomical landmark that has significant clinical relevance. As the medial attachment point of the clavicle to the sternum, the sternal end can be easily palpated and is a crucial reference point for physical examinations, medical procedures, and the diagnosis of injuries. Fractures or dislocations of the sternal end of the clavicle can be particularly debilitating, as they can compromise the stability and function of the shoulder joint. Additionally, congenital abnormalities in the development and fusion of the sternal end may require specialized medical attention and treatment. Understanding the anatomy and significance of the sternal end of the clavicle is essential for healthcare professionals to provide effective and informed patient care.

Pectoral Girdle:

The pectoral girdle is the skeletal structure that connects the upper limb to the axial skeleton. It consists of the clavicle and scapula, and is responsible for the mobility and stability of the shoulder joint.

Clavicle:

The clavicle, or collarbone, is a long, slender bone that connects the scapula to the sternum. It is the only bony connection between the upper limb and the axial skeleton.

Sternum:

The sternum is a flat bone located in the center of the chest. It serves as the attachment point for the ribs and the clavicles, and is an important component of the thoracic cavity.
