In human anatomy, the clavicle, or collarbone, is a bone that serves as a strut between the scapula and the top of the sternum. This bone is the only long bone in the body that lies horizontally. This bone meets with the scapula which makes up the shoulder. This real clavicle would make a great addition to a doctor’s office or anatomy classroom.

We believe that education is the most valuable contribution osteology can offer, and that each human specimen plays a vital role in advancing scientific knowledge. These specimens are generously provided by retired physicians, medical researchers, dental professionals, and former university medical programs. Additionally, we collaborate with accredited donor programs. A select collection of specimens—often antiques that do not meet the criteria for medical or research-grade use—are made available to osteology enthusiasts around the world, allowing them to continue their educational efforts and share knowledge.

Real Human Clavicle: A Comprehensive Guide to Structure, Function, and Uses

Introduction

One of the main structural elements of the human skeletal system is the actual human clavicle, often known as the collarbone. The clavicle, which runs horizontally across the top of the chest and joins the scapula (shoulder blade) and sternum (breastbone), is essential to the movement and functionality of the upper body. It is crucial to comprehend the anatomy and importance of the actual human clavicle, regardless of whether you are a medical student, a professional anatomist, or an osteological specimen collector.

The anatomy, purpose, clinical significance, and ethical issues surrounding the acquisition and study of actual human clavicle bones are examined in this article.

Anatomy of the Human Clavicle

The long, S-shaped clavicle bone acts as a strut between the sternum and the shoulder. Usually, each person has two clavicles: one on the right side of the body and one on the left.

Key Anatomical Features:

  1. Sternal End:

    • Medial part that connects to the manubrium of the sternum.

    • Forms the sternoclavicular joint.

  2. Acromial End:

    • Lateral part that connects to the acromion of the scapula.

    • Forms the acromioclavicular joint.

  3. Shaft:

    • The body of the clavicle.

    • Slightly curved to provide strength and flexibility.

    • Serves as an attachment point for several muscles including the deltoid, pectoralis major, and trapezius.

Function of the Clavicle

The clavicle is more than just a bone – it is a critical biomechanical support structure that facilitates several essential functions:

  • Acts as a strut to keep the scapula in position, allowing for greater range of motion in the arm.

  • Protects neurovascular structures such as the brachial plexus and subclavian vessels.

  • Absorbs mechanical stress from upper limb movement and transmits it to the axial skeleton.

Clinical Importance

In several medical specialties, including orthopedics, physical therapy, and forensic science, an understanding of the actual human clavicle is crucial.

Common Medical Conditions:

  • Clavicle Fracture:

    • One of the most frequently broken bones in the human body.

    • Typically caused by falls or sports injuries.

  • Osteolysis of the Distal Clavicle:

    • Often seen in weightlifters.

    • Involves the resorption of bone near the acromial end.

  • Congenital Clavicle Malformations:

    • Rare cases like cleidocranial dysostosis result in absent or underdeveloped clavicles.

Real Human Clavicle for Educational and Research Purposes

Real human clavicle specimens provide unparalleled authenticity for study for educational institutions, medical schools, and anatomical collectors. Real bones provide authentic anatomical variety, texture, and density that are crucial for education and research, in contrast to plastic models or 3D printouts.

Benefits of Using Real Human Bones:

  • Authentic Learning Experience:

    • Trainees can appreciate natural anatomical differences.

  • Forensic Training:

    • Helps in identifying age, sex, and pathology from skeletal remains.

  • Anthropological Studies:

    • Provides insight into evolutionary biology, bone development, and cultural practices.

Legal and Ethical Considerations

Local, national, and international rules must be followed when studying or possessing real human bones, including clavicles. The sale and exhibition of human remains are strictly regulated in many nations.

Key Considerations:

  • Provenance:

    • Bones should come from ethical, documented sources, such as medical donations or disused educational collections.

  • Compliance with Laws:

    • In the U.S., human bones are legal to own in most states, but always verify local legislation.

  • Respect and Dignity:

    • Specimens must be treated with scientific respect and not for entertainment or shock value.

How to Identify a Real Human Clavicle

Distinguishing a real clavicle from a synthetic replica requires close observation:

  1. Weight:

    • Real bones are denser and heavier than plastic.

  2. Surface Texture:

    • Genuine bones have a porous, irregular surface with subtle color variations.

  3. Anatomical Detail:

    • Real bones show nuanced features like muscle attachment ridges and nutrient foramina.

  4. Sound:

    • When tapped, real bone has a solid, dull resonance compared to the hollow sound of resin.

Where to Obtain Real Human Clavicle Bones

Real human clavicle bones may be available for purchase from reputable anatomical suppliers and osteological curators; these bones are typically used for research or teaching purposes. Always ask for proof of the specimens’ legality and place of origin.

Examples of Sources:

  • University surplus collections

  • Medical teaching institutions

  • Certified osteological suppliers

Conclusion

A window into the intricate structure of the human body, the real human clavicle is more than just a structural bone. Its study offers vital insights into function, shape, and pathology, whether for anthropological research, forensic investigation, or medical instruction.

A genuine clavicle specimen, if obtained properly and legally, provides unparalleled detail for anyone wishing to investigate human anatomy in an accurate manner. These bones should be handled with the highest care, reverence, and respect, just like any other human remains.
