The ulna is medial compared to the radius. COMPARE.EDU.VN provides detailed anatomical comparisons to help you understand the relationship between these two bones of the forearm. Explore the functions and key features with our comprehensive guide to improve your anatomical understanding and assist in medical learning.
1. Understanding the Anatomical Position
The ulna is medial compared to the radius in the anatomical position. When the body is standing upright, palms facing forward, the ulna is located on the inner side of the forearm, closer to the midline of the body. Conversely, the radius is on the lateral or outer side of the forearm, further away from the midline. This positioning is crucial for understanding how the forearm functions and how movements like pronation and supination are possible.
1.1. What is the Anatomical Position?
The anatomical position is a standard reference point in anatomy. In this position, the body is erect, with feet slightly apart, arms at the sides, and palms facing forward. This standardized pose ensures consistent descriptions of the relative locations of body parts. The ulna and radius’s medial-lateral relationship is always described in reference to this position, regardless of the actual position of the body.
1.2. Why is Anatomical Position Important?
Understanding anatomical position is essential for clear communication in medicine and anatomy. Without a standard reference, descriptions of the location of structures would be ambiguous and confusing. Whether you are a student, healthcare professional, or just interested in anatomy, knowing this foundational concept is key to accurate anatomical understanding.
1.3. Bones of the Forearm
/images/library/1839/images/basi_il-luut_radii-et-ulnae_anterior-view.png)

2.1. Proximal End of the Ulna
The proximal end of the ulna is characterized by the olecranon, the trochlear notch, and the coronoid process. The olecranon forms the bony prominence at the back of the elbow, providing an attachment point for the triceps brachii muscle. The trochlear notch articulates with the trochlea of the humerus, forming the humeroulnar joint, which is crucial for elbow flexion and extension. The coronoid process projects anteriorly, fitting into the coronoid fossa of the humerus during flexion.
2.2. Ulnar Shaft
The ulnar shaft (or body) is triangular in cross-section and features three borders: the anterior, posterior, and interosseous borders. The interosseous border is particularly important, as it provides an attachment point for the interosseous membrane, which connects the ulna to the radius. The shaft also features three surfaces: anterior, posterior, and medial, each serving as attachment sites for various forearm muscles.
2.3. Distal End of the Ulna
The distal end of the ulna is smaller than its proximal end and consists of the ulnar head and styloid process. The ulnar head articulates with the ulnar notch of the radius, forming the distal radioulnar joint, which allows for pronation and supination. The ulnar styloid process is a small, bony projection that provides attachment for the ulnar collateral ligament of the wrist.
2.4. Key Landmarks
