Radius & ulna

STRUCTURE & FUNCTION

Understand what you see.

Permit elbow movement and pronation–supination of the forearm.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Radius is lateral in anatomical position and broadens distally
  2. Ulna has a large proximal olecranon and trochlear notch
  3. The radial head is disc shaped
02 / KEY STRUCTURES

Point them out.

Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.

03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

01How would you identify radius & ulna?
SUGGESTED ANSWER

Radius is lateral in anatomical position and broadens distally. Ulna has a large proximal olecranon and trochlear notch. The radial head is disc shaped.

02Which forearm bone primarily articulates with the proximal carpal row?
SUGGESTED ANSWER

The radius articulates with the scaphoid and lunate. The ulna is separated from the carpus by an articular disc.
