STRUCTURE & FUNCTION

Understand what you see.

Supports T-cell development and selection.

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. Lobules with dark cortex and paler medulla
  2. Hassall corpuscles in medulla
  3. No ordinary lymphoid follicles
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.

  • Hassall corpuscles
03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

01How do you identify thymus?
SUGGESTED ANSWER

Lobules with dark cortex and paler medulla. Hassall corpuscles in medulla. No ordinary lymphoid follicles.

02What forms Hassall corpuscles?
SUGGESTED ANSWER

Concentrically arranged epithelial reticular cells in the medulla.

03Does it normally have germinal-centre follicles?
SUGGESTED ANSWER

No. Such follicles are characteristic of other lymphoid tissues, not the normal thymic architecture.

04Which structures should you point out on this reference?
SUGGESTED ANSWER

Cortex; Medulla; Hassall corpuscles. Supports T-cell development and selection.
