Antibody Structure Diagram - Visual Guide to Immunoglobulin Shape #11370 (License: Personal Use)

This image displays a stylized, bright green 3D model of an antibody (immunoglobulin), emphasizing its characteristic Y-shaped quaternary structure. The two upper arms represent Fab (antigen-binding fragment) regions, while the stem denotes the Fc (crystallizable fragment) region involved in immune cell activation. The smooth, tactile texture suggests a foam or plastic educational model used for teaching immunology concepts.

Commonly used in educational websites, medical textbooks, and science outreach materials to illustrate basic antibody architecture; matches user intent for learning about immune system components or preparing biology presentations.
