1. Light Chain Hypervariable Region Constant Region Heavy Chain Hinge Region
$\qquad$ Part of the body that binds antigen
Constant regio Contains more than 1 constant region
$\qquad$ The most conserved region of the molecule, which interacts with other immunesystem components (effector function)
$\qquad$ Pairs with the amino-terminal part of the heavy chain to form one of the two arms of the antibody
$\qquad$ Provides flexibility to permit binding to different antigenic arrangements
