title: Mechanical properties of lymph node capsule.
abstract: We studied the relationship between the length and tension in isolated strips of the capsules of bovine mesenteric lymph nodes. The deformation-strain and radius-pressure relationships were established in the lymph node. The capsule possesses high distensibility, modulus of elasticity at optimal tension was 0.09×10(5) N/m2. Smooth muscle activation produces a 6-fold increase of modulus of elasticity. Maximum active stress in the capsule was recorded at a length of 1.1 L0 and maximal active pressure (4.5 cm H2O) at 0.9 L0.
