[Active and passive mechanical properties of the wall of the lymphangion]. 1989

G I Lobov, and R S Orlov, and M A Kostikova

The modules of elasticity of circular stripes of lymphangion wall were 3.5.10(4) N.m-2, and those of longitudinal stripes were 1.5.10(5) N.m-2. The module of elasticity of intact lymphangions ranged from 1.2.10(4) to 5.2.10(4) N.m-2. The volume-pressure relationship in intact lympangions were similar to length-force relationship in circular stripes. Spontaneous contractions were only evoked by distention of circular stripes. These findings suggest that smooth muscle of circular layer of lymphangion's wall seems to play a basic role in pumping function of lymphangions.

D009130	Muscle, Smooth	Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.
