The Mechanical System: Muscle and Connective Tissue

A number of factors affect neuromuscular function in the gastrointestinal
tract and so act upon the transport of material. The intrinsic properties of the muscle
account for the mechanics. These properties of the muscle itself establish the
relationships between length, tension and velocity. This chapter deals primarily with the
tissue properties, both active and passive, of the gastrointestinal wall. It seems obvious
that the passive properties are related to non-contractile elements where the active
properties are due to the contraction of the smooth muscle cells. Hill’s three-element
model explains the active and passive elements in the wall and their interaction.
