contractility

Definitions

  • WordNet 3.6
    • n contractility the capability or quality of shrinking or contracting, especially by muscle fibers and even some other forms of living matter
    • ***
Webster's Revised Unabridged Dictionary
    • Contractility (Physiol) The power possessed by the fibers of living muscle of contracting or shortening.
    • Contractility The quality or property by which bodies shrink or contract.
    • ***
Century Dictionary and Cyclopedia
    • n contractility The inherent property or force by which bodies shrink or contract; more specifically, in physiology, the property which belongs to muscles of contracting under appropriate stimuli. The stimulus normally comes through the nerves, and may be accompanied by volition or not; but it may also be applied artificially, either indirectly through the nerves or directly to the muscle itself, as by electricity, mechanical violence, or chemical action.

In science:

However, if the microtubule network is depolymerized using nocodazole, the cell attains a state where the actin system forms a contractile ring which generates a constriction of the cell.
Mechanical oscillations at the cellular scale
Slow oscillations of contractile rings start from several minutes per period; the highest frequencies of active oscillations in hair cells could exceed 100kHz, e.g. during high frequency sound detection in bats and whales. I thank S.
Mechanical oscillations at the cellular scale
In addition, there are compliance devices such as springlike proteins called fibronectin and vorticellids , as well as synthetic contractile plant polymers which can act as compliant joints in biomolecular robotic systems.

Similarly if X is contractible and D is as in (6) the cochain complex of abelian groups ˜F ∗ (△, D(−, X )) is also contractile and contraction is given by the homomorphisms ˆhi : ˜F i (△, D(−, X )) → ˜F i−1 (△, D(−, X )) defined by (ˆhi (c))(m) = hm+i ∗ (c(m)).
