(20) The cellular mechanisms responsible for the differences in the firing behavior of flexor and extensor motoneurons are currently being investigated using techniques that are only possible using the in vitro preparation.
Muscle
Definition:
(n.) An organ which, by its contraction, produces motion.
(n.) The contractile tissue of which muscles are largely made up.
(n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
(n.) See Mussel.
Example Sentences:
(1) The extents of phospholipid hydrolysis were relatively low in brain homogenates, synaptic plasma membranes and heart ventricular muscle.

(9) In addition to their involvement in thrombosis, activated platelets release growth factors, most notably a platelet-derived growth factor (PDGF) which may be the principal mediator of smooth muscle cell migration from the media into the intima and of smooth muscle cell proliferation in the intima as well as of vasoconstriction.
(10) Further, the maximal increase in force of contraction was measured using papillary muscle strips from some of these patients.
(11) Peripheral eosinocytes increased by 10%, and tests for HBsAg, antiHBs, antimitochondrial antibody and anti-smooth muscle antibody were all negative.
