| second-stability region | <radiobiology> A high pressure region where the plasma becomes stable to the pressure-gradient-driven ballooning instability. The plasma is stable in the limit of small pressure gradients, becomes unstable at some intermediate pressure, and then becomes stable again at still higher pressures. Tokamaks operating in the second-stability region would be more attractive because the higher pressures (beta) would provide more fusion reactivity per unit volume of plasma, allowing smaller reactors to be built.

| neoplasms, second primary | Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause. (12 Dec 1998) |

| medial plantar nerve | <anatomy, nerve> One of the two terminal branches of the tibial nerve; it courses along the medial aspect of the sole to supply the abductor hallucis and flexor digitorum brevis and, by way of common and proper digital branches, to innervate the skin of the medial part of the foot and medial three and one-half toes. Synonym: nervus plantaris medialis. (05 Mar 2000) |
