| 영문 | nerve cell | 한글 | 신경세포 |
|---|---|---|---|
| 설명 | 신경세포는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 신경세포에서는 전해져오는 자극을 전기적인 신호로 바뀌어 보내거나 받게 된다. 이런 전기적인 현상은 각 신경세포내에 존재하는 각 이온채널(ion channel: ion이란 나트륨, 칼륨 등을 지칭하는 말들로써, 이들이 세포막에 의해 나뉘어질 때 생기는 전압차가 전기적 자극을 일으키고 유지하는데 결정적인 역할을 한다)들의 작용에 의해 이루어지게 된다. |

|---|---|---|---|
| 설명 | 표정근을 지배하는 큰 운동신경과 작은 중간신경으로 구성된다. 좁은 의미의 얼굴신경과 중간신경으로 이루어지는 혼합신경이다. 속귀신경과 함께 속귓길로 들어가고 그 바닥에서 속귀신경과 갈라져 얼굴신경관으로 들어가, 거의 직각으로 구부러지는 부분을 얼굴신경무릎이라 하며, 여기에 무릎신경마디가 있다. |

|---|---|---|---|
| 설명 | 척수의 앞뿔에서 출발하는 운동신경과 뒷뿔으로 들어오는 감각신경이 합쳐서 형성되는 신경으로서 총 31쌍이 존재함. 목뼈신경이 8쌍, 자등뼈신경이 12쌍, 허리뼈의 신경이 5쌍, 엉치뼈의 6쌍을 이룸. |

| 영문 | auditory nerve | 한글 | 청신경 |
|---|---|---|---|
| 설명 | 귀에서 감지된 청각의 신호를 대뇌로 보내는 역할을 하는 신경. 달팽이신경라고 불리기도 한다. 그것은 소리를 전기적 신호로 바꾸어 신경으로 전달해 주는 달팽이의 집같이 생긴 기관을 달팽이라고 부르기 때문이다.  |

| drift cyclotron loss cone instabilities | (DCLC) This is an electrostatic microinstability (frequencies at harmonics of the ion cyclotron frequency) which is of major concern in small mirror devices. Mode is driven by radial gradients in the electron density, and causes loss of ions due to non-conservation of magnetic moment (see adiabatic invariant) as they interact with the mode, and are dispersed in velocity space into the loss cone. Stabilisation is accomplished by increasing the plasma size and by partially filling the loss cone with a continuous extermal warm plasma stream. (09 Oct 1997) |

| loss cone | In a magnetic mirror machine, particles with a large velocity parallel to the magneitc field and a small velocity perpendicular to the field will be able to escape past the magnetic mirror (see magnetic mirror). In that case the velocity distribution function (see distribution function) will be almost zero in the region of velocity space that allows particles to escape. The shape of that region (in a velocity space diagram with parallel velocity and perpendicular velocity as the axes) is a cone. When a particle undergoes a collision, its velocity gets somewhat randomised. Particles that are scattered into that cone are lost very quickly (in one mirror bounce time). Thus it is called a loss cone. Because of the loss cone, the theoretical maximum particle confinement time of a magnetic mirror machine can be only a few times the particle collision time, this is generally seen as a showstopper for mirror-based fusion research.
