  1. Anatomy A small mass or lump of body tissue that either occurs naturally, as in the case of lymph nodes, or is a result of disease.
  2. Botany
    1. A point on a stem where a leaf is or has been attached.
    2. A swelling or lump on a tree; a knob or knot.
    3. Either of the two points on the celestial sphere at which the path of a revolving body, such as the Moon, a planet, or a comet, intersects the ecliptic. The point at which the body traverses from south of the ecliptic to north is the ascending node. The opposite point, when the body traverses the ecliptic from north to south, is the descending node.
    4. Either of the two points at which the orbit of an artificial satellite intersects the equatorial plane of the planet it is orbiting.
  3. Physics A point or region of a vibrating or oscillating system, such as the standing wave of a vibrating guitar string, at which the amplitude of the vibration or oscillation is zero. Harmonic frequencies in oscillating systems always have nodes. Compare antinode.
  4. Astronomy
    1. Either of the two points on the celestial sphere at which the path of a revolving body, such as the Moon, a planet, or a comet, intersects the ecliptic. The point at which the body traverses from south of the ecliptic to north is the ascending node. The opposite point, when the body traverses the ecliptic from north to south, is the descending node.
    2. Either of the two points at which the orbit of an artificial satellite intersects the equatorial plane of the planet it is orbiting.

1. A knot, a knob; a protuberance; a swelling.

2. Specifically: (a) (Astron.) One of the two points where the orbit of a planet, or comet, intersects the ecliptic, or the orbit of a satellite intersects the plane of the orbit of its primary. (b) (Bot.) The joint of a stem, or the part where a leaf or several leaves are inserted. (c) (Dialing) A hole in the gnomon of a dial, through which passes the ray of light which marks the hour of the day, the parallels of the sun's declination, his place in the ecliptic, etc. (d) (Geom.) The point at which a curve crosses itself, being a double point of the curve. See Crunode, and Acnode. (e) (Mech.) The point at which the lines of a funicular machine meet from different angular directions; -- called also knot. --W. R. Johnson. (f) (poet.) The knot, intrigue, or plot of a piece. (g) (Med.) A hard concretion or incrustation which forms upon bones attacked with rheumatism, gout, or syphilis; sometimes also, a swelling in the neighborhood of a joint. --Dunglison. (h) (Mus) One of the fixed points of a sonorous string, when it vibrates by aliquot parts, and produces the harmonic tones; nodal line or point. (i) (Zo["o]l.) A swelling.

Ascending node (Astron.), the node at which the body is passing northerly, marked with the symbol [astascending], called the Dragon's head. Called also northern node.

Descending node, the node at which the body is moving southwardly, marked thus [astdescending], called Dragon's tail.
