  • 1. Of or pertaining to the sides; as, the lateral walls of a house; the lateral branches of a tree. [1913 Webster]

  • 3. Directed to the side; as, a lateral view of a thing. [1913 Webster]
  • Lateral cleavage (Crystallog.), cleavage parallel to the lateral planes.
  • Lateral equation (Math.), an equation of the first degree. [Obs.]
  • Lateral line (Anat.), in fishes, a line of sensory organs along either side of the body, often marked by a distinct line of color.
  • Lateral pressure or stress (Mech.), a pressure or stress at right angles to the length, as of a beam or bridge; -- distinguished from longitudinal pressure or stress.
  • Lateral strength (Mech.), strength which resists a tendency to fracture arising from lateral pressure.
  • Lateral system (Bridge Building), the system of horizontal braces (as between two vertical trusses) by which lateral stiffness is secured. [1913 Webster] lateral

Definition of 'Lateral cleavage'

From: GCIDE
  • Cleavage \Cleav"age\, n.
  • 1. The act of cleaving or splitting. [1913 Webster]
  • 2. (Crystallog.) The quality possessed by many crystallized substances of splitting readily in one or more definite directions, in which the cohesive attraction is a minimum, affording more or less smooth surfaces; the direction of the dividing plane; a fragment obtained by cleaving, as of a diamond. See Parting. [1913 Webster]
  • 3. (Geol.) Division into lamin[ae], like slate, with the lamination not necessarily parallel to the plane of deposition; -- usually produced by pressure. [1913 Webster]
  • Basal cleavage, cleavage parallel to the base of a crystal, or to the plane of the lateral axes.
  • Cell cleavage (Biol.), multiplication of cells by fission. See Segmentation.
  • Cubic cleavage, cleavage parallel to the faces of a cube.
  • Diagonal cleavage, cleavage parallel to ta diagonal plane.
  • Egg clavage. (Biol.) See Segmentation.
  • Lateral cleavage, cleavage parallel to the lateral planes.
  • Octahedral cleavage, Dodecahedral cleavage, or Rhombohedral cleavage, cleavage parallel to the faces of an octahedron, dodecahedron, or rhombohedron.
