What's the difference between crosspiece and perpendicular?

Crosspiece


Definition:

  • (n.) A piece of any structure which is fitted or framed crosswise.
  • (n.) A bar or timber connecting two knightheads or two bitts.

Example Sentences:

  • (3) The cell wall was found to be 20--25 nm thick and to consist of a rigid layer bound to the cytoplasmic membrane with crosspieces.
  • (4) A second suture can be attached to the proximal limb of the crosspiece to extract it end-on at a latter date without enlarging the tract.
  • (5) The ocular asymmetry measuring device comprises a headband, a ruler, and a T-shaped crosspiece.
  • (6) Because the crosspiece and the stem are held together with sutures, they can be aligned over a catheter and guide wire for atraumatic insertion into the bile duct.

Perpendicular


Definition:

  • (a.) Exactly upright or vertical; pointing to the zenith; at right angles to the plane of the horizon; extending in a right line from any point toward the center of the earth.
  • (a.) At right angles to a given line or surface; as, the line ad is perpendicular to the line bc.
  • (n.) A line at right angles to the plane of the horizon; a vertical line or direction.
  • (n.) A line or plane falling at right angles on another line or surface, or making equal angles with it on each side.

Example Sentences:

  • (1) Our data support the hypothesis that evoked and epileptiform magnetic fields result from intradendritic currents oriented perpendicular to the cortical surface.
  • (2) Right ventricular volumes were determined in 12 patients with different levels of right and left ventricular function by magnetic resonance imaging (MRI) using an ECG gated multisection technique in planes perpendicular to the diastolic position of the interventricular septum.
  • (3) We attribute the greater strength of the step-cut repair to the additional number of epitendinous loops, which lie perpendicular to the long axis of the tendon.
  • (4) The helix axes, penetrating the hydrophobic region of the bilayers, were oriented neither parallel nor perpendicular to the membrane normal.
  • (5) We show that over a limited range of high spatial frequencies this noise takes on a striated appearance, with the striations running perpendicular to the true fringe orientation.
  • (6) The AFB1 moiety is face-stacked in the major groove with its long axis approximately perpendicular to the helix axis.
  • (7) The two molecules in the asymmetric unit form a dimer with its 2-fold axis perpendicular to and intersecting with a crystallographic 4(1) axis.
  • (8) Interestingly, the helical motif prefers to assemble parallel to the wall, whereas the beta-barrel, predominantly assembles with its principal axis perpendicular to the wall.
  • (9) The numerals were either upright, or inverted, or rotated perpendicular to the arm axis.
  • (10) Parameters measured from simulator films included: (a) the perpendicular distance from the posterior tangential field edge to the posterior part of the anterior chest wall at the center of the field (CLD); (b) the maximum perpendicular distance from the posterior tangential field edge to the posterior part of the anterior chest wall (MLD); and (c) the length of lung (L) as measured at the posterior tangential field edge on the simulator film.
  • (11) Our results suggest that the first stage is much more selective for orientation than are lateral geniculate nucleus cells, but that the first-stage orientation bandwidth is rather wide with some interaction occurring between perpendicular orientations.
  • (12) In slices cut parallel to the pyramidal neurons (perpendicular to the brain surface) one can study chemosensitivity of the various parts of the dendritic tree and the soma.
  • (13) The bands encircle the muscle fiber perpendicular to the long axis of the fiber and they matched the sites of attachment of the sarcomeres to the plasma membrane.
  • (14) Thin section analysis of capped cells revealed an abundance of microtubules immediately beneath the cap which were arranged approximately perpendicular to the plane of the membrane.
  • (15) This procedure allowed both light and electron microscopic examination of serial-step sections of individual cells cut in a plane perpendicular to the monolayer.
  • (16) If a segment of a line differs in luminance or color from the rest of the line, three illusory phenomena may be perceived: a reduction in contrast of the line segment relative to the background, subjective contours running perpendicularly to the ends of the line segment, and spread of color or brightness surrounding the line segment.
  • (17) Typically they lie perpendicular to the cell membrane of the pinealocyte polar process and in close proximity to a polar process of a neighboring cell.
