What's the difference between erector and inverted?

Erector


Definition:

  • (n.) A muscle which raises any part.
  • (n.) An attachment to a microscope, telescope, or other optical instrument, for making the image erect instead of inverted.

Inverted


Definition:

  • (imp. & p. p.) of Invert
  • (a.) Changed to a contrary or counterchanged order; reversed; characterized by inversion.
  • (a.) Situated apparently in reverse order, as strata when folded back upon themselves by upheaval.

Example Sentences:

  • (2) In crosses between inverted repeats, a single intrachromatid reciprocal exchange leads to inversion of the sequence between the crossover sites and recovery of both genes involved in the event.
  • (3) The result of this study demonstrates that both the "hat" and "inverted" type grafts are highly successful and satisfactory procedures.
  • (4) Plasmids containing the inverted repeat alone bound ER, though less efficiently than did plasmids containing the entire sequence.
  • (5) IS1106 has a length of 1137 bp and is flanked by 36bp inverted repeats.
  • (6) The responses were compared when two electrode pairs were stimulated simultaneously with current pulses in phase and when the same electrodes were stimulated with current pulses inverted relative to each other.
