  2. Inclinometer - Wikipedia

    en.wikipedia.org/wiki/Inclinometer

    Typical advantages of using two-axis MEMS inclinometers over conventional single-axis "bubble" or mechanical leveling instruments may include: Simultaneous measurement of two-dimensional (X-Y plane) tilt angles (i.e. pitch & roll), can eliminate tedious swapping back-and-forth experienced when using a single-axis level, for example to adjust ...

  3. Tiltmeter - Wikipedia

    en.wikipedia.org/wiki/Tiltmeter

    A newer technology using microelectromechanical systems (MEMS) sensors enables tilt angle measuring tasks to be performed conveniently in both single and dual axis mode. Ultra-high precision 2-axis MEMS driven digital inclinometer/ tiltmeter instruments are available for speedy angle measurement applications and surface profiling requiring very ...

  4. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    To do this, distinct ends of an organism are chosen, and the axis is named according to those directions. An organism that is symmetrical on both sides has three main axes that intersect at right angles. [3] An organism that is round or not symmetrical may have different axes. [3] Example axes are: The anteroposterior axis [8] The cephalocaudal ...

  5. Axis (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Axis_(anatomy)

    In anatomy, the axis (from Latin axis, "axle") is the second cervical vertebra (C2) of the spine, immediately inferior to the atlas, upon which the head rests. The spinal cord passes through the axis. The defining feature of the axis is its strong bony protrusion known as the dens, which rises from the superior aspect of the bone.

  6. Standard anatomical position - Wikipedia

    en.wikipedia.org/wiki/Standard_anatomical_position

    The standard anatomical position, or standard anatomical model, is the scientifically agreed upon reference position for anatomical location terms.Standard anatomical positions are used to standardise the position of appendages of animals with respect to the main body of the organism.

  7. Anatomical plane - Wikipedia

    en.wikipedia.org/wiki/Anatomical_plane

    In human anatomy, the anatomical planes are defined in reference to a body in the upright or standing orientation. A transverse plane (also known as axial or horizontal plane) is parallel to the ground; it separates the superior from the inferior, or the head from the feet.

  8. Random positioning machine - Wikipedia

    en.wikipedia.org/wiki/Random_positioning_machine

    The RPM is a more sophisticated development of the single-axis clinostat. RPMs usually consist of two independently rotating frames. RPMs usually consist of two independently rotating frames. One frame is positioned inside the other giving a very complex net change of orientation to a biological sample mounted in the middle.

  9. Sinistral and dextral - Wikipedia

    en.wikipedia.org/wiki/Sinistral_and_dextral

    Sinistral and dextral, in some scientific fields, are the two types of chirality ("handedness") or relative direction.The terms are derived from the Latin words for "left" (sinister) and "right" (dexter).
