Questions and Answers

What is the primary characteristic of the mid-sagittal plane?

  • It divides the body into equal right and left portions. (correct)
  • It divides the body into top and bottom sections.
  • It runs parallel to the coronal plane.
  • It runs perpendicular to the transverse plane.

    • Which of the following correctly describes the coronal plane?

  • It divides the body into two unequal sections.
  • It separates the body into superior and inferior parts.
  • It runs from front to back.
  • It creates sections of the body along the vertical axis. (correct)

    • What distinguishes an oblique plane from other planes of the body?

  • It is oriented at an angle rather than strictly horizontal or vertical. (correct)
  • It divides the body into equal left and right sections.
  • It can be either vertical or horizontal.
  • It is always equal in dimension.

    Study Notes

    Anatomical Position

    • Refers to a standard body orientation used to describe anatomical terms and structures
    • Standing upright
    • Upper limbs hanging down at the sides and slightly away from the trunk, palms facing forward and thumbs pointing away from the body
    • Lower limbs together, feet flat on the ground and facing forward
    • Head and eyes directed straight ahead

    Body Planes

    • Imaginary lines drawn through an upright body in anatomical position
    • Divide the body into sections or portions

    Body Sections

    • Portions of the body created by a cut made along a body plane

    Sagittal Plane (S)

    • Vertical plane that runs from top to bottom and front to back
    • Divides the body into right and left sections
    • Mid-sagittal (median) plane: runs through the midline of the body and divides it into equal right and left portions
    • Para-sagittal Plane: off-center sagittal plane that divides the body into unequal right and left portions

    Coronal Plane (C)

    • Also known as the frontal plane
    • Vertical plane that runs from top to bottom and right to left
    • Divides the body into a front section and a back section

    Transverse Plane (T)

    • Also known as the axial plane or horizontal plane
    • Horizontal plane that runs from right to left and front to back
    • Divides the body into top and bottom sections

    Longitudinal Plane

    • Any plane perpendicular to the transverse plane
    • Sagittal and coronal planes are examples of longitudinal planes

    Oblique Plane

    • Any plane that is not horizontal or vertical
    • Not sagittal, coronal, or transverse
