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.

Flashcards

Anatomical Position

A standard body orientation used to describe anatomical terms: standing upright with arms hanging by sides, palms forward, thumbs away from the body, feet flat and pointing forward, head and eyes straight ahead.

Body Planes

Imaginary lines drawn through an upright body in anatomical position that divide the body into sections or portions.

Body Sections

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

Sagittal Plane

Vertical plane running top to bottom and front to back, dividing the body into right and left portions. Mid-sagittal is through the midline, Para-sagittal is off-center.

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
