  • What are the two main body regions?
    The axial region includes the head, neck, and trunk, while the appendicular region includes the upper and lower limbs.
  • What is the axial region?
    The axial region consists of the head, neck, and trunk.
  • What does the appendicular region include?
    The appendicular region includes the upper and lower limbs.
  • What are planes of section?
    Planes of section are standard ways of dividing a body or body part to examine its internal structure.
  • What does the sagittal plane divide?
    The sagittal plane divides the body or body part into right and left sections.
  • What is the midsagittal plane?
    The midsagittal plane, or median plane, divides the body into equal right and left halves.
  • What is the parasagittal plane?
    The parasagittal plane divides the body into unequal right and left sections.
  • What does the frontal plane divide?
    The frontal plane, or coronal plane, divides the body into anterior (front) and posterior (back) sections.
  • Why is the frontal plane easy to remember?
    Because it divides the body into a front section and a back section.
  • What is another name for the transverse plane?
    The transverse plane is also called the horizontal plane or cross section.
  • What does the transverse plane divide?
    It divides the body or body part into superior (upper) and inferior (lower) parts.
  • How does the transverse plane divide the appendicular region?
    It divides the appendicular region into proximal (closer to the trunk) and distal (farther from the trunk) parts.
