  • What is the Anatomical Position?
    A standard reference point in anatomy where the body is standing upright, facing forward, arms at the sides, and palms facing forward.
  • Define Axial region.
    Pertaining to the head, neck, and trunk of the body.
  • Define Appendicular region.
    Pertaining to the arms and legs.
  • Name three anterior body regions.
    Examples include Abdominal, Mammary, and Axillary.
  • Name three posterior body regions.
    Examples include Dorsal, Lumbar, and Scapular.
  • What does Superior mean in body orientation?
    Toward the head or upper part of a structure.
  • What does Inferior mean in body orientation?
    Away from the head or toward the lower part of a structure.
  • Define Anterior and Posterior.
    Anterior means toward the front of the body; Posterior means toward the back.
  • What do Medial and Lateral mean?
    Medial means toward the midline of the body; Lateral means away from the midline.
  • Explain Proximal and Distal.
    Proximal means closer to the point of attachment; Distal means farther from the point of attachment.
  • What is a Sagittal section?
    A vertical plane dividing the body into right and left parts.
  • What is a Midsagittal section?
    A sagittal plane that divides the body into equal right and left halves.
  • What is a Parasagittal section?
    A sagittal plane offset from the midline, dividing the body into unequal right and left parts.
  • Define Frontal (Coronal) section.
    A vertical plane dividing the body into anterior (front) and posterior (back) parts.
  • Define Transverse (Cross) section.
    A horizontal plane dividing the body into superior (upper) and inferior (lower) parts.
  • What are the subdivisions of the Dorsal body cavity?
    The Cranial cavity and the Spinal cavity.
  • What are the subdivisions of the Ventral body cavity?
    The Thoracic cavity, Abdominal cavity, and Pelvic cavity.
  • Name the four Abdominopelvic quadrants.
    Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), Left Lower Quadrant (LLQ).
  • List some Abdominopelvic regions.
    Umbilical, Epigastric, Hypogastric, Iliac, Lumbar, Hypochondriac.
  • What does Superficial and Deep mean in body orientation?
    Superficial means toward or on the surface; Deep means away from the surface, more internal.
