Questions and Answers

What is a sagittal section?

  • Cut made along a horizontal plane, dividing the body into superior and inferior parts
  • Cut made down the median plane with equal right and left parts

    • What is a midsagittal (median) section?

    Cut made down the median plane of the body where right and left parts are equal.

    What does a frontal (coronal) section do?

  • Divides the body into right and left parts

    Study Notes

    Body Planes and Sections

    • Sagittal Section: A longitudinal cut dividing the body into right and left parts.
    • Midsagittal (Median) Section: A cut along the median plane resulting in equal right and left halves.
    • Frontal (Coronal) Section: A lengthwise cut that divides the body into anterior (front) and posterior (back) parts.
    • Transverse (Cross) Section: A horizontal cut dividing the body or organ into superior (upper) and inferior (lower) parts.

    Body Cavities

    • Dorsal Body Cavity: Contains the cranial cavity and the spinal cavity, protecting the brain and spinal cord respectively.
    • Cranial Cavity: The space within the skull that houses the brain.
    • Spinal Cavity: Extends from the cranial cavity down the vertebral column, enclosing and protecting the spinal cord with vertebrae.

    Ventral Body Cavity

    • Ventral Body Cavity: Larger than the dorsal cavity, containing structures in the thorax and abdomen.
    • Thoracic Cavity: The superior section of the ventral cavity, separated by the diaphragm; includes the mediastinum, which divides the lungs and houses the heart and trachea.
    • Abdominopelvic Cavity: Located inferior to the diaphragm, further divided into abdominal and pelvic cavities.

    Abdominal and Pelvic Cavities

    • Abdominal Cavity: Houses vital organs such as the stomach, liver, and intestines.
    • Pelvic Cavity: Located below the abdominal cavity, containing reproductive organs, bladder, and rectum.
