  • What is the dorsal body cavity?
    The dorsal body cavity is located along the back of the body and includes the cranial cavity and the vertebral (spinal) cavity.
  • Name the two main subdivisions of the ventral body cavity.
    The ventral body cavity is divided into the thoracic cavity and the abdominopelvic cavity.
  • What organs are contained in the thoracic cavity?
    The thoracic cavity contains the heart, lungs, esophagus, and trachea.
  • Define the abdominopelvic cavity.
    The abdominopelvic cavity is the lower part of the ventral cavity, containing the abdominal and pelvic cavities, which house digestive organs, urinary bladder, and reproductive organs.
  • What is the function of the serous membranes in body cavities?
    Serous membranes line body cavities and cover organs, reducing friction between moving organs.
  • Name the nine regions of the abdominopelvic area.
    The nine regions are: right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, and left iliac.
  • What is the epigastric region?
    The epigastric region is the upper central region of the abdomen, located above the stomach.
  • Where is the hypogastric region located?
    The hypogastric region is the lower central region of the abdomen, below the umbilical region.
  • What are the major body planes used in anatomy?
    The major body planes are sagittal (divides left and right), frontal/coronal (divides front and back), and transverse/horizontal (divides top and bottom).
  • Define the term 'anterior' in anatomical position.
    Anterior refers to the front or forward-facing part of the body.
  • What does 'posterior' mean in anatomy?
    Posterior means toward the back or rear of the body.
  • What is the difference between the axial and appendicular regions?
    The axial region includes the head, neck, and trunk; the appendicular region includes the limbs and their attachments.
  • Name the body cavity that houses the brain.
    The cranial cavity houses the brain.
  • What cavity contains the spinal cord?
    The vertebral (spinal) cavity contains the spinal cord.
  • Where is the pleural cavity located?
    The pleural cavity is within the thoracic cavity and surrounds each lung.
  • What is the pericardial cavity?
    The pericardial cavity is the space within the thoracic cavity that surrounds the heart.
  • Define the term 'medial' in anatomical terms.
    Medial means toward the midline of the body.
  • What does 'lateral' mean in anatomy?
    Lateral means away from the midline of the body.
  • What is the function of the abdominal cavity?
    The abdominal cavity contains digestive organs such as the stomach, liver, intestines, and kidneys.
  • Where is the pelvic cavity located and what does it contain?
    The pelvic cavity is below the abdominal cavity and contains the urinary bladder, reproductive organs, and rectum.
