An example of the dorsal cavity is what?

1. Abdominal cavity

2. Thoracic cavity

3. Spinal cavity

4. Pelvic cavity

The correct answer is: Spinal cavity

The spinal cavity is indeed a prime example of the dorsal cavity, which is part of the body's major cavities. The dorsal cavity includes areas located at the back of the body, encompassing both the cranial cavity, which houses the brain, and the spinal cavity, which contains the spinal cord. In contrast, the abdominal cavity, thoracic cavity, and pelvic cavity are categorized as ventral cavities. The thoracic cavity, for instance, is situated in the chest area and contains organs like the heart and lungs. The abdominal cavity holds the digestive organs, while the pelvic cavity contains structures associated with the reproductive and excretory systems. Understanding these distinctions is crucial in anatomy, as it helps healthcare professionals identify and locate various organs and systems within the human body during patient assessments, diagnoses, and treatments.
