Body Cavities and Membranes Quiz – Anatomy and Physiology
1. The body has two major cavities and several minor cavities.
a. True
b. False
The answer is a, true. The body has two main cavities: the dorsal cavity and the ventral cavity. These can be
subdivided into other cavities, such as the thoracic, cranial, vertebral, and abdominopelvic cavities. There are
also minor cavities in the body, such as the nasal or oral cavity.
2. Which structure below is not found in the thoracic cavity?
a. Pleural cavity
b. Pericardial cavity
c. Mediastinum
d. Peritoneal cavity
The answer is d, peritoneal cavity. The peritoneal cavity is found in the abdominopelvic cavity.
3. The dorsal cavity includes the cranial and thoracic cavity.
a. True
b. False
The answer is b, false. The dorsal cavity contains the cranial cavity and the vertebral cavity. The thoracic cavity
located in the ventral cavity.
4. Which landmark separates the thoracic cavity from the abdominopelvic cavity?
a. The peritoneum
b. The diaphragm
c. The liver
d. The bladder
The answer is b, the diaphragm. The diaphragm is a muscle that helps us breathe, and it physically separates
the thoracic cavity from the abdominopelvic cavity. The dorsal cavity is continuous, which means it does not hav
a physical separation. The abdominal cavity is also continuous with the pelvic cavity.
5. The three membranes found in the dorsal cavity that cover the spinal cord and brain are collectively called
what?
a. Peritoneal membranes
b. Meninges
c. Serous membranes
d. None of the above
