Which body cavity provides the least protection
Which body cavity provides the most protection?
Explanation: The Cranial Cavity is the most protective as the skull completely encapsulates the brain. Next would be the Vertebral Cavity which surrounds the spinal cord.
What cavity is not protected by bones?
The correct answer is (C) abdominal. The ventral cavity contains the abdominopelvic and thoracic cavities.
Which body cavity is most vulnerable?
The liver and spleen organs are most vulnerable; therefore, it may be beneficial to apply concerted efforts to focus on injury biomechanics research and prioritization activities in these areas of the abdomen.
What does the thoracic body cavity protect?
The thoracic cavity fills the chest and is subdivided into two pleural cavities and the pericardial cavity. The pleural cavities hold the lungs, and the pericardial cavity holds the heart.
Which body cavity is superior to the thoracic cavity?
Ventral body cavity
The superior mediastinum is a wedge-shaped cavity located between the superior regions of the two thoracic cavities.
What body cavities are superior to the diaphragm?
Thoracic cavity–the space occupied by the ventral internal organs superior to the diaphragm.
What is the protective lining of the abdominal cavity?
The peritoneum is thin membrane that lines the abdominal and pelvic cavities, and covers most abdominal viscera. It is composed of layer of mesothelium supported by a thin layer of connective tissue.
Does the thoracic cavity protects the heart and lungs?
The thoracic cavity is actually composed of three spaces each lined with mesothelium, a special film-like tissue that separates vital organs. The pleural cavities surround the lungs, while the pericardial cavity surrounds and protects the heart.
Is the cranial cavity superior or inferior?

What organs does the omentum cover?
The quirkiest organ in the human body may be a large sheet of fat that stretches over the intestines, liver, and stomach like an elastic apron. Sometimes called the ‘policeman of the abdomen,’ the omentum is known to secrete hormones related to obesity, and we’re still learning new information about its functions.
What is covering the organs of the peritoneal cavity?
The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom. It covers most of the intra-abdominal, or coelomic, organs. … The inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the intraperitoneal cavity.
Which cavity is not found in the ventral cavity?
The answer is a, Vertebral. The vertebral and cranial cavities are found in the dorsal cavity, not the ventral cavity.
Which cavity contains the three tiny bones involved in hearing?
Middle ear (tympanic cavity), consisting of: Ossicles. Three small bones that are connected and transmit the sound waves to the inner ear.
What muscle subdivides the ventral body cavity?
The diaphragm is a thin skeletal muscle that subdivides the ventral body cavity, i.e., separates the abdomen from the chest.
Which body cavity contains the peritoneum?
the abdominal cavity
The peritoneum is the serous membrane that lines the abdominal cavity. It is composed of mesothelial cells that are supported by a thin layer of fibrous tissue and is embryologically derived from the mesoderm.
Which structure is not found in the thoracic cavity?
The thoracic cavity contains the lungs and the mediastinum, which contains the heart and its attached blood vessels, the trachea, the esophagus, and all other organs in this region except for the lungs.
What cavity contains the heart?
Heart. The pericardial cavity lies just anterior to the liver. It is enclosed by the pericardial sac and contains the heart (Figure 5.32).
Is the bladder intraperitoneal or retroperitoneal?
The structures within the intraperitoneal space are called “intraperitoneal” (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called “retroperitoneal” (e.g., the kidneys), and those structures below the intraperitoneal space are called ” …
