Textbook Question

Which ventral cavity subdivision has no bony protection?
a. Thoracic cavity
b. Abdominal cavity
c. Pelvic cavity

Verified step by step guidance

Step 1: Begin by understanding the ventral cavity, which is divided into three main subdivisions: the thoracic cavity, abdominal cavity, and pelvic cavity. These cavities house various organs and are protected by different structures.

Step 2: Recall that the thoracic cavity is located in the chest region and is protected by the rib cage and sternum, which are bony structures.

Step 3: Consider the pelvic cavity, which is located in the lower part of the torso. It is protected by the pelvic bones, providing bony protection to the organs within.

Step 4: Focus on the abdominal cavity, which is located between the thoracic and pelvic cavities. Unlike the thoracic and pelvic cavities, the abdominal cavity lacks bony protection and is instead surrounded by muscles and connective tissues.

Step 5: Conclude that the abdominal cavity is the ventral cavity subdivision that has no bony protection, relying on soft tissues for structural support and protection.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ventral Cavity

The ventral cavity is a major body cavity that is located at the front of the body. It is divided into several subdivisions, including the thoracic cavity, abdominal cavity, and pelvic cavity. This cavity houses vital organs and is essential for understanding human anatomy and physiology.

Bony Protection

Bony protection refers to the structural support and safeguarding provided by bones to the organs within a cavity. In the context of the ventral cavity, certain subdivisions are encased in bony structures, while others are not, which affects their vulnerability and the types of injuries they may sustain.

Subdivisions of the Ventral Cavity

The ventral cavity is subdivided into the thoracic cavity, which is protected by the rib cage, the abdominal cavity, which contains digestive organs, and the pelvic cavity, which houses reproductive organs. Understanding these subdivisions is crucial for identifying which areas are protected by bone and which are not.
