Which of the following is a primary function of the backbone (vertebral column)?
A
Producing digestive enzymes
B
Protecting the spinal cord
C
Regulating hormone levels
D
Pumping blood throughout the body
Verified step by step guidance1
Understand the anatomy of the vertebral column: The backbone, or vertebral column, is a series of interconnected bones (vertebrae) that form the central support structure of the body. It is part of the axial skeleton.
Identify the primary function of the vertebral column: The vertebral column serves several key roles, including protecting the spinal cord, providing structural support, and enabling movement and flexibility.
Focus on the spinal cord protection: The spinal cord is a vital part of the central nervous system, responsible for transmitting signals between the brain and the rest of the body. The vertebral column encases the spinal cord within the vertebral canal, shielding it from physical damage.
Eliminate unrelated functions: Producing digestive enzymes, regulating hormone levels, and pumping blood are functions associated with other systems (e.g., digestive system, endocrine system, and circulatory system). These are not related to the vertebral column.
Conclude that the primary function of the vertebral column in this context is protecting the spinal cord, as it is anatomically designed to safeguard this critical structure.
