What two body systems protect the spinal cord with a hard covering?

• A. Skeletal and Nervous
• B. Circulatory and Endocrine
• C. Muscular and Digestive
• D. Immune and Respiratory

Answer: (A)

The spinal cord is a vital part of the central nervous system and is protected by a hard covering provided by the skeletal and nervous systems. The skeletal system, through the vertebrae, surrounds and encases the spinal cord, forming a bony structure known as the spinal column or vertebral column. This bony structure serves as a protective barrier against physical injury. Additionally, the nervous system is involved in this protective mechanism through the presence of membranes called the meninges, which consist of three layers (the dura mater, arachnoid mater, and pia mater) that cover and cushion the spinal cord and brain. These layers contribute to the overall protection, ensuring that the delicate nervous tissues are safeguarded from external sources of damage. Understanding this interaction between the skeletal and nervous systems highlights how these body systems work collaboratively to maintain the integrity and safety of the spinal cord, allowing it to function properly in transmitting signals throughout the body.
