Which term describes the space that contains the spinal cord?

• A. Spinal Cavity
• B. Nucleus
• C. Organelle
• D. Stem Cell

Answer: (A)

The term for the space that contains the spinal cord is the spinal cavity. It sits in the dorsal body cavity and is enclosed by the vertebral column, shielding the spinal cord much like the cranial cavity shields the brain. The spinal cavity is continuous with the cranial cavity, together forming the dorsal cavity. Nucleus refers to the control region inside a cell, organelle is any specialized structure within a cell, and a stem cell is a type of cell that can become other cell types. None of these describe a body space; they describe cellular components or cell types.
