Which of the following describes a hernia of the meninges of the brain or spinal column?

A hernia of the meninges of the brain or spinal column is specifically referred to as a meningocele. The term "meningocele" comes from the root "meningo," which pertains to the meninges—the protective membranes covering the brain and spinal cord—combined with the suffix "-cele," which means hernia or protrusion.

In this condition, the meninges protrude through a defect in the surrounding bony structures, typically due to congenital malformations. This can lead to various neurological issues depending on the size of the hernia and its location.

The other terms do not relate directly to this condition. For example, atresia refers to the absence or closure of a normal body opening, which doesn't apply to the herniation of meninges. The suffix "-dynia" refers to pain, and would not describe a herniation. The term "cele" can refer to any type of hernia but does not specify that it is related specifically to the meninges. Therefore, the specificity of "meningocele" makes it the correct choice for this condition.
