Introduction:
The vertebral column is also referred to as the spinal column. It is a part of the body that is responsible for the protection of the spinal cord. It supports the head and the skull. The vertebrae are the parts of the vertebral column.

Answer to Problem 1RAC
The correct answer is option (d) level of the foramen magnum to the second lumbar vertebra.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) level of the foramen magnum to the second lumbar vertebra. The spinal cord is a very important structure that extends from the brain at the particular level of foramen magnum down to the second lumbar vertebra. It is relatively shorter than the vertebral column due to the lack of rapid growth during the developmental stages. So, the correct answer is option (c).
Explanation for incorrect answer:
Option (a) medulla oblongata to the coccyx. The spinal cord does not extend from medulla oblongata to the coccyx. So, this is an incorrect option.
Option (b) level of the third cervical vertebra to the coccyx. The extension of the spinal cord occurs from the level of the foramen magnum to the second lumbar vertebra. So, this is an incorrect answer.
Option (c) level of the axis to the lowest lumbar vertebra. The spinal cord does not extend from the level of the axis to the lowest lumbar vertebra. So, this is an incorrect answer.
Option (e) axis to the sacral hiatus. The extension of the spinal cord does not take place from the axis to the sacral hiatus. So, this is an incorrect answer.
Thus, an extension of the spinal cord occurs from the level of the foramen magnum to the second lumbar vertebra. Hence, the correct answer is option (d) level of the foramen magnum to the second lumbar vertebra.
