Sample item

What structure contains the cell bodies of lower motor neurons in the spinal cord?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Anterior horn

Lower motor neuron cell bodies supplying skeletal muscle lie in the anterior horn of spinal gray matter, while sensory afferents enter dorsally.

Option by option

  • A. Anterior horn (correct)

    Correct: anterior horn contains somatic lower motor neuron cell bodies.

  • B. Lateral ventricle

    Lateral ventricles are cerebrospinal-fluid spaces in the cerebral hemispheres.

  • C. Posterior column

    Posterior columns carry fine touch and proprioceptive pathways.

  • D. Corpus callosum

    Corpus callosum connects the two cerebral hemispheres.
