QuestionChoice
Cervical vertebrae (C1-7) are found in the neck - a lesion in this area would affect all the structures below the patient's head.

QuestionChoice
The sacral vertebrae, S1 to S5, are found in the pelvis - this patient is having symptoms in the lower back as well, which makes a lesion in the lumbar area more likely.

Sacral vertebrae
QuestionChoice
The coccyx is the last segment of the spinal cord, at the end of the sacral spine. It sits in the buttock region, and would therefore produce symptoms in the legs, without any symptoms in the lower back.

Coccygeal vertebrae
QuestionChoice
The lumbar vertebrae contain 5 bones - L1 to L5. These are found in the lower back. The symptoms that this patient is presenting with are consistent with a lesion in this area, as the symptoms begin here and affect all the structures under the lumbar spine. This constellation of symptoms is also known as sciatica and can be caused by a slipped disc or lumbar spinal stenosis (narrowing of the space the spinal nerves pass through the lumbar spine).

QuestionChoice
Thoracic vertebrae (T1-T12) are found in the thorax - this would mean that structures above the lumbar spine would also be affected if the lesion was in the thoracic spine. This is not the case in this man - the lesion is therefore unlikely to be in the thoracic spine.
