Question

Syrinx expansion in syringomyelia may lead to damage to the lower motoneurons of the anterior horn. What are the consequences of this damage?

1) Muscle atrophy and weakness with decreased muscle tone and impaired reflexes
2) Paresis of paravertebral muscles resulting in scoliosis
3) Both A and B
4) None of the above

Answer 1

The consequences of damage to the lower motoneurons in the anterior horn due to syrinx expansion in syringomyelia include muscle atrophy and weakness, decreased muscle tone and impaired reflexes, and paresis of paravertebral muscles leading to scoliosis.

Step-by-step explanation:

The consequences of damage to the lower motoneurons of the anterior horn due to syrinx expansion in syringomyelia include muscle atrophy and weakness with decreased muscle tone and impaired reflexes.

These symptoms are known as hypotonia and result from damage to parts of the central nervous system (CNS) and loss of innervations to skeletal muscles.

Additionally, damage to the lower motoneurons may lead to paresis of paravertebral muscles, which can result in scoliosis.
