Final answer:
Anterior cord syndrome primarily damages the anterior corticospinal tracts and the spinothalamic tracts, leading to loss of motor function in the legs and altered pain and temperature sensation.
Step-by-step explanation:
In anterior cord syndrome, major neuronal tracts are damaged, primarily affecting the anterior corticospinal tracts and the spinothalamic tracts. The anterior corticospinal tracts are responsible for motor function and are situated near the ventral horn, especially affecting the lumbar enlargement that controls the legs. Injury to these tracts may result in compromised motor function but may not necessarily impact the trunk's musculature due to the unlikely event of a spinal cord hemisection affecting only one anterior column
Additionally, damage to the spinothalamic tracts disrupts pain and temperature sensation. In such cases, the diagnosis of anterior cord syndrome is made by identifying bilateral losses in trunk musculature or the presence of other symptoms such as loss of motor function or altered pain and temperature sensation. It is essential to recognize the specific tracts affected to understand the potential impacts and guide treatment strategies effectively.
