All of the Following Pathways Require Third-Order Neurons Synapsing in the Thalamus

Question

All of the following pathways require third-order neurons synapsing in the thalamus except
A) the lateral spinothalamic tract.
B) the anterior spinothalamic tract.
C) the anterior and posterior spinocerebellar tracts.
D) the gracile fasciculus.
E) the cuneate fasciculus.

Accepted Answer

The anterior and posterior spinocerebellar tracts do not require third-order neurons synapsing in the thalamus; instead, they carry proprioceptive information directly to the cerebellum for processing.
