Question

at the pyramidal decussation, upper motor neurons in the medulla cross from one side of the brainstem to the other side (simultaneously from right to left and also left to right).
which of the following is the remnant tract that does not decussate or \crossover\?

anterior corticospinal tract
corticobulbar tract
lateral corticospinal tract
corticospinal tract

Explanation:

The anterior corticospinal tract is a remnant tract that does not decussate or "crossover" at the pyramidal decussation. The corticobulbar tract, lateral corticospinal tract, and corticospinal tract (in general, as the lateral corticospinal tract is a major part of it) are not the non - decussating remnant tracts in this context.

Answer:

Anterior Corticospinal Tract
