Verified
The ________ tract and the ________ tract make up the pyramidal system.
A) corticobulbar; spinocerebellar
B) corticospinal; corticobulbar
C) reticulospinal; spinothalamic
D) rubrospinal; reticulospinal
Pyramidal System
A motor system that carries voluntary movements signals from the brain to the muscles, mainly involving the cerebral cortex and the spinal cord.
Corticospinal Tract
A set of nerve pathways that travel from the cerebral cortex in the brain down the spinal cord, involved in controlling voluntary muscle movements.
Corticobulbar Tract
Neural pathways that conduct impulses from the brain's cortex to the brainstem, primarily involved in controlling movements of the face and neck.

Final Answer :
B
Explanation :
The pyramidal system is primarily involved in motor control and consists of the corticospinal tract, which runs from the cortex to the spinal cord, and the corticobulbar tract, which runs from the cortex to the brainstem.
