A) rubrospinal and corticospinal
B) spinothalamic and tectospinal
C) vestibulospinal and rubrospinal
D) corticobulbar and vestibulospinal
E) corticospinal and corticobulbar
Extrapyramidal System
A neural network within the brain that is involved in the coordination and regulation of posture and muscle tone, independent of voluntary motor movements.
Rubrospinal
Referring to the rubrospinal tract, which is a pathway in the central nervous system that helps mediate voluntary motor control.
Vestibulospinal
Relating to the vestibulospinal tract, a pathway in the central nervous system that conveys information from the vestibular system to motor neurons controlling limb and trunk muscles for balance.

Final Answer :
C
Explanation :
The extrapyramidal system is involved in the coordination of movement and includes various tracts that are not part of the pyramidal system, which is directly involved in voluntary muscle control. The vestibulospinal and rubrospinal tracts are part of the extrapyramidal system. The vestibulospinal tract helps maintain posture and balance by facilitating the muscles that control these functions, while the rubrospinal tract is involved in motor coordination.
