Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The following tract is responsible for crude movement of limbs
A
vestibulocerebellar
B
spinocerebellar
C
corticopontocerebellar
D
None of the above
Explanation: 

Detailed explanation-1: -The dorsal spinocerebellar tract also carries unconscious proprioception to the cerebellum but from the lower limbs and trunk.

Detailed explanation-2: -The spinocerebellar tracts occupy the periphery of the lateral funiculus and carry proprioceptive and cutaneous information from Golgi tendon organs and muscle spindles to the cerebellum for the coordination of movements.

Detailed explanation-3: -The lateral corticospinal tract contains over 90% of the fibers present in the corticospinal tract and runs the length of the spinal cord. The primary responsibility of the lateral corticospinal tract is to control the voluntary movement of contralateral limbs.

Detailed explanation-4: -The spinotectal tract, which enables us to orient our eyes and move our head toward the relevant stimulus. The fibres ascend to synapse in the superior colliculi of the midbrain.

Detailed explanation-5: -The spinoreticular tract is involved in the control of descending modulation, motivational-affective aspects of pain, and also in motor and neurovegetative responses to pain (Millan, 1999).
