Question Answer
Fasciculus CuneatusDCML-Sensory tract for the trunk, neck, and UE Proprioception, two-point discrimination, vibration, graphesthesia
Fasciculus GracilisDCML-Sensory tract for the trunk and LE Proprioception, two-point discrimination, vibration, graphesthesia
Posterior SpinocerebellarSensory tract to the cerebellum with Ipsilateral subconscious proprioception, muscle tension, joint sense, posture of the trunk and LE
Anterior SpinocerebellarSensory tract to the cerebellum with Ipsilateral subconscious proprioception, muscle tension, joint sense, posture of the trunk and UE
Spino-olivarySensory tract to the cerebellum Relays information from cutaneous and proprioception organs
SpinoreticularSensory information for the reticular formation Influences levels of consciousness
SpinotectalSpinovisual reflexes Movement of head/eyes towards stimulus
Anterior SpinothalamicSensory tract for Light touch and pressure
Lateral SpinothalamicSensory tract for pain and temperature
Anterior CorticospinalPyramidal tract Ipsilateral voluntary, discrete, skilled movement
Lateral CorticospinalPyramidal tract Contralateral fine motor movement
ReticulospinalExtrapyramidal tract Facilitation/inhibition of voluntary and reflex motion
RubrospinalExtrapyramidal tract Gross postural tone, facilitating activity of flexor muscles Inhibits extensor muscles
TectospinalExtrapyramidal tract Contralateral postural muscle tone activated due to auditory/visual stimuli
VestibulospinalExtrapyramidal tract Ipsilateral gross postural adjustments due to head movement Facilitates extensor muscles and inhibits flexor muscles
