Dropdown choices:
cuneate fasciculus
gracile fasciculus
spinothalamic tract
spinoreticular tract
spinocerebellar tract
trigeminothalamic tract

Answer for dropdown 1 is Spinothamic tract.

Dropdown 2 is gracile fasciculus

Dropdown3 is Cuneate fasciculus

Dropdown 4 is spinocerebrallar tract

Explanation:

Spinothalamic tract functions by transmitting pain, temperature, touch, itch etc to the somatosensory organ of the thalamus.

Cuneate and gracile fasciculus function by sending sensory information to the upper part of the body like upper limb, trunk entering the spinal cord for the cuneate while the gracile sends sensory information to the lower half of the body entering the spinal cord at the lumber region.

Spirocerebrallar tract function by sending proprioceptive and cutaneous information to the golgi tango organ to the cerebellum.
