Question

question
the sensation of proprioception, fine touch, pressure, and vibration from levels at or superior to t₆ is controlled by which tract(s)?
answer
fasciculus cuneatus
fasciculus gracilis
spinothalamic tracts
spinocerebellar tracts
i dont know yet

Explanation:

• Fasciculus cuneatus: Carries sensory information (proprioception, fine touch, pressure, vibration) from upper body (levels at or superior to T₆).
• Fasciculus gracilis: Deals with lower body sensory info (below T₆), so not relevant here.
• Spinothalamic tracts: Transmit pain, temperature, and crude touch, not the specific sensations in question.
• Spinocerebellar tracts: Concerned with unconscious proprioception for motor coordination, not the conscious sensations mentioned.

Answer:

Fasciculus cuneatus
