Question

question 5 of 10
which spinal tract is located on the posterior funiculi and conduct sensory impulses associated with the senses of touch, pressure, and body movement from skin, muscles, tendons, and joints to the brain?
spino cerebellar tract
fasciculus cuneatus
rubrospinal tract
spinothalamic tract

Explanation:

• The spinocerebellar tract is involved in unconscious proprioception (related to muscle and joint position sense for coordination) but not the touch, pressure as described.
• The fasciculus cuneatus is located in the posterior funiculi (posterior white columns of the spinal cord) and conducts sensory impulses for touch, pressure, and conscious proprioception (senses related to body movement awareness) from the upper body (above T6 spinal level).
• The rubrospinal tract is a motor tract (controls movement) and not a sensory - conducting tract.
• The spinothalamic tract is located in the lateral and anterior funiculi (not posterior) and is mainly for pain, temperature, and crude touch.

Answer:

B. Fasciculus cuneatus
