Question

question
which of the following statements regarding the spinocerebellar tracts is true?
answer
they carry proprioceptive information concerning the position of muscles, tendons, and joints to the primary sensory cortex.
the axons of first - order sensory neurons synapse on second - order neurons in the anterior gray horns of the spinal cord.
axons that cross over to the opposite side of the spinal cord enter the anterior spinocerebellar tract and ascend to the cerebellar cortex by way of the superior cerebellar peduncle. they do not decussate again.
the posterior spinocerebellar tract carries axons that ascend to the cerebellar cortex by way of the inferior cerebellar peduncle.
i dont know yet

Explanation:

• First option: Proprioceptive information to primary sensory cortex is carried by dorsal column - medial lemniscus pathway, not spinocerebellar tracts.
• Second option: First - order sensory neurons synapse on second - order neurons in the posterior gray horns (not anterior) for spinocerebellar tracts.
• Third option: Anterior spinocerebellar tract axons cross twice (once in spinal cord and once in cerebellum).
• Fourth option: The posterior spinocerebellar tract axons ascend to the cerebellar cortex via the inferior cerebellar peduncle.

Answer:

The posterior spinocerebellar tract carries axons that ascend to the cerebellar cortex by way of the inferior cerebellar peduncle.
