Spinocerebellar tract

Question 1

What are the spinocerebellar tracts for?

Answer 1

Muscle joint information from muscle spindles, tendon organs and joint receptor.

Question 2

Where do the first order neurons synapse in the spinocerebellar tract?

Answer 2

Base of the posterior gray column (Clarke column) (Nucleus dorsalis) C8-L3/L4

Question 3

Where do the SON fibers go in the dorsal spinocerebellar tract?

Answer 3

The axons enter the posterolateral part of the lateral white column ipsilaterally and ascend to the medulla oblongata.

Question 4

Where do the SON fibers go in the ventral spinocerebellar tract?

Answer 4

The axons cross to the other side and then ascend in the lateral white column and reach to the medulla oblongata

Question 5

Where do the SON fibers of the dorsal spinocerebellar tract terminate?

Answer 5

They terminate in the cerebellum by entering through inferior cerbellar peduncle.

Question 6

Where do the SON fibers of the ventral spinocerebellar tract terminate?

Answer 6

They terminate in the cerebellum by entering through the superior cerebellar peduncle. After entering the cerebellum, these fibers cross to the other side of the cerebellum.

Question 7

What is the posterior spinocerebellar tract for?

Answer 7

Muscle joint info from the trunk and lower limb.

Question 8

What is the anterior spinocerebellar tract for?

Answer 8

Muscle joint info from the trunk and upper and lower limbs. Info from skin and superficial fascia.
