Spinocerebellum

Question 1

What is the role of the spinocerebellum

Answer 1

Error correction

Question 2

What does it comprise of

Answer 2

Vermis and paravermis

Question 3

What is the input

Answer 3

Somatosensory system (unconscious proprioceptive info from muscle spindles and golgi tendon organs)

Question 4

Describe the route of info in the Spinocerebellum

Answer 4

Info from the somatosensory system travels up to the cerebellum via the spinocerebellar tract

Output from the vermis is via fastigal nuclei which projects to the reticular formation. The medial reticulospinal tract originates in the pons and gives us extensio to maintain posture. The lateral reticulospinal tract helps give us flexion

Output from the paravermis is via interposed nuclei. Projects onto the red nucleus in the midbrain which is the origin of the rubrospinal tract. The tract crosses and travels down, and is involved in flexion.

Question 5

What is the route of the spinocerebellar tract

Answer 5

Comes from muscle spindles and golgi tendon organs
Through the dorsal root of the spinal cord
Synapses in spinal cord
Travels ipsilaterally to the cerebellum
