Draw the tracts

Using the CNS worksheets (see Haines pg. 253) or a blank sheet of paper, the inputs and outputs of the:

• Posterior Cerebellar lobe
• Anterior cerebellar lobe
• Flocculonodular lobe

Give the names of the cerebellar lobes

Name the Lobe

Name the structure

Where do the inputs to the posterior lobe of the cerebellum decussate?

1. Rostral pons
2. Caudal midbrain
3. Middle pons
4. Rostral medulla

Where do the outpurs from the posterior lobe of the cerebellum decussate?

1. Rostral pons

A 23 YOM is brought to the ED after a motor vehicle accident. He presents with weakness in the right lower extremity and loss of pain and thermal sensation on his left side beginning at the umbilicus. Damage to which tracts would explain the observed weakness?

1. Left corticospinal tract
2. Reticulospinal fibers on the right
3. Right lateral corticospinal tract
4. Right rubrospinal fibers
5. Vestibulospinal fibers
