Description
1. Dorsal root ganglion cells that innervate muscle spindles may project axons directly into: A. Fasciculus gracilis at cervical levels B. Dorsal spinocerebellar tract C. Cuneocerebellar tract *D. Fasciculus cuneatus 2. Destruction of the left half of the spinal cord (left hemisection) at a single mid-thoracic level will interrupt which of the following: A. Axons conveying discriminative touch from the right toe *B. Axons conveying information to the left cerebellum C. Axons originating in neurons in the right vestibular nuclear complex *D. Axons originating in left lumbar dorsal horns 3. Destruction of which of the following will result in diminished flexor withdrawal from a painful stimulus applied to the left foot: A. Right anterolateral column at a cervical level B. Right pyramid C. Left fasciculus gracilis at a lumbar level * D. Left Lumbar and sacral ventral roots. 4. Destruction of which of the following will result in a deficit in proprioception: *A. Nucleus gracilis B. Rubrospinal tract *C. Fasciculus cuneatus D. Anterolateral column 5. A neuron located in the right nucleus gracilis may: A. Receive a direct axonal connection from a neuron located in the left lumbar dorsal horn. B. Receive a direct axonal connection from a neuron located in the right cervical dorsal horn. C. Project an axon to the left reticular formation. *D. Receive a direct axonal connection from a neuron in the left somatosensory cortex. 6. A right lumbar dorsal horn column neuron that receives an axon from a dorsal root ganglion cell conveying pain may: A. Project an axon directly to the right external cuneate nucleus. *B. Project an axon directly to the right thalamus. C. Project an axon directly to right nucleus gracillis *D. Project an axon directly to the left hypothalamus. 7. An alpha motor neuron may receive a direct axonal connection from: *A. An inhibitory interneuron B. A neuron located in Carke’s nucleus *C. A dorsal root ganglion cell. D. A neuron that projects into the anterolateral white column. 8. The same single uninterrupted axon can be found passing through both: *A. Left pyramid and the left anterior c
