Question 110

Answer 110

Question 111

Answer 111

Spinal cord - fasciculus cuneatus - tract of nerves in the spinal cord that primarily transmits information from the arms. It is part of the posterior column-medial lemniscus pathway. - The fasciculus cuneatus transmits fine touch, fine pressure, vibration, and proprioception information from spinal nerves located in dermatomes C1 through T6.

Question 112

Answer 112

Spinal cord - fasciculus gracilis - bundle of axon fibers in the posterior column-medial lemniscus pathway of the spinal cord and carries information from the middle thoracic and lower limbs of the body - provides conscious proprioception of the lower limbs and trunk to the brainstem. Additional functions of the gracile fasciculus include carrying deep touch, vibrational, and visceral pain information to the brainstem.

Question 113

Answer 113

Spinal cord - dorsal spinocerebellar tract -carries proprioceptive information from muscle spindles and Golgi tendon organs of ipsilateral part of trunk and lower limb

Question 114

Answer 114

Spinal cord - ventral spinocerebellar tract -conveys proprioceptive information from the body to the cerebellum. It is part of the somatosensory system and runs in parallel with the dorsal spinocerebellar tract. Both these tracts involve two neurons. The ventral spinocerebellar tract will cross to the opposite side of the body first in the spinal cord as part of the anterior white commissure and then cross again to end in the cerebellum (referred to as a "double cross"), as compared to the dorsal spinocerebellar tract, which does not decussate, or cross sides, at all through its path.
