Unit 2: Somatosensory Pathways To Cerebellum Flashcards
Lower body proprioceptive axons that enter the spinal cord below T6 and travel up the spine in the Ventral Spinocerebellar Tract decussate where?
- At the segmental level in the spinal cord AND 2. within the medullary center of the cerebellum to the opposite side of cerebellum
Upper body proprioceptive axons that enter the spinal cord ABOVE T6 and travel up the spine in the Ventral Spinocerebellar Tract decussate where?
They don’t decussate.
Lower body proprioceptive axons that enter the spinal cord below T6 and travel up the spine in the Ventral Spinocerebellar Tract have 3˚ neurons where?
Ipsilateral cerebellum
The cuneocerebellar tract is made up of fibers that are projecting from where and to where via what?
From lateral cuneatus nucleus (medulla) going to ipsilateral cerebellum VIA ICP
The cerebellum is intimately involve in what?
unconscious control or coordination of skeletal muscles used in maintaining posture, locomotion and other motor activities.
Pathways from the lower body that give input to the cerebellum?
- dorsal spinocerebellar tract
- ventral spinocerebellar tract
Pathways from the upper body that give input to the cerebellum?
- cuneocerebellar tract
