__________ are bundles of axons moving with the CNS - ✔✔fiber tracts
List all the categories of fiber tracts - ✔✔- spinal tract (ascending and
descending)
- association fibers (within hemispheres)
- commissural fibers (btwn L and R hemispheres)
- projection fibers (ascending/ descending fibers w/in brain)
The lateral horn of the spinal cord is ONLY present in _______________- -
✔✔T1-L1 (sympathetic chain ganglion)
The ____________________ of the dorsal column is present above T7,
while _______________ is present throughout the spinal column. - ✔✔1.
fasciculus cuneatas
2. fasciculus gracilis
- FC = upper extremity --> does not need nerve fibers past T7
- FG = lower extremity

What are the 3 major divisions of the white matter in the spinal cord? - ✔✔-
dorsal column (ascending tracts)
- lateral column (ascending and descending)
- anterior column (ascending and descending)
Describe the blood supply distribution to the spinal cord. - ✔✔- posterior
spinal artery = dorsal column
- anterior spinal artery = anterior and lateral columns (presents w more
deficits and more common)

What is the spinocerebellar system responsible for? - ✔✔- unconscious
proprioception (limb position, joint angle, muscle tone and length)
- cannot be tested clinically
What is the pathway of the DCML tract? - ✔✔sensory info --> dorsal root
ganglion --> dorsal horn --> DCML tract --> medulla (fibers cross sides to
ML) --> VPL nucleus of thalamus --> anterior internal capsule --> S1 cortex
The __________ spinothalamic is responsible for pain and temperature. -
✔✔lateral
The ___________ spinothalamic is responsible for ______ and
____________ - ✔✔crude touch and firm pressure
What is the pathway of the ALS tract? - ✔✔sensory information --> dorsal
root ganglion --> dorsal horn --> ALS tract (fibers cross) --> medulla, pons,
midbrain --> VPL nucleus in thalamus --> anterior internal capsule --> S1
cortex
Where are the 1st, 2nd, and 3rd order neurons in the DCML Tract? - ✔✔1st
= sensory receptors to medulla
2nd = medulla to thalamus
3rd = thalamus to S1 cortex
