midsagittal view - Anterolateral spinothlamic tract

sensory from skin to thalamus to post-central gyrus

decussates at the level of the spinal cord

anterior portion: crude touch

lateral portion: pain and temperature

86
Q

(a) longitudinal intersegmental fibers which arise from cells in the gray substance, more especially from those of the medial group of the anterior column, and, after a longer or shorter course, reënter the gray substance
(b) fibers which cross in the anterior white commissure from the gray substance of the opposite side.

A

midsagittal view - Fasciculus proprius

***unable to find sagittal view or confirm picture used

87
Q
  • conducts impulses from the brain to the spinal cord for voluntary movement.
  • cortex –> post. limb of internal capsule –> through cerebral puduncle into brainstem and ant. medulla–> form medullary pyramids –> fibers cross over below pyramids –> down cord in white matter –> periphery for motor innervation

109
Q
A

Spinal cord - filum terminale

110
Q
A

Spinal cord - conus medullaris

111
Q
A

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.
112
Q
A

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.
113
Q
A

Spinal cord - dorsal spinocerebellar tract

-carries proprioceptive information from muscle spindles and Golgi tendon organs of ipsilateral part of trunk and lower limb

114
Q
A

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.
