Question 21

thinking about spinal pathways

Answer 21

• ascending (sensory) or descending (motor)
• where does it cross midline

Question 22

2 main ascending pathways and their functions

Answer 22

• dorsal column (fine touch, vibration, proprioception)
• spinothalamic (pain and temperature via the lateral part of the pathway and crude touch via the anterior part.)

Question 23

what is the dorsal column made up of?

Answer 23

• fasciculus cuneatus - upper limb
• fasciculus gracilis - lower limb

Question 24

descending pathways

Answer 24

pyramidal - corticospinal tract

extrapyramidal - rubrospinal, reticulospinal, vestibulospinal, tectospinal

Question 25

corticospinal tract

Answer 25

• voluntary movement of the contralateral side
• splits into anterior and lateral tracts

lateral - crosses midline at pyramids
