Spinal Cord (3)

Question 1

What conscious, high fidelity, somatotopically arranged tract senses the feeling when you stub your toe?

Answer 1

Lateral spinothalamic

Question 2

What is associated with the lateral corticospinal tract?

Answer 2

Fractionated and isolated joint movements (voluntary arms, legs, fingers)

Question 3

What is associated with the medial corticospinal tract?

Answer 3

Axial stability and postural control (voluntary trunk movement)

Question 4

What is associated with the dorsal column medial lemniscus (DCML) system?

Answer 4

Discriminative light touch

Proprioception

Vibration

2 point discrimination

Stretch

Pressure

Question 5

What is associated with the spinocerebellar tracts?

Answer 5

Unconscious proprioception

Question 6

What is associated with the lateral spinothalamic tract?

Answer 6

Discriminative- nociception and temperature

Non discriminative- crude touch

Question 7

What is associated with the anterior spinothalamic tract?

Answer 7

Non discriminative nociception

Question 8

What structures of the spinal cord are motor?

Answer 8

Lateral corticospinal tract

Medial corticospinal tract

Question 9

What structures of the spinal cord are sensory?

Answer 9

Dorsal column medial lemniscus

Lateral spinothalamic tract

Anterior spinothalamic tract

Spinocerebellar tract

Question 10

What type of signs are associated with the cauda equina?

Answer 10

Lower motor neuron signs

Question 11

Conus medullaris

Answer 11

End of the spinal cord (L1-L2)

Question 12

What does it mean when you are aware your tag touched your skin?

Answer 12

Conscious

Question 13

Where does conscious terminate?

Answer 13

Somatosensory cortex

Question 14

High fidelity

Answer 14

Tells you about the accuracy of what you are feeling

Question 15

Discriminative

Answer 15

Differentiation in feelings

Question 16

What does it mean when you are aware that the tag on your skin is not the same feeling as stubbing your toe?

Answer 16

Discrimination

Question 17

What are the 3 parts of the anterior spinothalamic tract?

Answer 17

Spinoemotional/limbic

Spinomesencephalic

Spinoreticular

Question 18

What does the spinomesencephalic do?

Answer 18

Turns head towards pain

Question 19

What does the spinoreticular do?

Answer 19

Arousal to pain

Question 20

What can you not test in the lateral spinothalamic tract?

Answer 20

Crude touch

Spinocerebellum

Anteriospinothalamic

Question 21

Why can you not test Crude touch, Spinocerebellum, and Anteriospinothalamic in the lateral spinothalamic tract as a PT?

Answer 21

Because they do not end up in the spinal somatosensory cortex

Question 22

What do the upper motor neurons not leave?

Answer 22

Spinal cord

Question 23

Where does the spinoemotional tract end?

Answer 23

Emotional areas of cerebral cortex

Question 24

What is the spinoemotional tract responsible for?

Answer 24

Emotional response to pain

Question 25

Where does the spinomesencephalic tract end?

Answer 25

Brainstem

Question 26

What is the function of the spinomesencephalic tract?

Answer 26

Turn eyes and head towards pain

Question 27

Where does the spinoreticular tract end?

Answer 27

Reticular formation of Brainstem

Question 28

What is the function of the spinoreticular tract?

Answer 28

Mediates arousal systems and attention to nociception

Question 29

What is the function of somatic motor neurons?

Answer 29

Transmit motor signals to skeletal muscles from brain

Question 30

What is the function of somatic sensory neurons?

Answer 30

Transmit sensory input from skeletal muscles to brain
