Spinal Tracts

Question 1

The lateral spinothalamic tract is:

a) Ascending
b) Descending

Answer 1

a) Ascending

Question 2

The ascending spinal cord tracts are responsible for carrying what kind of stimuli

Answer 2

Sensory stimuli

From the peripheral to the brain

Question 3

The descending spinal cord tracts are responsible for carrying what kind of stimuli

Answer 3

Motor stimuli from the brain to the periphery

Question 4

The lateral spinothalamic tract is responsible for what kind of stimuli

Answer 4

Ascending tract i.e. carries sensory stimuli

Pain and temperature

Question 5

The ventral (anterior) spinothalamic tract is:

a) Ascending
b) Descending

Answer 5

a) Ascending

Question 6

The ventral (anterior) spinothalamic tract is responsible for what kind of stimuli

Answer 6

Ascending tract therefore carries sensory stimuli

Responsible for pressure and crude (non-discrimination) touch

Question 7

The dorsal column-medial lemniscus pathway is a:

a) Ascending tract
b) Descending tract

Answer 7

a) Ascending

Question 8

The dorsal column-medial lemniscus pathway is responsible for what kind of stimuli

Answer 8

Ascending tract therefore carries sensory stimuli

Responsible for fine touch, vibration, proprioception, two-point discrimination

Question 9

The spinocerebellar tract is:

a) Ascending
b) Descending

Answer 9

a) Ascending

Question 10

The spinocerebellar tract is responsible for what kind of stimuli

Answer 10

Ascending tract - carries sensory stimuli

Responsible for proprioception in joints and muscles

Question 11

The spinotectal tract is:

a) Ascending
b) Descending

Answer 11

a) Ascending

Question 12

The spinotectal tract is responsible for what kind of stimuli

Answer 12

Ascending tract i.e. carries sensory stimuli

Tactile, painful, and thermal stimuli

Question 13

The corticospinal tract is:

a) Ascending
b) Descending

Answer 13

b) Descending

Question 14

The corticospinal tract is responsible for what kind of stimuli

Answer 14

Descending - carries motor stimuli

Responsible for voluntary, discrete and skilled motor activities

Question 15

The reticulospinal tract is:

a) Ascending
b) Descending

Answer 15

b) Descending

Question 16

The reticulospinal tract is responsible for what kind of stimuli

Answer 16

Descending - carries motor stimuli

Responsible for regulation of voluntary movements and reflexes

Question 17

The rubrospinal tract is:

a) Ascending
b) Descending

Answer 17

b) Descending

Question 18

The rubrospinal tract is responsible for what kind of stimuli

Answer 18

Descending - carries motor stimuli

Responsible for promotion of flexor and inhibition of extensor muscle activity

Question 19

The vestibulospinal tract is:

a) Ascending
b) Descending

Answer 19

b) Descending

Question 20

The vestibulospinal tract is responsible for what kind of stimuli

Answer 20

Descending tract - carries motor stimuli

Responsible for the inhibition of flexor and promotion of extensor muscle activity

Question 21

The tectospinal tract is:

a) Ascending
b) Descending

Answer 21

b) Descending

Question 22

The tectospinal tract is responsible for what kind of stimuli

Answer 22

Descending - carries motor stimuli

Responsible for postural movements from visual stimuli
