Spinal Tracts Flashcards
The lateral spinothalamic tract is:
a) Ascending
b) Descending
a) Ascending
The ascending spinal cord tracts are responsible for carrying what kind of stimuli
Sensory stimuli
From the peripheral to the brain
The descending spinal cord tracts are responsible for carrying what kind of stimuli
Motor stimuli from the brain to the periphery
The lateral spinothalamic tract is responsible for what kind of stimuli
Ascending tract i.e. carries sensory stimuli
Pain and temperature
The ventral (anterior) spinothalamic tract is:
a) Ascending
b) Descending
a) Ascending
The ventral (anterior) spinothalamic tract is responsible for what kind of stimuli
Ascending tract therefore carries sensory stimuli
Responsible for pressure and crude (non-discrimination) touch
The dorsal column-medial lemniscus pathway is a:
a) Ascending tract
b) Descending tract
a) Ascending
The dorsal column-medial lemniscus pathway is responsible for what kind of stimuli
Ascending tract therefore carries sensory stimuli
Responsible for fine touch, vibration, proprioception, two-point discrimination
The spinocerebellar tract is:
a) Ascending
b) Descending
a) Ascending
The spinocerebellar tract is responsible for what kind of stimuli
Ascending tract - carries sensory stimuli
Responsible for proprioception in joints and muscles
The spinotectal tract is:
a) Ascending
b) Descending
a) Ascending
The spinotectal tract is responsible for what kind of stimuli
Ascending tract i.e. carries sensory stimuli
Tactile, painful, and thermal stimuli
The corticospinal tract is:
a) Ascending
b) Descending
b) Descending
The corticospinal tract is responsible for what kind of stimuli
Descending - carries motor stimuli
Responsible for voluntary, discrete and skilled motor activities
The reticulospinal tract is:
a) Ascending
b) Descending
b) Descending
The reticulospinal tract is responsible for what kind of stimuli
Descending - carries motor stimuli
Responsible for regulation of voluntary movements and reflexes
The rubrospinal tract is:
a) Ascending
b) Descending
b) Descending
The rubrospinal tract is responsible for what kind of stimuli
Descending - carries motor stimuli
Responsible for promotion of flexor and inhibition of extensor muscle activity
The vestibulospinal tract is:
a) Ascending
b) Descending
b) Descending
The vestibulospinal tract is responsible for what kind of stimuli
Descending tract - carries motor stimuli
Responsible for the inhibition of flexor and promotion of extensor muscle activity
The tectospinal tract is:
a) Ascending
b) Descending
b) Descending
The tectospinal tract is responsible for what kind of stimuli
Descending - carries motor stimuli
Responsible for postural movements from visual stimuli
