Only the pyramidal system tract has a connection with cerebellum, not the extrapyramidal.
True
False
What are the two pyramidal (volitional) tracts?
corticospinal and corticobulbar
vestibulospinal and rubrospinal
corticospinal and tectospinal
reticulospinal and vestibulospinal
What is the tectospinal tract responsible for?
regulating antigravity tone
linking eye and head motion to body motion; hand-eye and leg-eye coordination
righting/ equilibrium responses
coordination/ movement refinement
There is a lesion at the R internal capsule. Which side of the body is effected?
both
Right side
Left side
What is the reticulospinal tract responsible for?
linking eye and head motion to body
equillibrium responses
coordination and refinement of movement
readiness to contract; regulating antigravity tone
Which accurately describes decorticate posture?
Extension of UE, Flexion of LE
Extension of both UE & LE
Flexion of UE, Extension of LE
Flexion of both UE & LE
What is the pathway of the corticoreticulospinal system?
What is the vestibulospinal tract responsible for?
coordination/ refinement of movement
righting/ equilibrium responses
linking eye and head motion to body motion
regulating antigravity tone
Which extrapyramidal system is at work when you get startled by a loud, unexpected noise?
medial vestibulospinal
tectospinal
rubrospinal
lateral vestibulospinal
What is the tectospinal tract starts in the (a) and ends in the cervical spinal cord.
In what situation would tone be the highest?
sleeping at night
doing yoga
right before a big championship game
leisurely running
The rubrospinal tract starts in the (a) and goes to the interneurons that project to anterior horn to facilitate flexor motor neurons.
Which nucleus is associated with the extensor facilitatory center?
vestibulospinal nucleus
pontine reticular nucleus
medullary reticular nucleus
cranial nuclei
The lateral vestibulospinal tract adjusts position of head in response to changes in posture (keeps head stable while walking).
True
False
What are causes of hypotonicity?
LMNL
UMNL
spinal shock
spasticity
