Tracts Flashcards
what tracts take place in the brainstem?
the vestibulospinal tract and reticulospinal tract
what 3 tracts take place in the ventromedial tract? what is there function?
- vestibulospinal tract
- reticulospinal tract
- tectospinal tract
- postural at axial muscles, limb girdle and proximal limbs
what two things should we know about the vestibulospinal tract?
- stimulates extensors
- inhibits flexors
two things to know about the reticulospinal tract
- stimulates flexors
- inhibits extensors
what two things should we know about the tectospinal tract?
- startle reflex
- muscles of head head and trunk
what two tracts take place in the midbrain?
tectospinal tract and rubrospinal tract
what two tracts comprise the dorsolateral tract? what are their function?
the rubropsinal tract and corticospinal tract
- distal limbs and voluntary movement
what two things should we know about the rubrospinal tract?
- forelimb muscles
- comes from red nucleus
corticospinal tract: 3 things
- distal muscles of both limbs
- fine motor control
- collateral to red nucleus and brainstem
which 3 tracts take place in the cerebral cortex?
- corticospinal tract, corticopontine projection and corticobulbar projection
which two tracts are in the crus cerebri?
the corticopontine projection and the corticobulbar projection
two things to know about the corticopontine projection
- influence cerebellum
- cortex –> pons –> cerebrocerebellum
two things to know about the corticobulbar projection
- influence cranial nerve motor nuclei via reticular formation
- cortex –> reticular formation
