The cortico-bulbar tract descends through the brainstem and controls neurons of
all of the cranial nerve nuclei
corticobulbar tract controls cranial nerve nuceli on which side of the body
Cortical control over the Cranial N. nuclei is predominantly bilateral
Control to the Hypoglossal Nucleus is predominantly contralateral
Control to the Facial Nucleus is… BOTH…
The cortico-pontine tract descends to terminate on the _____
pontine nuclei in the basis of the pons.
Axons from the corticopontine nuclei forward the signals to the cerebellum on the ___ side.
what is the course of the cortico-rubro-olivary circuit)
cortex --> red nucleus ---> inferior olive ---> cerebellum
what does the corticospinal tract control?
motor neurons of the trunk and limbs
In the brainstem lateral corticospinal axons descend on the same side as their cortical origin until the
pyradmial decussation in the caudal medulla
which corticospinal tract continues ipsilaterally?
anterior corticospinal tract (only 15%)
brainstem-spinal pathways collectively control
themuscles of the neck, trunk, and limbs
damage to a Brainstem-spinal pathways at the level of the medulla wiill cause
problems with movement on the opposite side of the body
damage to a Brainstem-spinal pathways at the level of the spinal caord wiill cause
problems with mvoement on the same side of the body
