Motor control Flashcards
lateral corticospinal tract?
controls precise movement in limbs and also enables synergistic movement so control of an entire limb.
controls skilled voluntary movements
anterior corticospinal tract?
responsible for postural adjustment related to movement of the limbs and targets the lower motor neurones for trunk and proximal muscles.
where does the corticospinal tract originate?
the primary motor cortex
where does the vestibulospinal tract originate?
vestibular nuclei which are located at the border of the pons and medulla
lateral vesibulospinal tracts function?
control extensor muscle tone to ensure antigravity maintenance of posture.
medial vestibulospinal tracts function?
adjust and stabilise the head during movement.
where does the medial reticulospinal tract originate?
pontine reticular formation
where does the lateral reticulospinal tract originate?
medullary reticular formation
The medial reticulospinal tract function?
facilitates extensor activity and inhibits flexor activity.
The lateral reticulospinal tract function?
it inhibits tone and voluntary movement
where does the tectospinal tract originate?
superior colliculus of the midbrain
tectospinal tract function?
terminate on lower motor neurones that innervate the muscles responsible for neck movements and therefore make adjustments in response to visual stimuli.
where does the rubrospinal tract originate?
red nucleus which is located in the tegmentum of the midbrain
rubrospinal tract function?
innervate the upper limb flexor muscles.
