Descending Neuro Fx
functions of descending neuro tracts
Question | Answer |
---|---|
Rubrospinal Function | -Flexor bias -Gross movement/motor control of limbs -Influences UE more -Proximal control for fine motor movements |
Lateral Corticospinal Function | Fine motor movement/control |
Tectospinal Function | -Visual reflexes -mediates head/neck movement during visual/auditory tracking |
Anteriomedial corticospinal Function | -postural/balance control -neck, trunk, proximal limb musculature |
Medial Reticulospinal Function | -Extension bias -postural control/proximal limb movement and control -mod. sensory input |
Lateral Reticulospinal Function | -Flexion bias -postural control of trunk/proximal limbs -mod. sensory input |
Medial Vestibulospinal Function | -Extension bias -postural head/neck control in response to vestib. stimuli |
Lateral Vestibulospinal Function | -Flexion bias -upright postural trunk control |
Corticobulbar Function | Motor tract to CN |
Medial Longitudinal Fasciculus Function | -Mediates coordinated eye mvmt and reflexes -transmits info needed for most eye mvmt |
