tracts Flashcards
DCML path (function)
proprioception, vibration, 2 point discrimination, and graphesthesia
cuneatus (trunk, neck, and UE)
gracilis (trunk, LE)
spinocerebellar tract
dorsal
ipsilateral subconsious propcriopception, tension in muscles, joint sense, posture of trunk and LEs
spinocerebellar tract
ventral
ipsilateral subconscious proprioception tension in muscles, joint sense, posture of trunk and LEs
spinoreticular tract
afferent pathway to the reticular formation that influences levels of consciousness
spinotectal tract
provides afferent information for spinovisual reflexes and assists with movement of eyes and head towards a stimulus
spinothalamic tract (anterior)
sensory tract for light touch and pressure (ipsilateral)
spinothalamic tract (lateral)
sensory tract for pain and temperature sensation (opposite side)
corticospinal tract (anterior)
tract responsible for ipsilateral voluntary, discrete, and skilled movements
corticospinal tract (lateral)
tract responsible for contralateral voluntary fine movement
reticulospinal tract
responsible for facilitation or inhibition of voluntary and reflex activity though the influence on alpha and gamma motor neurons
rubrospinal tract
responsible for motor input of gross postural tone, facilitating activity of flexor muscles, and inhibiting the activity of extensor muscles
tectospinal
contralateral postural muscle tone associated with auditory/visual stimuli
vestibulospinal tract
ipsilateral gross postural adjustments subsequent to head movements, facilitating activity of the extensor muscles, and inhibiting activity of the extensor muscles
