NM Tracts Flashcards
Dorsal column/medial lemniscus
Proprioception, vibration, tactile discrimination
Fasciculus cuneatus (UE) - lateral Fasciculus gracilis (LE) - medial
Spinothalamic
Pain and temperature (lateral tract) Crude touch (anterior tract)
Spinocerebellar
Proprioceptive information from GTO, muscle spindles, and touch/pressure receptors
—> to cerebellum for control of voluntary movements
Spinoreticular
Chronic and deep pain to reticular formation
Corticospinal tract
Voluntary motor control
Vestibulospinal tract
Control of muscle tone,
antigravity muscles,
and postural reflexes
Rubrospinal tract
Arises in C/L red nucleus
Motor function
Reticulospinal tract
Arises in reticular formation
Modifies transmission of sensation (esp pain) and influences GMN and spinal reflexes
Tectospinal tract
Assist in head turning and response to visual stimuli
