Term | Definition |
Fasciculus cuneatus (dorsal column) | sensory tract for trunk, neck, and UE proprioception, vibration, 2-point discrimination, and graphesthesia |
Fasciculus gracilis (dorsal column) | sensory tract for trunk and LE proprioception, vibration, 2-point discrimination, and graphesthesia |
Spinocerebellar tract (dorsal) | sensory tract for ipsilateral subconscious proprioception, tension in mm, joint sense, and posture of the trunk and LEs |
Spinocerebellar tract (ventral) | sensory tract for ipsilateral subconscious proprioception, tension in mm, joint sense, and posture of the trunk, UEs, and LEs |
Spino-olivary tract | sensory tract that relays information from cutaneous and proprioceptive organs |
Spinoreticular tract | sensory tract for the reticular formation that influences levels of consciousness |
Spinotectal tract | sensory tract for spinovisual reflexes and assists w/ movement of eyes and head towards a stimulus |
Anterior spinothalamic tract | sensory tract for light touch and pressure |
Lateral spinothalamic tract | sensory tract for pain and temperature sensation |
Corticospinal tract (anterior) | pyramidal motor tract for ipsilateral voluntary, discrete, and skilled movements |
Corticospinal tract (lateral) | pyramidal motor tract for contralateral voluntary fine movement |
Reticulospinal tract | extrapyramidal motor tract for facilitation or inhibition of voluntary and reflex activity through the influence on alpha and gamma motor neurons |
Rubrospinal tract | extrapyramidal motor tract for motor input of gross postural tone, facilitating activity of flexor mm, and inhibiting the activity of extensor mm |
Tectospinal tract | extrapyramidal motor tract for contralateral postural muscle tone associated w/ auditory/visual stimuli |
Vestibulospinal tract | extrapyramidal motor tract for ipsilateral gross postural adjustments subsequent to head movements; facilitating activity of the extensor mm and inhibiting activity of the flexor mm |
