PHYSIO ASCENDING TRACTS

Fasciculus cuneatus

→ Carries vibration, fine touch, and conscious proprioception from upper body (upper limbs, trunk, neck)

Fasciculus gracilis

→ Carries sensory information (fine touch, vibration, proprioception) from lower body

Ventral spinothalamic tract (anterior spinothalamic)

→ Carries crude touch (just knowing you are being touched) and firm pressure

Lateral spinothalamic tract

→ Carries pain and temperature sensations

Spinotectal tract

→ Helps suppress/modulate pain by projecting to midbrain (periaqueductal gray)

Dorsal spinocerebellar tract

→ Carries unconscious proprioception to cerebellum (coordination of movement)

Ventral spinocerebellar tract (anterior spinocerebellar) (and dorsal does this)

→ Carries unconscious proprioception to cerebellum for movement coordination

Spinoreticular tract

→ Carries pain signals that trigger arousal and automatic responses to injury

Spino-olivary tract

→ Carries proprioceptive info to olivary nuclei; helps with movement and balance coordination

Spinocervical tract

→ Carries touch and pressure sensations to the brain via cervical relay nuclei
