what are the two branches of the spinothalamic tract

anterior spinothalamic tract, lateral spinothalamic tract

two individual ascending tracts

spinotectal tract, spinoreticular tract

what are the four branches of the spinocerebellar tract

anterior, cuneocerebellar, posterior, rostral

what are the three ascending spinal tracts that break off into smaller branches

spinothalamic tract, dorsal column-medial lemniscal tract, spinocerebellar tract

other names for post central gyrus

primary somatosensory area, s1, brodmann's 312

lesion of the lateral spinothalamic tract, hemi-section injury of the spinal cord

contralateral loss of pain and temperature on opposite side

lesion of the lateral spinothalamic tract, stroke affecting s1

contralateral loss of pain and temperature

lesion of anterior spinothalamic tract, complete spinal cord injury

no touch or pressure sensations below injury bilaterally

lesion of anterior spinothalamic tract, stroke affecting s1

contralateral loss of touch and pressure

the receptors in medial lemniscal pathways are

mechanoreceptors, muscle spindles, golgi tendon organs

medial lemniscal pathway complete spinal cord injury

medial lemniscal pathway incomplete spinal cord injury

ipsilateral loss of touch and proprioception below level of injury

medial lemniscal pathway stroke affecting internal capsule

contralateral loss of touch and proprioception

medial lemniscal pathway stroke affecting s1

contralateral loss of touch and proprioception

function of spino tectal tract

motor response of looking at a stimulus
