Spinal Cord Tracts Flashcards
1
Q
Pressure touch vibration proprioception pathways
A
Dorsal column- medial lemniscus pathway
Peripheral nerves - Dorsal column (dorsal root ganglion) - Medulla - Cross over - Medial lemniscus - Thalamus - Cortex
2
Q
Voluntary movement
A
Lateral corticospinal tract
Pyramidal neurons in cortex -
Cross over in medullary pyramids -
Anterior motor horn (umn) -
Muscle (lmn)
3
Q
Sympathetic input of face
A
Hypothalamospinal tract
Hypothalamus -
Lateral horn at T1 -
Superior cervical ganglion -
Eyelids, pupil, skin of face
4
Q
Pain and temperature pathway
A
Spinothalamic tract
Peripheral nerves - Posterior horn - Dorsal root ganglion - Crosses anterior white commissure - Ascends spinothalamic tract to thalamus - cortex
