| back 7 - D: Little finger
- M: by I'm late (little finger
flexion)

dorsiflexion (towards the ground)
|
| back 12 - M: Dorsum of the foot and big toe

|
| back 16 - contains neuronal cell bodies and synapses
- Posterior
horn
- Anterior horn
- Posterior columns
|
| |
| |
| back 19 - transmit proprioception, pressure, and vibration
|
| back 20 - contains ascending and descending pathways
|
| back 21 - ORIGIN: Peripheral receptors; first-order neuron synapses in
medulla
- FUNCTION: Discriminative touch and conscious
proprioception
- TYPE: Conscious relay
|
| back 22 - ORIGIN: Dorsal horn of spinal cord
- FUNCTION:
Discriminative information about
nociception and
temperature - TYPE: Conscious relay
|
front 23 Spinolimbic, spinomesencephalic, spinoreticular | back 23 - ORIGIN: Dorsal horn of spinal cord
- FUNCTION:
Nonlocalized perception of pain;
arousal, reflexive,
motivational, and analgesic responses to nociception (SLOW
nociception) - TYPE:
|
front 24 Posterior spinocerebellar & cuneocerebellar
(MVT) | back 24 - ORIGIN:
- High-accuracy paths: peripheral
receptors
First-order neurons synapse in nucleus dorsalis
or medulla - FUNCTION: Unconscious
proprioceptive information
- TYPE
|
front 25 Anterior spinocerebellar & rostrospinocerebellar
(MVT) | back 25 - ORIGIN: Internal feedback tracts originate in dorsal horn of
spinal cord
- FUNCTION: Unconscious information
about
activity in upper motor neuron pathways and spinal
interneurons - TYPE
|
| back 26 - Three-neuron pathway
- Conscious relay
-
Discriminative touch and conscious proprioceptive
information
-
Primary (first-order) neurons ascend
ipsilaterally
- End in VPL nucleus of thalamus
|
| back 27 - Three-neuron pathway
- Conscious relay
-
Fast pain (localized), temperature,
and coarse
touch information -
Secondary (second-order) neurons ascend
contralateral
- End in VPL nucleus of thalamus
|
| back 28 -
Spinothalamic tract
-
Conscious relay
- The individual is
consciously
aware of sharp
pain in a specific location.
- Quick signal on small, myelinated axons
|
| back 29 -
Spinolimbic tract
-
Divergent relay
- Follows fast pain
-
Slow, aching non-localized pain
- Slower
onset
- Smaller, unmyelinated axons
|
| back 30 - carry sensory information to the brain (ascending pathway)
- touch, pressure, vibration, and proprioception
|
| back 31 - carrying motor commands from the brain to the muscles
(descending pathway)
- some ascending sensory pathways for
pain and temperature
