- What are NMDA receptors important for?
- Describe the cervical lateral chain.
- a In triggering wide dynamic range (WDR) neurons that are responsible for generalization of specific nociceptive info.
- b Superficial & deep divisions.
Both organized around the aortic arch.
- c Located in the neck. All presynaptic input enters from T1 w/ minor contributions from T2 & T3. Cervical lateral chain ganglia are fused.

- Lower colon & rectum
- Phenomenon where neurons carrying normal sensory info cross over & are interpreted as high intensity pain & accounts for allodynia
- ↑ spontaneous neuronal activity d/t ectopic pacemakers (probably dysfunctional Na channels)
↑ response to stimuli
↓ stimulus threshold (less stimulation required to cause nerves to fire).

5 True/False questions
What are the preganglionic and postganglionic neurotransmitters for the somatic nervous system, the PNS, and SNS? → Somatic: preganglionic-Ach
PNS: preganglionic & postganglionic-Ach
SNS: preganglionic-Ach, postganglionic-NE
In regards to the SNS, where do preganglionic B fibers originate? → In the intermediolateral cell column segments T1-L2 or L3
Where is the cervical sympathetic chain located? → Lies on the anterolateral surface of the vertebral bodies.
Blocking what ganglion will knock out all the sympathetics, why, and what can it result in? → Stellate ganglion. All preganglionic fibers arise below the stellate ganglion.
Could result in Horner's syndrome
What occurs with LTP? → ↑ in receptive field of nociceptive neurons d/t formation of more dendrite connections in the dorsal horn.
Dropout of inhibitory neurons.
