Which type of pain is associated with each?

Definition

unmyelinated C fibers - slow, burning pain

 

lightly myelinated A delta fibers - fast, bright pain

 

(free nerve endings)

Term

What are the 3 ascending nociceptive pathways?

 

Which is involved in modulating/inhibiting pain?

Definition

Spinoreticular

 

Spino-mesencephalic - modulating/inhibiting

Term

What are the 2 dorsal column nuclei?

Which one is more medial?

Definition

Specific (relay) nuclei - receive info from below cortex

 

Association nuclei - receives input from cortex

 

Non-specific nuclei

Term
