3 important questions on Lecture title - Nociceptors - Nociceptive fibers
Name the 2 nociceptive nerve fibers that carry the signal to your brain determining the sensation that is percieved
Aδ (A-delta) fibers
C fibers
C fibers
What is a structural A delta fibers (Aδ) nocicetors?
What is a functional characteristic as a result of its structure
What are they responsible for?
lightly myelinated and fast-conducting
responsible for the "first pain" the sharp, localized sensation you feel immediately, like when you first stub your toe

What is a structural C fibers nocicetors?
What is a functional characteristic as a result of its structure
What are they responsible for?
unmyelinated
slow-conducting
They communicate the "second pain" a more diffuse, long-lasting dull ache or burning sensation that follows the initial sharp pain
