UNMC Patho Exam 1: Questions With Smart Solutions
what is pain Right Ans - an unpleasant sensory and emotional experience
neuto-anatomical pathway of pain Right Ans - beings at the nociceptors
and is eventually interpreted by the brain
what is a nociceptor Right Ans - a pain receptor
what kind of pain is felt by A-Delta fibers Right Ans - sharp and stinging
what kind of pain is felt by C fibers Right Ans - dull and aching
what is substance P Right Ans - a neurotransmitter peptide
what does substance P bind to Right Ans - NK1 (neurokinin 1)
gate control theory of pain proposes what Right Ans - a gate control system
modulates sensory input
L fibers (Large diameter fibers) Right Ans - conduct impulses fast
task of L fibers Right Ans - attempt to depolarize (excite) SG and T cells
S fibers (Small diameter fibers) Right Ans - slower conduction of impulses
task of S fibers Right Ans - attempt to inhibit SG but excite T cells
SG cell Right Ans - substantia gelatinosa
tasks of SG cell Right Ans - attempts to inhibit T-cell
T cell Right Ans - Central Transmission Cell that receives all input
the more overall excitation of the T cell, the more Right Ans - perception of
pain
If L fibers are more stimulated, which two things will this directly lead to
Right Ans - depolarization (excitation) of SG and T cells
, What does depolarization of SG and T cells lead to Right Ans - more
inhibition of T due to more stimulation of SG
Will more stimulation of SG (more inhibition of T) lead to more or less pain
impulses Right Ans - less due to the action of SG
what is the immune system Right Ans - a complex and intricate network of
specialized cells, tissues, and organs
What do cells of the immune system do Right Ans - seek out and destroy
damaged cells and foreign tissues while recognizing and preserving host cells
what are the three main functions of the immune system Right Ans - 1.
defend and protect the body from infection
2. remove and destroy damaged or dead cells
3. identify and destroy malignant cells, preventing further development of
tumors
what are the body's three main defenses Right Ans - 1. anatomic
2. inflammatory response
3. immune response
anatomic defense Right Ans - physical barriers (skin, mucous membranes,
etc)
inflammatory response Right Ans - nonspecific, quick, involves several
different cell types and plasma systems that occur quickly
immune response Right Ans - specific, slow, involving immunoglobulin and
one cell type
what is the purpose of inflammation Right Ans - defend against infection
and facilitate tissue repair and healing
where does inflammation occur Right Ans - vascular tissue
exudate formation Right Ans - increased amount of plasma and blood cells
that move to the area that needs the response
