Advanced neurobiology exam 2 comprehensive Questions
and Answers with 100% Correct Answers | Latest Version
Question 1.
sensation includes
Correct Answer: touch, pain, itch, olfaction, sight, sound, gustation, equilibrium
Question 2.
Olfactory information is first re- ceived by which part of the brain?
Correct Answer: olfactory cortex
Question 3.
sensory pathways project to
Correct Answer: the thalamus, where they are then processed and sent off to other
cortical centers
Question 4.
Equilibrium pathways project to
Correct Answer: the cerebellum
Question 5.
free nerve end- ings
Correct Answer: light touch pain, itch, hot/cold slow adaptation mediated by
intracellular transduction
Question 6.
Meissner's corpuscles
Correct Answer: light touch sensitive to low frequency vibrations fast adaptation
mediated by collagen
Question 7.
Merkel cells
Correct Answer: /neurite complex light touch found on fingerprints slow adaptation
mediated by neurites
Question 8.
Ruffini corpuscles
Correct Answer: muscle and skin stretch slow adaptation mediated by epithelium
cells
, Question 9.
Pacinian corpuscles
Correct Answer: deep touch slow or fast adaptation mediated by epithelium cells
Question 10.
rapidly adapting receptors
Correct Answer: only respond at the beginning of stimulus good at detecting changes
in a stimulus
Question 11.
slowly adapting receptors
Correct Answer: respond throughout stimulus duration good at providing information
about spatial attributes such as size and shape
Question 12.
braile letters
Correct Answer: sensed by meissner's corpuscles
Question 13.
intrafusal muscle fibers
Correct Answer: surrounded by a capsule of connective tissue 4 to 8 of these make
up a muscle fiber
Question 14.
extrafusal muscle fibers
Correct Answer: parallel arrangement with intrafusal true force-producing fibers
Question 15.
primary endings in muscle fibers
Correct Answer: arise from largest group Ia afferents have rapidly adapting
responses to changing in muscle length transmit information about limb dynamics
Question 16.
secondary end- ings in muscle fibers
Correct Answer: arise from group 2 produce sustained responses to constant muscle
lengths provide information about the static position of limbs
