ANPH 301 Exam 2 Practice Exam Questions And
Accurate Answers
Cerebellum
portion of the vertebrae brain that
maintains proper body position
Calmodulin
calcium binding protein involved in 2nd messenger response
Presynaptic inhibition
diminishes the release of neurotransmitter from the presynaptic terminal
Varicosities
terminal branches of postganglionic fibers designed for diffuse release of
neurotransmitters
Saltatory conduction
depolarization 'jumps' from node to node
Association area
region of cerebral cortex that compares new information with memory
Opsin
photopigment molecule involved in transduction of light energy
, Statocyst
gravity receptor: detection of movement and position
Long term potentiation
increase in the strength of existing synaptic connections
Motor homunculus
depicts the location of motor cortex devoted to output to the muscle of each body part
Acetylcholine
released from the postganglionic fiber of the parasympathetic nervous system
Norepinephrine
released from the postganglionic fiber in the sympathetic nervous system
Tip link
link the stereocilia in adjacent rows
Clusters of ampullae
detect electrical currents produced by other animals
Curare
prevents action potential generation at the muscle endplate
True or False: Stereocilia, the sensory transducers in the neuromast, detect chemical
products emitted from other fishes.
False
