Compared to an action potential, a graded potential
is weak and depending on the stimulus strength will dissipate away from the
stimulus.
O is weak and depending on the stimulus strength will maintain its strength as it
travels.
O is all-or-none, and maintains it strength as it travels.
O is all-or-none but weakens as it travels.
Which of the following is the correct sequence
of the neural chain of events set in motion by
an environmental stimulus?
(A) Receptors, afferent neurons, interneurons,
efferent neurons, effectors
(B) Receptors, efferent neurons, interneurons,
afferent neurons, effectors
(C) Interneurons, effectors, receptors, afferent
neurons, efferent neurons
(D) Effectors, interneurons, receptors, afferent
neurons, efferent neurons
(E) Effectors, receptors, afferent neurons, effer-
ent neurons, interneurons
b) You are having a shower with warm water, and all of a sudden, the water turns ice cold! How
do you think your temperature sensory neurons code this very noticeable and strong stimulus?
a) They produce larger EPSPS at the same rate as under the warm water condition.
b) They produce larger, but the same number of, action potentials as under the warm water
condition.
c) They produce smaller EPSPS at a higher rate than under the warm water condition.
d) They produce the same number and size action potentials that travel faster down the neurons
than under the warm water condition.
e) They produce more action potentials of the same size as under the warm water condition

- When they are not being stimulated, neurons have an electrical charge across their membranes called the resting potential. This potential is______ charged inside. When a neuron receives a sufficiently large stimulus, and reaches a potential called the_______ , it produces an action potential. This causes the neuron to become_____ charged inside.arrow_forwardAfter spinning in an office chair and then standing up quickly, you notice that the room is still spinning even though your head rotation has ceased.
