Term 2 of 20
Which of the following statements is false about reflexes?
Reflexes do not require higher levels of voluntary processing from the brain.
Regulation of blood sugar by hormones is one example of a reflex.
Some reflexes can be tested to determine injury.
Pulling a hand away from a hot flame is not a reflex; it is entirely voluntary.

Term 4 of 20
Name and describe what is occurring in the neuron cell membrane in section 4 of the diagram.
Include the charge of the membrane during this phase.
False
There is no variation in the strength of action potentials. (It is an all-or-nothing response).
There is variation in the number and frequency of neurons firing.
afferent or sensory
B. multipolar
Afterpolarization (Hyperpolarization) Potassium gates are slow to close and
there is an undershoot of the potential.
The charge drops below -70mV and then returns to -70mV once at resting
state again.
Term 5 of 20
How is a message sent from one neuron to another?
The neuron cell body manufactures neurotransmitters, which are stored in secretory
vesicles at the end of axon terminals.
nerve
CNS (central nervous system)
There is a minute fluid-filled space, called a synapse, between the axon terminal of the
sending neuron and the dendrite of the receiving neuron. When a nerve impulse reaches
the end of an axon, neurotransmitters are released into the synapse. These bind with a
receptor on the next neuron, opening Na+ gates in the receiving dendrite which causes
depolarization and the impulse is carried.
