BIO-210 lecture exam 4
1. Nerve impulses are sent parasympathetic division
to slow the heart's rate
of contraction. The nerve
fibers sending these sig-
nals will most likely belong
to which division of the
nervous system?
2. Nerve impulses leading somatic nervous system
to the skeletal muscle
carry information to di-
rect movement. The nerve
fibers sending these sig-
nals will most likely belong
to which division of the
nervous system?
3. Which of the following is They are mitotic
NOT a characteristic of
neurons?
4. When a sensory neuron is generator potential
excited by some form of
energy, the resulting grad-
ed potential is called a(n)
_________________.
5. Some nerve fibers of the schwann cells
PNS have the ability to
regenerate after damage
has occured. Which of the
following cells is most re-
, BIO-210 lecture exam 4
sponsible for aiding in this
regulation?
6. These cells in the CNS have ependymal cells
cilia that move in order to
circulate cerebrospinal flu-
id.
7. Collections of nerve cell ganglia
bodies outside the CNS are
called ___________.
8. Axon diameter and degree true
of myelination determine
nerve impulse conduction
velocity.
9. What is the first step in a Depolarization: voltage-gated Na+ channels open
action potential?
10. What is the second step in Repolarization: Na+ channels are inactivating, and voltage-gated K+
a action potential? channels open
, BIO-210 lecture exam 4
11. What is the third step in a Hyperpolarization: Some K+ channels remain open, and Na+ chan-
action potential? nels rest
12. What is a threshold stimu- Any stimulus at or above this level will result in action potential.
lus?
