25
Collections of nerve cell bodies outside the central nervous system are called
Ganglia
26
A neuron that has as its primary function the job of connecting other neurons is called
association neuron
27
Saltatory conduction is made possible by
the myelin sheath
28
Neuroglia that control the chemical environment around neurons by buffering potassium & recapturing newurotransmitters are
Astrocytes
29
Schwann Cells are functionally similar to
Oliogodendrocytes
30
immediately after an aciton potential has peaked, which cellular gates open
Potassium
31
An inhibitory postsynaptic potential (IPSP) is associated with
Hyperpolarization
32
Occurs as an excitatroy postsynaptic potential (EPSP) is being generated on adendtritic membrane
A single type of channel will open, permitting simultaneous flow of sodium & potassium
33
When a sensory neuron is excited by some form of energy, the resulting graded potential is called
Generator potential
34
NOT true of graded potentials
Increase in strength as they move away from the stimulus point
35
In what way does the interior surface of a cell membrane of a resting (nonconducting) neuron differ from the external environment. The interior is\_\_\_\_\_\_
Negatively charged & contains less sodium
36
The arbor vitae refers to
Cerebellar white matter
37
The brain stem consists of the
Midbrain medulla pons
38
Primary auditory cortex is located in the
temporal lobe
39
Spinocerebellar tracts
carry proprioceptive inputs to the crebellum
40
Cell line the bentricles of the brain
Ependymal cells
41
The subarachnoid space lies between what 2 layers of meninges
Arachonoid and Pia
42
Cell bodies of the sensory neurons of the spinal nerves are located in
the dorsal root ganglia of the spinal cord
43
A shallow groove on the surface of the cortex is called a
Sulcus
44
The central sulcus separates which lobes
frontal from parietal
45
Spastic paralysis suffests damage to the
upper motor neurons
46
Ridges of tissue on the surface of the cerebral hemishperes are called
gyri
47
2 terms for the masssive motor tracts serving voluntary movement are
Pyramidal & corticospinal
48
Which part of the crebral cortex is involved in intellect, cognition, recall, and personality
perfontal cortex
49
Process of linking new facts with old facts already stored in the memory bank is called
Consolidation
50
The brain area that refulates activites that control the state of wakefulness or alertness of the crebral cortex is the
reticular formation
51
NOT find in normal cerebrospinal fluid
Red Blood Cells
52
REM sleep is associated with
Temporary skeletal muscle inhibition except for the extrinsic eye muscles
53
Structure is probably NOT directly involved in memory
Medulla
54
White matter (myelinated fibers) is found in all of the following locaitons EXCEPT the
Cerebral Cortex
55
2nd-order neurons of both the specific & nonspecific ascending pathways usually terminate in the
Thalamus
56
Brain waves are NOT normal for awake adults but are common for children
THETA
57
Patellar "knee jerk" reflex is an example of a
Stretch reflex
58
What nerves does NOT arise from the brachial plexus
Phrenic
59
NOT an example of an exteroceptor
Baroreceptor
60
NOT a main level of neural integration in the somatosensory
Circuit
61
Spinal nerves exiting the cord from the level of L4 to S4 form the
Sacral plexus
62
Inborn or intrinsic reflexes are
Involuntary, yet may be modified by learned behavior
63
A reflex that causes muscle relaxation & lengthening in response to muscle tension is called
Golgi tendon reflex
64
Pressure, pain, and temperature receptors located in the skin are
exteroceptors
65
Potentially damaging stimuli that result in pain are selectively detected by

Afferent nerves
68
After axonal injury, regeneration in peripheral nerves is guided by
