NURS 751 Midterm Study Guide
1.CNS (central nervous system): consists of the brain and spinal cord
2.PNS (peripheral nervous system): the sensory and motor neurons that
connect the CNS to the rest of the body
-Autonomic- internal involuntary funct.
-Somatic- voluntary
3.Frontal lobe function: associated with reasoning, planning, parts of
speech, movement, emotions, and problem solving
-problem- personality changes
4.temporal lobe function: auditory, receptive speech (werniche)
5.occipital lobe function: vision
6.parietal lobe function: sensation, taste, read/write
-problem- agonosia
7.cerebral cortex function: Is the center for humans highest functions
governing thought, memory, reasoning, sensation and voluntary
movement.
8.Depolarization: Initial (excitatory) - when sodium is rushing into the
cell causing the interior to become more positive.
9.Repolarization: Restoration (inhibitory)- caused by reentry of
potassium into the cell while sodium exits the cell.
10.Dopamine (DA): A monoamine transmitter found in the midbrain—
especially the substantia nigra—and basal forebrain
** Ventral Tegmental Area- Nucleus accumbens.
11.Norepinephrine (NE): a monoamine neurotransmitter in locus of
ceruleus
-involved in alertness and vigilance and control of REM
sleep in mood, anxiety and concentration d/o
12.Epinephrine: Monoamine Neurotransmitter secreted by the adrenal
medulla in response to stress. Also known as adrenaline.
13.Serotonin: a monoamine neurotransmitter in RAPHE nuclei of
brainstem
-important for a wide range of psychological activity, including emotional
states, impulse control, and dreaming
-mood and anxiety d/o
14.Glutamate: Amino acid - excitatory neurotransmitter
- in seizures, mood, bipolar, & schizophrenia
15.Asparate: Amino acid- inhibitory neurotransmitter
16.GABA (gamma-aminobutyric acid): Amino acid- inhibitory
