(NU 334 EXAM #1) Part 2 Questions and Answers Already Passed Latest Update 2025-2026
Surface of the cerebrum is called - Answers cerebral cortex (4 lobes; may play a role in
emotional experience; evidenced by changes when the area is damaged)
frontal lobe of cerebrum - Answers thinking, judgement formation, expression of feelings,
speaking, voluntary body movement
Parietal lobe of cerebrum - Answers perception and interpretation of sensory info
(parietal/perception)
temporal lobe of cerebrum - Answers short term memory, expression of emotions though
connection with limbic system, hearing
(temporal/closet to limbic system)
occipital lobe of cerebrum - Answers visual reception and interpretation (occipital lesions can
cause visual hallucinations)
(occiput/ocular)
limbic system is also called - Answers the emotional brain
limbic system is composed of many structures most notably (6) - Answers amygdala, pituitary,
hippocampus, hypothalamus*, thalamus* and neuronal connecting pathways
Limbic system is associated with feelings of - Answers o Fear and anxiety
o Anger, rage and aggression
o Love, joy and hope
o Sexuality and social behavior
The tissue of the Central Nervous System (CNS) consists of nerve cells called - Answers
neurons that generate and transmit electrochemical impulses
neuron is composed of (3) - Answers cell body, an axon, dendrites
synapses - Answers junction between two neurons
Neurons conducting impulses toward a synapse - Answers presynaptic cells
Neurons conducting impulses away - Answers postsynaptic neurons
Neurotransmitters - Answers chemicals stored in the axon terminals of presynaptic neurons
, neurotransmitters are responsible for the - Answers role of human emotion and behavior
(Also target for the mechanism of action of many psychotropic meds)
Major categories of NT (4) - Answers - cholinergic
- monoamines
- amino acids
-neuropeptides
Categories of Neurotransmitters: cholinergic - Answers - affects sympathetic and
parasympathetic system
- Affects sleep, arousal, pain perception, movement (motor control), learning, and memory
- Cholinergic may have role in disorders of motor behavior and memory such as Alzheimer's
disease (also Parkinson's disease, Huntington's disease)
Categories of Neurotransmitters: monoamines - Answers - Norepinephrine
- Dopamine
- Serotonin
- Histamine
Categories of Neurotransmitters: amino acids (2) - Answers -inhibitory amino acids (gamma-
aminobutyric acid: slowdown of body a activity)
-excitatory amino acids (Glutamate: relay of sensory info and regulation of motor/spinal
reflexes)
Categories of Neurotransmitters: Neuropeptides (3) - Answers - endorphins
- substance P
- somatostatin
Monoamines: Norepinephrine* - Answers active chemical associated with fight or flight
(role: regulation of mood, cognition, perception, CV functioning, sleep and arousal*)
Monoamines: Dopamine* - Answers - Role: regulation of emotions, decision making/judgment,
attention, cognition, movement and coordination
