NR 546 COMPLETE EXAM STUDY GUIDE WITH PRACTICE
QUESTIONS AND VERIFIED ANSWERS 2025–2026
Neuroscience - correct answer -is the study of the structure and function of the brain and is a
field which is making great advancements
Gray Matter - correct answer -The cerebellum
cerebrum,
brain stem,
and the butterfly-shaped portion of the central spinal cord is comprised of ______matter which
contains neural cell bodies, axon terminals, dendrites, and all nerve synapses.
associated with learning
Changing linked to psychiatric diagnoses including Alzheimer's disease, schizophrenia, and
major depressive disorder
White matter - correct answer -contains nerve fibers that connect neurons from different
regions into functional circuits.
The myelin that coats neuronal axons is necessary for electrical impulse transmission.
Think of the white matter as a transit system. If there are breaks in the system, then people
cannot get to their destinations.
Within the brain, these breaks affect neural communication, affecting behavior.
Damage to the myelin can impair transmission which can impact not only sensory and motor
function, but also cognition
, . White matter abnormalities are associated with autism and vascular dementia.
Frontal Lobes - correct answer -are associated with movement, intelligence, abstract thinking.
the ability to organize, personality, behavior, and emotional control.
Traumatic brain injuries can result in personality changes, difficulty controlling emotions, and
other cognitive functions.
Central Sulcus - correct answer -This separates the frontal lobe from the parietal lobe.
Parietal Lobe - correct answer -The middle part of the brain, responsible for proprioception, is
the home of the somatic senses.
This part of the brain helps a person to identify spatial relationships, interpret pain and touch in
the body, and identify and give meaning to objects.
Damage to the anterior portion of the parietal lobe may cause asterogenesis, the loss of ability
to recognize objects via the sense of touch. This may be experienced by patients with post
cerebral vascular accidents
Temporal Lobe - correct answer -is located on the sides of the brain and involved in short-term
memory, speech, auditory signals, and smell recognition. It identifies "what" things are - object
identification.
It contains the limbic system, amygdala, and hippocampus. There are multiple pathways within
the temporal lobe which affect object identification and language comprehension, including the
ability to understand semantics.
