What is the function of the brain stem?
The brain stem is the lower part of the brain that's connected to the spinal cord
(part of the central nervous system in the spinal column). The brain stem is
responsible for regulating most of the body's automatic functions that are
essential for life. These include: breathing.
What is the reticular activating system?
a diffuse network of nerve pathways in the brainstem connecting the spinal cord,
cerebrum, and cerebellum, and mediating the overall level of consciousness.
What is the function of the hypothalamus?
regulates function of body, balance, thermoregulation, maintains homeostasis,
releases hormones
What is the function of the cerebellum?
Balance and coordination
The role of neurotransmitters in the central nervous system is to function as
A communication medium
,A gatekeeper for transmissions
synapses
"building blocks of neurotransmitters"
amino acids (and proteins)
enzyme inhibitors
Drugs that prevent the breakdown of neurotransmitters that have been taken up
by the presynaptic neuron (slow down the metabolism therefore increases the
serum level of the drug)
enzyme inducers
drugs that promote induction of enzymes- increase metabolism- decreased serum
levels
This portion of the brain is implicated in addiction medicine. The rewards
pathway lights up in this when substances are abused. It is believed that long
term damage from methamphetamine abuse can lead to loss of interest, flat
affect, and social isolation
Nucleus accumbens
Hippocampus
A neural center located in the limbic system that helps process explicit memories
for storage.
corpus callosum
, the large band of neural fibers connecting the two brain hemispheres and
carrying messages between them
basal ganglia
a set of subcortical structures that directs intentional movements
Hypothalamus
A neural structure lying below the thalamus; it directs several maintenance
activities (eating, drinking, body temperature), helps govern the endocrine system
via the pituitary gland, and is linked to emotion and reward.
What is the most effective strategy for a PMHNP to act as a change agent in
mental health policy?
Serve on a legislative committee
What is the principle excitatory neurotransmitter in the central nervous system?
glutamate
Serotonin
Affects mood, hunger, sleep, and arousal
Dopamine
influences movement, learning, attention, and emotion
Acetylcholine
A neurotransmitter that enables learning and memory and also triggers muscle
contraction
