    result to epilepsy or an intense repetitive
    convulsive seizure

your spinal cord withdraw your hand even before
your higher levels of conscious awareness are
notified.
→ ____
▪ An enlargement of the brain stem involved in
regulating bodily functions (e.g., breathing, heart
rate, blood pressure) and certain reflexes. Also
involved in conveying messages to higher brain
centers.
→ ____
▪ A bulb-like structure at the top of the brain involved
in head movements (e.g., chewing or swallowing)
and postural reflexes (keeps your balance as you
move or stand). Also involved in conveying
messages to higher brain centers.
→ ____
▪ Distinct ball-like structure behind the brainstem and
below the cerebrum. It is involved in coordination
and balance. Thus, If there’s a problem in your gait,
then most probably there’s a defect in your
cerebellum.
→ ____
▪ A small structure above the pons; that plays a role in
arousal, vision, and hearing. Damage to this part
leads to movement difficulties associated with
Parkinson’s disease

A

Spinal Cord; Medulla; Pons; Cerebellum; Midbrain

35
Q

Upper Management: Forebrain
→ ____
▪ The thin outer layer of the brain that contains millions of nerve cells (neurons) that influence most of what you think, feel, or do.
→ ____
▪ The cortical “peel” that covers the biggest part of the
brain where most of the important mental function
takes place (e.g., writing song lyrics, performing
scientific experiments).
→ ____
▪ A structure deep within the brain that conveys
sensory information to the cerebrum and other parts
of the brain.
→ ____
▪ Composed of the (1) hypothalamus, (2)
hippocampus, and (3) amygdala, which is important
in motivation and emotions. The latter two are also
important in memory.

Metabolic Syndrome
● Physical Activity and Health
● Sleep
Postprandial Somnolence
● Psychoactive Drugs

43
Q

______
▪ Lowers the body’s overall energy level, reduces
sensitivity to outside stimulation and in high doses,
induces sleep
▪ Often decreases heart rate, respiration rate, muscular coordination and energy while dulling the
senses
▪ Examples: alcohol, barbiturates, benzodiazepines
______
▪ Activates or excites the nervous system – causes
the nerve fibers to release noradrenaline and other
stimulating neurotransmitters
▪ These drugs don’t give a person more energy but
only spends its energy sooner and in greater
quantities than it normally would
▪ Effect: Sleepiness, laziness, mental fatigue, possibly
depression (due to the prevention of dopamine
uptake)
▪ Examples: nicotine, cocaine, caffeine,
amphetamines

A

Depressants; Stimulants

44
Q

______
▪ Also called psychedelics (mind vision)
▪ Can produce hallucinations, cause intoxication and
lead to altered perception and impaired judgment
▪ Physical effects are more constant, and it consists of
CNS stimulation
▪ Chronic use of these drugs can lead to the
psychological effects and impaired judgment
They will mimic the effects of the neurotransmitters
(serotonin and epinephrine), which lessens the
pain
They can also trick the brain into seeing things
and hearing things that are not actually there
▪ Examples: LSD, psilocybin mushrooms and morning
glory seeds

▪ Most widely used psychoactive drugs in the world
▪ Usually found in coffee, tea, chocolates, soft drinks,
and various medications

disturbances, and headaches

A

Caffeine

48
Q

● Through their work, this group found that information alone is rarely enough to motivate one to act - individuals must know what to do and how to do it before they can take action and the information must be related to one’s needs and accurate
● It is based on the assumption that the major determinant of preventive health behavior is disease avoidance.
● Limitation: it assumes that only those clients who have distorted or negative perceptions of the disease or recommended health action will fail to act.
● This model suggests that a person’s beliefs and a
personal threat of an illness or disease together with their belief in the effectiveness of the recommended health behavior or action will predict the likelihood of a person on how he or she will be able to adapt.
