HOSA Behavioral Health knowledge (Verified) 1.Central Nervous system (CNS)
: includes the brain and spinal cord
2.Brainstem
: contains midbrain, medulla, and pons
3.medulla 1 / 6
2 / 13
: controls vital body functions ex: heart rate, breathing 4.pons
: control the management of sleep, arousal, facial expression
5.cerebellum
: maintaining balance and motor coordination
6.cerebellum : contains more neurons than the rest of the brain 2 / 6

7.midbrain
: controls sensory reflexes, movement, pain
8.reticular formation
: controls mood, arousal, sleep; major source of serotonin and
norepinephrine 9.thalamus
: controls sensation, memory, states of consciousness; receives sen-
sory input from most systems 3 / 6

10.basal ganglia
: voluntary movement; degeneration in Parkinson's, also in- volved
in OCD and ADHD 11.hypothalamus
: involved w/ motivation and homeostasis; regulates tempera- ture,
hunger thirst; directs ANS and endocrine system 12.hippocampus
: formation of long term memories
13.cingulate cortex 4 / 6
5 / 13
: directs ANS; plays role in decision making, emotion, antici- pation of
reward, empathy 14.amygdala
: fear and aggression
15.nucleus accumbens
: reward and pleasure
16.corpus callosum: connects hemispheres
17.cerebral cortex: thin layer of gray matter covering cerebral
hemispheres 18.frontal lobe: primary motor cortex and areas responsible for most 5 / 6

complex cognitive processes
19.Broca's area: speech production in left hemisphere
20.prefrontal cortex: planning behavior, attention, and judgement
21.orbitofrontal cortex: emotion, impulse control
22.occipital lobe: primary visual cortex
23.temporal lobe: primary auditory cortex
24.parietal lobe: primary somatosensory cortex (involved in neglect
syndrome)
